    "Demand for AMD's new 7nm EUV processors remains robust, with development projects for the chips commenced by PC, motherboard and graphics card makers this year set to be 10-20% higher than the levels in 2019, according to industry sources."

    TSMC & STMicroelectronics .. kooperáció a 10x gyorsabb chipek miatt.

    "STMicroelectronics and TSMC are collaborating to accelerate the development of gallium nitride (GaN) process technology and the supply of both discrete and integrated GaN devices to market. Through this collaboration, ST's products will be manufactured using TSMC's GaN process technology, according to the companies."
    "GaN is a wide bandgap semiconductor material which offers significant benefits over traditional silicon-based semiconductors for power applications. These benefits include greater energy efficiency at higher power, leading to a substantial reduction in parasitic power losses. GaN technology also allows the design of more compact devices for better form factors. Additionally, GaN-based devices switch at speeds as much as 10X faster than silicon-based devices while operating at higher peak temperatures. These robust and intrinsic material characteristics make GaN ideally suited for broad-based adoption in evolving automotive, industrial, telecom, and specific consumer applications across both the 100V and the 650V clusters."

    Ami érdekes, hogy emlitik CEA-Leti -t , akik a 96core-os 6 chipletes procit csinálták.

    ""This cooperation complements our existing activities on power GaN undertaken at our site in Tours, France and with CEA-Leti. GaN represents the next major innovation in power and smart power electronics, as well in process technology," said Marco Monti, president of STMicroelectronics' automotive and discrete Group."

    megj:
    - A gallium nitride (GaN) -os technológiát a chipset-es architektúra jól ki tudja használni
    ( egy adott funkciójú lapot a neki ideálist gyártástechnológián gyártanak )
    "The semiconductor material used to make each chiplet is not limited to silicon, which is another chiplet advantage. For example, specialized chiplets could be made from a variety of composite semiconductor materials including SiGe (silicon germanium), GaAs (gallium arsenide), GaN (gallium nitride), or InP (indium phosphide) to exploit the unique electronic properties of these semiconductor materials." ( link PDF )

    persze a probléma ott van, hogy Kínához köthető a világ gallium termelésének a 95%-a
    és az 5G-s termékek is erősen fogyasztják. ( link )

    És meg kell még említeni, hogy az Intel is elég sok pénzt tol a szilícium alternatívájának keresésébe - vagyis a TSMC is versenykényszerben van.
