irose Electric Co., Ltd., a leading manufacturer that specializes in connectors, has been promoting the enhancement of basic technological expertise for the development of new products and technologies that match market needs, while focusing on “Quality First”. The company also gives strong emphasis on investments to strengthen its manufacturing capabilities. By field, the company targets robust growth in the three pillars of 1) automobiles, 2) industrial equipment, and 3) consumer electronics.

Hirose Electric is holding a special exhibition from Nov. 24, 2020 through Jan. 29, 2021 on the first floor of its head office building in Yokohama, Kanagawa Prefecture, Japan.

At the venue, the company set up wearable and portable, industrial, smart home, and automotive. Some of the the company’s experts introduce Hirose’s leading-edge connectors that are used in respective applications in an easy-to-understand manner.

The company takes thorough measures against possible infections of the novel coronavirus disease (COVID-19) at the event place. “We have adopted an advance reservation-only system to control the number of visitors who can enter the venue. Many acrylic panels are installed to prevent the spread of airborne droplets. We sterilize the venue every time after each visit of a group of visitors,” notes Hirose Electric.

Philippine Electronics Eyes Recovery After Pandemic Blow

fter reeling from one of the longest and strictest lockdowns imposed by any country to combat the dreaded novel coronavirus disease (COVID-19) pandemic, Philippine electronics expects a rosier outlook in 2021 with 7 percent growth forecast. This as the industry was seen to close 2020 with 5 percent decline in output.

In an interview with Asia Electronics Industry (AEI), Semiconductor and Electronics Industries in the Philippines Inc. (SEIPI) President Dan Lachica said the better-than-expected demand towards the latter part of 2020 has pulled up the full-year forecast from the more pessimistic 15 percent contraction, which was projected earlier at the height of the country’s battle with the pandemic.

“With the recovery of the global supply chain and the ramp up to full capacity, electronic companies were poised to meet the high global demand for electronics products. Unfortunately, this was not enough to offset the major setbacks at the onset of COVID,” said Lachica.

PV Module Makers Pave Way for Recycling Business


ost establishments in Japan have installed photovoltaic power generation systems, and recently, moves to recycle solar cell module have started emerging. Solar cell modules makers predict that by 2030 a higher number of solar cell modules will be disposed, which will become a concern. Thus, manufacturers rush the establishment of recycling technologies and systems, thinking that it holds the key to sustain the expansion of photovoltaic power generation systems after the feed-in-tariff (FIT) scheme for renewable energy has expired. Under FIT, contracts between residential consumers and electric utilities are predetermined to expire after a ten-year period. It involves the utilities’ purchase of excess photovoltaic power generated by facilities owned by the consumers.

Since the start of FIT in July 2012, the installation of photovoltaic power generation systems has progressed nationwide. As the lifespan of panels is estimated to be 20 to 30 years, it is estimated that the amount of end-of-life solar cell modules that will be disposed will sharply increase in 2033, and peak between 2035 and 2037, at 170,000 to 280,000 tons per year. This is equivalent to about 2 percent of final disposal volume of industrial waste in FY2015. The shortage of disposal sites in the future is also a concern.

These connectors are available to Japanese, European and American automotive manufacturers and tier 1 suppliers.

Transmittance Plays Key Role in Transparent Displays

lthough there is no strict definition of “transparent display,” in general, displays that are usually transparent like window panes and in which images can be displayed are referred to as transparent displays. Head-up displays (HUDs) that project vehicle speed and other parameters on the windshields are also transparent displays.

This article discusses Panasonic Corporation’s direct-view active-matrix organic light-emitting diode (AMOLED) transparent display and Japan Display Inc.’s (JDI) thin-film transistor LCD (TFT-LCD) transparent display, which have recently been developed.

Glass Antenna Technology Expands Mobile Area Coverage


n recent years, with the proliferation of smartphones, the traffic of mobile communications systems has dramatically increased. In high traffic areas, such as huge cities where communications concentrate, it is important to install small cell with smaller coverage and lower antennas height on the rooftop of building and steel tower, and to distribute mobile traffic. To construct an ideal area coverage, it is desirable that antennas for small cells are installed in mid-rise buildings. However, there have been many cases where installation was difficult because of several reasons, among them, impairing the aesthetic features of a landscape.

To avoid the antennas from impairing the landscape of an area, the installation of antennas inside the buildings to establish a wireless service area on the exterior side can be considered. However, in general, when radio waves propagate from indoors to outdoors or from outdoors to indoors, they are shielded by windows of buildings and a major loss occurs, and therefore, the construction of an ideal area coverage has been difficult.

Hitachi High-Tech Pitches Electron Sources for Metal 3D Printing

Electron sources are used in electron microscopes in metal 3D printing, and with the expected high demand for 3D printing, high prospects are also expected for single-crystal electron sources.

itachi High-Tech Corporation intends to expand sales of single-crystal electron sources manufactured by Applied Physics Technologies, Inc. (APTech), a group company of Hitachi High-Tech, through its global sales network. Single-crystal electron sources are presently used in electron microscopes in metal 3D printing markets.

