Codsiga Ceramics Silicon Carbide ee Goobta Semiconductor

Semiconductors:

Warshadaha semiconductor-ka waxay raacaan sharciga warshadaha ee "hal jiil tiknoolijiyada, hal jiil oo geeddi-socod ah, iyo hal jiil oo qalab ah", iyo cusboonaysiinta iyo soo-celinta qalabka semiconductor waxay inta badan ku xiran tahay horumarka tignoolajiyada ee qaybaha saxda ah. Kuwaas waxaa ka mid ah, qaybaha dhoobada saxda ah waa agabka qaybaha saxda ah ee semiconductor-ka ugu badan, kuwaas oo leh codsiyo muhiim ah oo taxane ah oo isku xirka wax soo saarka semiconductor sida kaydinta uumiga kiimikada, kaydinta uumiga jirka, ion implantation, iyo etching. Sida biraha, biraha hagaha, dahaarka, chucks electrostatic, gacmaha farsamaynta farsamada, iwm. Gaar ahaan gudaha godka qalabka, waxay ka ciyaartaa doorka taageerada, ilaalinta, iyo leexinta.

Laga soo bilaabo 2023, Nederland iyo Japan waxay sidoo kale si isdaba joog ah u soo saareen xeerar cusub ama go'aamo ganacsi shisheeye oo ku saabsan xakamaynta, iyagoo ku daray xeerarka shatiga dhoofinta ee qalabka semiconductor oo ay ku jiraan mashiinnada lithography, iyo isbeddelka semiconductor anti-globalization ayaa si tartiib tartiib ah u soo baxay. Muhiimadda ay leedahay xakamaynta madaxbannaan ee silsiladda sahayda ayaa noqotay mid caan ah. Iyada oo la kulma baahida loo qabo meelaynta qaybaha qalabka semiconductor, shirkadaha gudaha ayaa si firfircoon u kor u qaadaya horumarinta warshadaha. Zhongci Electronics waxay xaqiiqsatay deegaanaynta qaybaha saxda ah ee tignoolajiyada sare sida taarikada kuleyliyaha iyo chucks electrostatic, xallinta dhibaatada "qoorta dhalada" ee warshadaha qalabka semiconductor ee gudaha; Dezhi New Materials, oo ah shirkad hormuud u ah iibiyeyaasha gudaha ee saldhigyada garaafyada dahaarka leh ee SiC iyo giraangiraha SiC, ayaa si guul leh u dhammaystiray maalgelinta 100 milyan yuan, iwm…..
Waxyaalaha dhoobada ah ee silikoon nitride ah oo tayo sare leh:

Substrate-yada dhoobada ee Silicon nitride waxaa inta badan lagu isticmaalaa unugyada korantada, aaladaha semiconductor iyo rogoyaasha baabuurta korantada saafiga ah (EVs) iyo gawaarida korantada ee isku dhafka ah (HEVs), waxayna leeyihiin suuqyo waaweyn iyo rajooyin codsi.

Waqtigan xaadirka ah, qalabka kuleylka sare ee silikoon nitride dhoobada dhoobada ee codsiyada ganacsiga waxay u baahan yihiin kuleylka kuleylka ≥85 W / (m · K), xoog foorarsiga ≥650MPa, iyo adkaanta jabka 5 ~ 7MPa·m1 / 2. Shirkadaha sida dhabta ah u leh awooda ay ku soo saari karaan heerkul sare silikoon nitride dhoobada dhoobada ah ayaa u badan Toshiba Group, Hitachi Metals, Kiimikada Korantada ee Japan, Japan Maruwa iyo Japan Fine Ceramics.

Cilmi-baaris gudaha ah oo ku saabsan silikoon nitride maaddooyinka dhoobada dhoobada ayaa sidoo kale sameeyay xoogaa horumar ah. Wanaajinta kulaylka ee substrate dhoobada nitride silikoon oo ay diyaarisay habka shubista cajaladda ee Laanta Beijing ee Sinoma High-Tech Nitride Ceramics Co., Ltd. waa 100 W / (m · K); Machadka Cilmi-baarista Artificial Crystal ee Beijing Sinoma iyada oo la wanaajinayo habka iyo habka sintering.
