Gukoresha Silicon Carbide Ceramics mumasomo ya Semiconductor

Amashanyarazi:

Inganda ziciriritse zikurikiza amategeko yinganda y "igisekuru kimwe cyikoranabuhanga, igisekuru kimwe cyibikorwa, hamwe nigisekuru kimwe cyibikoresho", kandi kuzamura no gusubiramo ibikoresho bya semiconductor biterwa ahanini niterambere ryikoranabuhanga ryibice byuzuye. Muri byo, ibice bya ceramic byuzuye nibyo byerekana cyane igice cya semiconductor ibikoresho byerekana neza, bifite akamaro gakomeye murukurikirane rwibikorwa byingenzi bikoreshwa mu bice bya semiconductor nko guhumeka imyuka ya chimique, kubitsa imyuka yumubiri, gutera ion, no gutobora. Nkibikoresho, imiyoboro ya gari ya moshi, imirongo, amashanyarazi ya electrostatike, amaboko yo gukoresha imashini, nibindi cyane cyane imbere yu mwobo wibikoresho, bigira uruhare rwo gushyigikira, kurinda, no gutandukana.

Kuva mu 2023, Ubuholandi n'Ubuyapani nabwo bwagiye busohora amabwiriza mashya cyangwa amabwiriza y’ubucuruzi bw’amahanga ku kugenzura, hiyongeraho amabwiriza y’uruhushya rwo kohereza mu mahanga ibikoresho bya semiconductor harimo n’imashini za lithographie, kandi imyumvire ya semiconductor anti-globalisation yagiye igaragara buhoro buhoro. Akamaro ko kugenzura kwigenga kugemura ibintu byagaragaye cyane. Mu guhangana n’ibisabwa kugira ngo ibice by’ibikoresho bya semiconductor bihindurwe, ibigo byimbere mu gihugu biteza imbere iterambere ry’inganda. Electronics ya Zhongci yatahuye aho ibice byubuhanga buhanitse nko gushyushya amasahani hamwe na chucks ya electrostatike, gukemura ikibazo cy '“icyuho” cy’inganda zikoresha ibikoresho byo mu rugo; Dezhi New Materials, umuyobozi wambere mu gihugu utanga ibicuruzwa bya SiC yubatswe hamwe nimpeta ya SiC, yarangije gutera inkunga ingana na miliyoni 100 Yuan, nibindi… ..
Umuyoboro mwinshi wa silicon nitride ceramic substrates:

Silicon nitride ceramic substrate ikoreshwa cyane cyane mumashanyarazi, ibikoresho bya semiconductor hamwe na inverter yimodoka zifite amashanyarazi meza (EVs) hamwe n’ibinyabiziga bikoresha amashanyarazi (HEVs), kandi bifite amahirwe menshi yo kwisoko no gukoresha ibyifuzo.

Kugeza ubu, amashanyarazi menshi ya silicon nitride ceramic substrate ibikoresho byubucuruzi bisaba ubushyuhe bwumuriro ≥85 W / (m · K), imbaraga zunama 50650MPa, hamwe no gukomera kuvunika 5 ~ 7MPa · m1 / 2. Ibigo bifite ubushobozi bwo gukora cyane-kubyara amashanyarazi menshi ya silicon nitride ceramic substrate ni cyane cyane Toshiba Group, Hitachi Metals, Japan Electric Chemical, Japan Maruwa nu Buyapani Ceramics.

Ubushakashatsi bwo murugo kuri silicon nitride ceramic substrate ibikoresho nabyo byateye imbere. Amashanyarazi yubushyuhe bwa silicon nitride ceramic substrate yateguwe nuburyo bwo gufata kaseti ishami rya Beijing ishami rya Sinoma High-Tech Nitride Ceramics Co., Ltd. ni 100 W / (m · K); Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. yateguye neza insimburangingo ya silicon nitride ceramic substrate ifite imbaraga zingana na 700-800MPa, gukomera kuvunika ≥8MPa · m1 / 2, hamwe nubushyuhe bwumuriro ≥80W / (m · K) mugutezimbere uburyo bwo gucumura.
