SiC Coated Epitaxial Susceptor wani abu ne mai mahimmanci a cikin sarrafa wafer na semiconductor, musamman a cikin dabarun haɓaka epitaxial kamar MOCVD, CVD, da LPE. Yin aiki azaman mai ɗaukar wafer a cikin ma'aunin zafi da zafi, mai ɗaukar hoto yana tabbatar da tsayayyen matsayi, dumama iri ɗaya, da sarrafawa mara lalacewa, waɗanda ke da mahimmanci don samar da ingantattun yadudduka na epitaxial akan SiC da wafers semiconductor.
Maɓallin Ayyuka a cikin Gudanar da Wafer
1. Madaidaicin Tallafin Wafer
Mai cutarwa yana ba da ingantaccen dandamali don wafers yayin girma epitaxial. Daidaiton girman girmansa da shimfidawar samansa yana rage girman canjin wafer ko nakasawa, yana tabbatar da daidaito iri ɗaya a duk faɗin saman wafer.
2. Ingantaccen Gudanar da Thermal
Tare da graphite tushe da m SiC shafi, mai susceptor hada high thermal watsin tare da m zafi juriya. Wannan yana ba da damar:
● Saurin zagayowar dumama da sanyaya
● Rarraba yawan zafin jiki a cikin wafer
● Ingantattun kula da kauri na epitaxial Layer da bayanan abubuwan da ke kara kuzari
3. Lalacewa & Juriya
A cikin matakai na epitaxial da suka haɗa da iskar gas (NH₃, HCl, Cl₂), murfin SiC yana kare graphite substrate daga yashwa kuma yana hana haɓakar ƙwayoyin cuta. Layin SiC mai tsafta mai tsafta yana tabbatar da tsaftataccen yanayin girma, yana rage lahani na kristal da hatsarori.
4. Tsarin Gudanarwa & Fa'idodin gani
Kaddarorin gani na rufin SiC suna ba da izini don daidaitaccen ma'aunin zafin jiki na tushen infrared da daidaitawar fitarwa, yana ba da gudummawa ga ingantacciyar kulawar tsari da ci gaban epitaxial iri ɗaya.
Kalubale na Fasaha da Ingantawa
Duk da fa'idodinsa, SiC ɗinmu mai ruɓi na epitaxial susceptors suna fuskantar wasu ƙalubalen injiniya:
1. Coating Uniformity - Rufin SiC mara daidaituwa na iya haifar da wuraren zafi ko dumama wafer mara kyau.
● Haɓakawa: Yi amfani da fasaha na ci gaba na CVD-SiC tare da ingantattun sigogin ajiya don cimma babban ƙima da suturar kayan ado.
2. Ƙarshen Ƙarshe – Micro-cracks ko lahani a cikin shafi na iya sakin barbashi a cikin ɗakin tsari.
● Haɓakawa: Aiwatar da dabarun rufe fuska da yawa da duba ƙasa akai-akai don rage haɗari.
3. Rayuwa a Karkashin Yanayi - Ci gaba da bayyanar da zafi mai zafi (> 1600 ° C) da iskar gas masu lalata suna rage tsawon rayuwa.
● Haɓakawa: Yi amfani da kayan shafa na gaba ko dabarun SiC don haɓaka dorewa da tsawaita hawan aiki.
4. Thermal Danniya Management - Daban-daban na haɓaka rates tsakanin graphite substrate da SiC shafi na iya haifar da danniya.
● Haɓakawa: Haɓaka mashin ɗin da kauri don daidaita haɓakar thermal da hana lalata.
Semixlab SiC Coated Epitaxial Susceptor ba kawai mai riƙe da wafer ba ne - babban mai ba da damar haɓakar haɓakar epitaxial mai inganci a cikin masana'antar semiconductor. Ta hanyar magance ƙalubale a cikin suturar daidaituwa, damuwa mai zafi, da sarrafa barbashi, Semixlab yana ba da ingantaccen, mafita mai dorewa wanda ya dace da buƙatun masana'antar semiconductor na gaba. Semixlab na fatan zama abokin tarayya na dogon lokaci a kasar Sin.
