Aikace-aikace na Silicon Carbide Ceramics a Filin Semiconductor

Semiconductors:

Masana'antar semiconductor ta bi ka'idar masana'antu na "ƙarni na fasaha, ƙarni na tsari, da kuma ƙarni na kayan aiki", kuma haɓakawa da haɓaka kayan aikin semiconductor ya dogara ne akan ci gaban fasaha na daidaitattun sassa. Daga cikin su, madaidaicin sassan yumbu sune mafi yawan wakilcin kayan aikin daidaitaccen semiconductor, waɗanda ke da mahimman aikace-aikace a cikin jerin manyan hanyoyin haɗin gwiwar masana'antu na semiconductor kamar jigilar tururin sinadarai, jigilar tururi ta jiki, dasa ion, da etching. Irin su bearings, rails na jagora, linings, electrostatic chucks, injin sarrafa makamai, da dai sauransu. Musamman a cikin rami na kayan aiki, yana taka rawar tallafi, kariya, da karkatarwa.

Tun daga 2023, Netherlands da Japan suma sun yi nasarar fitar da sabbin ka'idoji ko dokokin kasuwancin waje game da sarrafawa, suna ƙara ƙa'idodin lasisin fitarwa don kayan aikin semiconductor ciki har da injunan lithography, kuma yanayin haɓakar semiconductor anti-globalization ya bayyana a hankali. Muhimmancin kulawa mai zaman kanta na sarkar samar da kayayyaki ya zama sananne. Fuskantar buƙatun ƙaddamar da sassan kayan aikin semiconductor, kamfanonin cikin gida suna haɓaka haɓaka masana'antu sosai. Zhongci Electronics ya gane yadda ake gano manyan sassan fasaha na fasaha kamar su dumama faranti da chucks electrostatic, warware matsalar "bottleneck" na masana'antar kayan aikin semiconductor na gida; Dezhi New Materials, babban mai samar da gida na SiC mai rufin graphite tushe da SiC etching zoben, ya samu nasarar kammala samar da kudade na yuan miliyan 100, da sauransu…..
Silicon nitride yumbura mai ƙarfi mai ƙarfi:

Silicon nitride yumburayin yumbura ana amfani dashi galibi a cikin sassan wutar lantarki, na'urorin semiconductor da inverters na motocin lantarki masu tsabta (EVs) da motocin lantarki masu haɗaɗɗiya (HEVs), kuma suna da babbar damar kasuwa da fatan aikace-aikace.

A halin yanzu, babban thermal conductivity silicon nitride yumbu substrate kayan don kasuwanci aikace-aikace bukatar thermal watsin ≥85 W / (m · K), lankwasawa ƙarfi ≥650MPa, da kuma karaya tauri 5 ~ 7MPa·m1 / 2. Kamfanonin da da gaske suna da ikon yin taro-samar da manyan abubuwan da ake amfani da su na siliki nitride yumburamin yumbu sune galibin Toshiba Group, Hitachi Metals, Chemical Electric Japan, Japan Maruwa da Fine Ceramics na Japan.

Binciken cikin gida akan kayan yumbura nitride na silicon nitride shima ya sami ɗan ci gaba. The thermal conductivity na silicon nitride yumbu substrate shirya ta hanyar tef-simintin aiwatar da Beijing Reshen Sinoma High-Tech Nitride Ceramics Co., Ltd. ne 100 W / (m · K); Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. ya samu nasarar shirya wani silicon nitride yumbu substrate tare da lankwasawa ƙarfi na 700-800MPa, karaya taurin ≥8MPa·m1/2, da thermal watsin ≥80W/(m·K) ta hanyar inganta hanyar sintering da tsari.
