Kugwiritsa ntchito Silicon Carbide Ceramics mu Semiconductor Field

Semiconductors:

Makampani opanga ma semiconductor amatsatira lamulo la mafakitale la "m'badwo umodzi waukadaulo, m'badwo umodzi wazinthu, ndi zida za m'badwo umodzi", ndipo kukweza ndi kubwereza kwa zida za semiconductor kumadalira makamaka pakupita patsogolo kwaukadaulo kwa magawo olondola. Zina mwa izo, zida za ceramic zolondola kwambiri ndi zida zoyimira bwino kwambiri za semiconductor, zomwe zimakhala ndi ntchito zofunika pamalumikizidwe akuluakulu opanga ma semiconductor monga kuyika kwa nthunzi wamankhwala, kuyika kwa nthunzi wakuthupi, kuyika ma ion, ndi ma etching. Monga zimbalangondo, njanji kalozera, linings, chucks electrostatic, makina akugwira mikono, etc. Makamaka mkati zida patsekeke, amasewera mbali ya thandizo, chitetezo, ndi kupatutsidwa.

Kuyambira 2023, Netherlands ndi Japan adaperekanso motsatizana malamulo atsopano kapena malamulo amalonda akunja olamulira, ndikuwonjezera malamulo a chilolezo chotumizira kunja kwa zida za semiconductor kuphatikiza makina a lithography, ndipo mayendedwe a semiconductor anti-globalization ayamba pang'onopang'ono. Kufunika kodzilamulira kodziyimira pawokha kwa njira zoperekera zinthu kwayamba kuonekera kwambiri. Poyang'anizana ndi kufunikira kwa magawo a zida za semiconductor, makampani apakhomo akulimbikitsa chitukuko cha mafakitale. Zhongci Electronics yazindikira kukhazikitsidwa kwa zida zamakono zamakono monga mbale zotenthetsera ndi ma chucks a electrostatic, kuthetsa vuto la "bottleneck" la mafakitale apanyumba a semiconductor; Dezhi New Materials, wotsogola wotsogola m'nyumba zoyambira za SiC zokutira ma graphite ndi mphete za SiC, amaliza bwino ndalama za yuan 100 miliyoni, ndi zina…..
High-conductivity silicon nitride ceramic substrates:

Magawo a Silicon nitride ceramic amagwiritsidwa ntchito makamaka pamagawo amagetsi, zida za semiconductor ndi ma inverter a magalimoto amagetsi amagetsi (EVs) ndi magalimoto amagetsi osakanizidwa (HEVs), ndipo ali ndi mwayi waukulu wamsika komanso chiyembekezo chogwiritsa ntchito.

Pakali pano, matenthedwe apamwamba a silicon nitride ceramic gawo lapansi zida zopangira malonda zimafunikira matenthedwe matenthedwe ≥85 W/(m·K), mphamvu yopindika ≥650MPa, ndi kulimba kwa fracture 5~7MPa·m1/2. Makampani omwe ali ndi kuthekera kopanga kuchuluka kwa matenthedwe apamwamba a silicon nitride ceramic substrates ndi Toshiba Group, Hitachi Metals, Japan Electric Chemical, Japan Maruwa ndi Japan Fine Ceramics.

Kafukufuku wapakhomo pazitsulo za silicon nitride ceramic substrate nayenso wapita patsogolo. Kutentha kwa silicon nitride ceramic substrate yokonzedwa ndi njira yopangira tepi ya Beijing Nthambi ya Sinoma High-Tech Nitride Ceramics Co., Ltd. ndi 100 W/(m·K); Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. yakonza bwino gawo lapansi la silicon nitride ceramic yokhala ndi mphamvu yopindika ya 700-800MPa, kulimba kwa fracture ≥8MPa·m1/2, ndi matenthedwe ≥80W/(m·K) ndi kukhathamiritsa njira sintering ndi ndondomeko.
