Sabbin Hanyoyi a Masana'antar Semiconductor: Aikace-aikacen Fasahar Rufe Kariya

Masana'antar semiconductor tana shaida ci gaban da ba a taɓa gani ba, musamman a fagensilicon carbide (SiC)wutar lantarki.Tare da manyan-sikelin da yawawaferFabs da ake yin gini ko faɗaɗa don biyan buƙatun na'urorin SiC a cikin motocin lantarki, wannan haɓakar yana ba da damammaki masu ban mamaki don haɓaka riba.Koyaya, yana kuma haifar da ƙalubale na musamman waɗanda ke buƙatar sabbin hanyoyin warwarewa.

A zuciyar haɓaka samar da guntu na SiC na duniya ya ta'allaka ne da kera manyan lu'ulu'u na SiC, wafers, da yadudduka na epitaxial.Nan,semiconductor-sa graphitekayan suna taka muhimmiyar rawa, suna sauƙaƙe ci gaban SiC crystal da kuma jibgewar yadudduka na SiC epitaxial.Rufin zafin jiki na graphite da rashin aiki sun sa ya zama abin da aka fi so, ana amfani da shi sosai a cikin crucibles, pedestals, disks planetary, da tauraron dan adam a cikin ci gaban crystal da tsarin epitaxy.Duk da haka, yanayin ƙayyadaddun tsari yana haifar da ƙalubale mai mahimmanci, wanda ke haifar da raguwa da sauri na abubuwan graphite kuma daga baya ya hana samar da ingantattun lu'ulu'u na SiC da yadudduka na epitaxial.

Samar da lu'ulu'u na silicon carbide yana haifar da yanayi mai tsauri, gami da yanayin zafi sama da 2000 ° C da abubuwan iskar gas mai lalata sosai.Wannan sau da yawa yakan haifar da cikakken lalata na graphite crucibles bayan da yawa tsari hawan keke, game da shi escalating samar farashin.Bugu da ƙari, ƙaƙƙarfan yanayi suna canza kaddarorin saman abubuwan abubuwan graphite, suna lalata maimaitawa da kwanciyar hankali na aikin samarwa.

Don magance waɗannan ƙalubalen yadda ya kamata, fasahar suturar kariya ta fito azaman mai canza wasa.Rubutun kariya bisa gaTantalum carbide (TaC)an gabatar da su don magance batutuwan lalata kayan aikin graphite da ƙarancin wadatar graphite.Abubuwan TaC suna nuna zafin narke wanda ya wuce 3800°C da juriya na kemikal na musamman.Yin amfani da fasahar tururi (CVD) fasaha,TaC shafitare da kauri har zuwa milimita 35 za'a iya ajiyewa ba tare da matsala ba akan abubuwan graphite.Wannan Layer na kariya ba kawai yana haɓaka kwanciyar hankali na kayan aiki ba har ma yana haɓaka tsawon rayuwar abubuwan graphite, saboda haka rage farashin samarwa da haɓaka ingantaccen aiki.

Semicera, babban mai samar daTaC shafi, ya taimaka wajen kawo sauyi a masana'antar semiconductor.Tare da fasahar yankan-baki da sadaukar da kai ga inganci, Semicera ya baiwa masana'antun semiconductor damar shawo kan ƙalubalen ƙalubale da cimma sabbin nasarori.Ta hanyar ba da suturar TaC tare da aiki mara misaltuwa da aminci, Semicera ya tabbatar da matsayinsa a matsayin amintaccen abokin tarayya ga kamfanonin semiconductor a duk duniya.

A ƙarshe, fasaha mai kariya, mai ƙarfi ta hanyar sabbin abubuwa kamarTaC shafidaga Semicera, yana sake fasalin yanayin yanayin semiconductor da kuma shimfida hanya don ingantacciyar rayuwa mai dorewa nan gaba.
