    Vishay Honored by DENSO with 2022 Collaboration Award

    1 Min Read

    Vishay Intertechnology, Inc. announced that it has been honored by DENSO Corporation, a leading mobility supplier, with a 2022 Collaboration Award.

    The 2022 Collaboration Awards recognize suppliers that have continued to provide DENSO with key components that keep production lines moving for the company and its customers, despite the tight supply market. Previously this year, Vishay was also recognized by DENSO with a 2022 North America Business Partner of the Year Award in the Quality Leader category.

    “Vishay has demonstrated a strong commitment to supporting DENSO on both a working and management level,” said Kouji Arima, CEO of DENSO. “We sincerely appreciate the company’s unsparing efforts and contributions, and know we can count on them regardless of the market situation. We look forward to building an even stronger partnership with Vishay as we continue working together.”

    “We are deeply honored to receive this acknowledgment from DENSO of our unwavering support during challenging market conditions,” said Joel Smejkal, President and CEO at Vishay. “This recognition underscores our commitment to operational excellence and the strength of our partnership with the company. We look forward to building on this level of collaboration to grow together in the coming years.”

  • DENSO and USJC Announce Mass Production Shipment of Automotive IGBT

    DENSO and USJC Announce Mass Production Shipment of Automotive IGBT

    3 Min Read

    DENSO CORPORATION (DENSO), a leading mobility supplier, and United Semiconductor Japan Co., Ltd. (“USJC”), a subsidiary of global semiconductor foundry United Microelectronics Corporation (“UMC”), announced a joint collaboration to produce insulated gate bipolar transistors (IGBT), which have entered mass production at the 300mm fab of USJC. A first shipment ceremony was held last week to mark this important milestone. It comes just one year after the companies announced a strategic partnership for this critical power semiconductor used in electric vehicles.

    As adoption of electric vehicles accelerates, automakers are seeking to boost powertrain efficiency while also increasing cost-effectiveness of electrified vehicles. The jointly invested line at USJC supports the production of a new generation of IGBT developed by DENSO, which offers 20% reduction in power losses compared with earlier generation devices. Production is expected to reach 10,000 wafers per month by 2025.

    The ceremony was held at USJC’s fab in Mie Prefecture, Japan. Attendees included by DENSO President Koji Arima, UMC Co-President Jason Wang, USJC President Michiari Kawano, Director-General of the Commerce and Information Policy Bureau at Japan’s Ministry of Economy, Trade and Industry (METI) Satoshi Nohara, Governor of Mie Prefecture Katsuyuki Ichimi, and Mayor of Kuwana City Narutaka Ito.

    “Today, we are thrilled to welcome a memorable shipping ceremony that symbolizes the partnership between DENSO, UMC and USJC. We are from different cultures such as semiconductor industry and automobile industry. However, we have worked steadily with mutual respect which is a source of our strong competitiveness. DENSO, together with our trusted partners, will continue to further accelerate electrification through the production of competitive semiconductors in order to preserve the global environment and create a society full of smiles,” said Koji Arima, President of DENSO.

    “USJC is proud to be the first semiconductor foundry in Japan to manufacture IGBT on 300mm wafers, offering customers greater production efficiency than the standard fabrication on 200mm wafers. Thanks to our dedicated teams and support from DENSO, we were able to complete trial production and reliability testing without delay and honor the mass production date as agreed with the customer,” said Michiari Kawano, President of USJC.

    “It is an honor to be a strategic partner of DENSO, a leading automotive solution provider to global automakers. This collaboration fully demonstrates UMC’s manufacturing capability and our collaborative approach to ensure the success of our foundry customers,” said Jason Wang, Co-President of UMC. “The electrification and automation of cars will continue to drive up semiconductor content, particularly for chips manufactured using specialty foundry processes on 28nm and above nodes. As a specialty technology leader, UMC is well positioned to play a bigger role in the automotive value chain and enabling our partners to capture opportunities and win market share in this rapidly evolving industry.

  • DENSO Develops Its First SiC Inverter

    DENSO Develops Its First SiC Inverter

    2 Min Read

    DENSO CORPORATION announced that it has developed its first-ever inverter with silicon carbide (SiC) semiconductors. This inverter, which is incorporated in the eAxle, an electric driving module developed by BluE Nexus Corporation, will be used in the new RZ, Lexus’ first dedicated battery electric vehicle (BEV) model has been released on March 30, 2023.

    SiC power semiconductors consist of silicon and carbon that significantly reduce power loss compared with silicon (Si) power semiconductors. The verification of cruising test in a certain condition, which test was performed by BEV consisted of SiC semiconductor inverters, demonstrated inverters with SiC power semiconductor reduce power loss less than half of ones with Si semiconductor. As a result, the energy efficiency of BEVs is improved and cruising range is extended.

    Key elements of developing the new inverter:

    • SiC power semiconductors with DENSO’s unique trench-type metal-oxide-semiconductor (MOS) structure improve the output per chip due to reducing the power loss caused by heat generated. The unique structure achieved high voltage and low on-resistance operation.

    Key elements of manufacturing the new inverter:

    • Based on the high-quality technology jointly developed by DENSO and Toyota Central R&D Labs., Inc., we utilize SiC epitaxial wafers that incorporate the results of work commissioned by New Energy and Industrial Technology Development Organization (NEDO). As a result, we have halved the number of crystal defects that prevent the device from operating normally due to the disorder of the atomic arrangement of the crystal.
    • By reducing crystal defects, the quality of SiC power semiconductor devices used in vehicles and their stable production are ensured.

    DENSO calls its SiC technology “REVOSIC®,” and uses it to comprehensively develop technologies for products ranging from wafers to semiconductor devices and modules such as power cards.

    DENSO will contribute to the realization of a carbon-neutral society through development aimed at more efficient energy management for vehicles, while also utilizing the grant from Green Innovation Fund (GI Fund), which was adopted in 2022.