In most manufacturing processes, the molds used in the manufacturing of metallic and resin components make mass production more efficient. However, in cases of manufacturing prototypes or in high-mix low-volume production, the time and cost involved in making molds has become a major challenge. This is why 3D printers, in which structure is formed by layering metal or resin, have been garnering attention in recent years. Not only can this technology produce a prototype from design data without the use of a mold, but through the use of additive layers, it can also reduce the size of designs and components and the number of components, which is difficult when using conventional production methods.

In addition, with the use of 3D printing technology being promoted as national policy around the world, such as under Germany’s Industry 4.0, China’s Additive Manufacturing Industry Development Action Plan, and India’s Make in India, market forecasts predict that the equipment market, which was ¥120 billion (US$1.07 billion) in 2017, will grow by up to five times that by 2030.

KEL Expands Variations of Floating Connector

EL Corporation has expanded the variations of floating connectors, which are the company’s strategic products, with the development of DT Series connector with 25mm stacked mating height. The company will deploy the new product to a wide range of markets, including automotive electronics and factory automation (FA) equipment. The DT Series 0.5mm-pitch floating connectors support high-speed transmission.

In Dec. 2019, KEL developed a product with a stacked mating height of 30mm in the DT Series. This time, the company has added a product with a stacked mating height of 25mm, thereby expanding its lineup of the high-functional and high-stacked mating height type connectors.

The company has achieved the stacked mating height of 25mm by developing a plug-side connector with a stacked mating height of 15mm, and by mating it with a receptacle-side connector with its stacked mating height increased by 10mm. Like the 30mm stacked mating height connector, the 25mm stacked mating height product provides ±1.0mm of float in both X and Y directions. Furthermore, by combining it with the existing receptacle side connector of the DT Series, it can be used as a 15mm stacked mating height product. The 15mm type provides ±0.5mm of float.

Vital Techniques Improve Performance of Organic Semiconductors

he University of Tokyo, University of Tsukuba, Kitasato University, and National Institute of Advanced Industrial Science and Technology (AIST) have succeeded in the development of coating-type n-type organic semiconductor material with high reliability, high mobility, and high resistance to atmosphere, heat, and bias stress for the first time in the world. Organic semiconductors, in which π-electron molecules are aggregated by a weak intermolecular force, have lightweight and mechanically flexible characteristics.

Furthermore, their low-temperature production by printing method dramatically reduces production costs and environmental load. Therefore, they are expected as a key material in the next generation of printed flexible electronics.

Efficient Design Guideline
In contrast to inorganic semiconductors, however, charge transport occurs via weak overlap of molecular orbitals rather than strong covalent bonds and therefore the charge mobility remains low in organic semiconductors. Furthermore, in organic semiconductors, molecules are bound by weak intermolecular forces and perform molecular motion (intermolecular vibration) due to thermal energy even in their solid state. As a result, the charge mobility is lowered as has been pointed out by various reports.

Crystalline Silicon Solar Cells Tap Titanium Oxide for Thin Film

he National Institute of Advanced Industrial Science and Technology (AIST) has conducted a joint research with Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Germany on crystalline silicon solar cells. As a result, a titanium oxide thin film (thickness of about 5nm) formed by atomic layer deposition method has the function of passivating the surface defects of crystalline silicon having a texture structure and of selectively extracting holes from crystalline silicon. They prototyped a crystalline silicon solar cell with this titanium oxide thin film on the positive electrode side and demonstrated a conversion efficiency of over 20 percent, sufficient for practical use.

Details of Research
In the present research, a titanium oxide film is formed by atomic layer deposition method using a material composed of organometallic complex containing titanium and water vapor. This film is used in the positive electrode of the fabricated solar cell. The fabrication process is as follows: First, an n-type crystalline silicon with a surface having a pyramid-shaped texture structure is prepared. Then, amorphous titanium oxide film with a thickness of about 5nm is deposited on the surface, a transparent electrode of tin-doped indium oxide (ITO) is deposited, and a grid-shaped electrode consisting of silver (Ag) is formed. A negative electrode has a structure the same as that of conventional heterojunction crystalline silicon solar cells.

ASIC-Based OCXO Handles High Ambient Temperature of 5G Base Stations

o achieve high-speed, highcapacity communication and ultra-low latency communication brought by fifth-generation (5G) communications system and local 5G, an area has to be covered by a large number of small 5G base stations. These small base stations will be installed on top of outdoor steel poles, rooftops, walls, and other narrow spaces; and the environment surrounding installation sites are exposed to direct sunlight, wind, and rain. These factors demand more stringent requirements for electronic devices.

Smallest in Class
To meet these demands, Nihon Dempa Kogyo Co., Ltd. (NDK) has developed one of the smallest-class oven-controlled crystal oscillator (quartz oscillator with a temperature chamber). NH7050SA measures 7×5mm for small 5G base stations and has an operation upper limit temperature of up to +95°C. Miniaturization has been achieved by developing a dedicated application specific integrated circuit (ASIC) that contains all of the oscillator circuits, temperature-control circuits, and other components of OCXO in a single chip.

New Technology Delivers Greater Safety in In-Vehicle Control

eveloped for in-vehicle touch control applications, Alps Alpine Co., Ltd. has developed the HAPTIC Reactor Heavy Type for strong vibration force in compact size. The product, which generates power vibrations in touch feedback operations, is already available for mass production starting January 2021 targeting the automotive market.

The use of touch input has been rising in the automotive field, enabling integration and multifunctionality of controls that are traditionally operated with the use of switches or dials. Even in applications outside car navigation and audio, touch control is expected to keep growing, not only because of design consideration but also in view of user interface (UI) and user experience (UX).

Samsung Makes Giant Steps in Building Chip-Making Ecosystem

hree decades after it conquered the global memory chip market in 1994, Samsung Electronics Co., Ltd. sets out a new, ambitious path to step up the company’s semiconductor design and fabrication ecosystem, declaring the start of the era of K-chip, an abbreviation that is reminiscent of a global cultural phenomenon called as “K-pop” or Korean Pop culture.

On June 25, Samsung announced that it has been working together with its ecosystem partners to strengthen its chip-making ecosystem by helping them develop new raw materials and new equipment. The step-up effort is a crucial part of Samsung’s ambition to jump to No. 1 foundry chip maker by 2030.

Back in mid-2019, Samsung announced its strong intention to become the No.1 system LSI chip maker by 2030, investing 133 trillion won in the wafer fabrication infrastructure and ecosystem build-up project.

Samsung Foundry Brings Out New Design Ecosystem for 4nm, 3nm Chips

he foundry business of Samsung Electronics Co., Ltd. has been stepping up its technological skills to fabricate chips with highly advanced chip design and leading–edge packaging technologies.

At the annual Samsung Investment Forum 2020 held in late November, Samsung’s foundry service announced that it will build its own 4nm and 3nm chip design ecosystem around Multi-Bridge Channel Field Effect Transistor (MBCFET) and Gate-All-Around Field Effect Transistor (GAAFET) channeling technology.

MBCFET is a new breed of gate channeling technology spun out of the GAA FinFET technology. Comprised of multi-stacked nano sheets, the MBCFET is the more powerful version of GAAFET that does not require additional areas to improve performance. This is because nano sheets can be vertically stacked, while FinFET needs fins to be added laterally.

Components Makers Resume Capital Investments on Full Scale

lectronic components manufacturers resume their in-vestments in plants and equipment on full scale. Their business performance, which deteriorated amid the pandemic caused by novel coronavirus disease (COVID-19), has begun to recover with the resumption of full-scale economic activities. In addition to the recent increase in orders, positive signs are seen for future demand as well. Efforts to level the demand and supply and bolster production systems to expand business performance have also surfaced.

Electronic component manufacturers announced their business performance in the first half (April to September) of the term ending March 2021 one after another. In summary, demand stagnated in Q1 (April to June) reeling from the major impact brought by the COVID-19 pandemic, and business performance deteriorated more than expected. In Q2 (July to September), economic activities started to recover in several parts of the world, as measures to prevent COVID-19 were being taken, slowly picking up demand.

Silver Lining in Business Environment
Manufacturers’ business performance in the first half of the year approached the level of the same period of the previous year. In Q2 alone, some companies posted record performance. Generally, bright signs have been seen in the management environment. One company after another are revising upward their business performance forecasts for the entire fiscal year.

Use of Metal Power Inductors in Automotive Gathers Steam

he development of automotive-grade and metal-based power inductors has been gathering momentum. In various power supply circuits of automobiles, ferrite (Ni-Zn)-based inductors have conventionally been mounted. However, amid the progress of connected, autonomous, shared & services, and electric (CASE) trends, a wide range of requirements, including stronger safety systems, advancement toward autonomous driving, and environment-friendliness and energy savings, have been emerging. For these reasons, there have been growing clamor to propose metal-based power inductors that feature compact size and support high current.

In automobiles, relatively large ferrite-based power inductors have been typically used in power supply circuits that require high inductance. However, they pose some challenges including less compatibility with high current compared with metal material inductors and relatively large magnetic leakage flux. For these reasons, it has been difficult for them to be used in high-current and high-density automotive electric circuits.

Compact SMDs Beef up Role in Latest Devices

ith the progress of surface-mount technologies (SMT) as backdrop, technologies for chip components or surface-mount devices (SMDs) have been advancing remarkably. The growing needs for high-density mounting of fifth-generation (5G) communications-compatible smartphones and internet of things (IoT) terminals, as well as electronic control units (ECUs) and various modules in vehicles, accelerate the downsizing and functional enhancement of SMDs.

The pandemic caused by the novel coronavirus disease (COVID-19) restricted companies’ business activities. However, since summer, manufacturers restarted their production activities on full scale. With these moves, the production of various electronic devices, manufacturing equipment and automobiles has been revitalized.
