Soo saarista qalabka semiconductor-ka casriga ah iyo wax soo saarka semiconductor-ka isku-dhafka ah ee jiilka saddexaad (sida Silicon Carbide [SiC] iyo Gallium Nitride [GaN]), doodaha warshadaha badanaa waxay ku saabsan yihiin mashiinnada lithography-ga ee EUV ee aadka u horumarsan, qalabka wax lagu dhejiyo ee plasma, ama nadiifinta gaaska ee horudhaca ah. Si kastaba ha ahaatee, gudaha jawiga aadka u nadiifsan, aadka u daxalaysan, iyo heerkulka sare ee qolka falcelinta waxaa ku jira geesi muhiim ah oo aan la ilaawi karin: susceptor-ka Graphite.
1. Waa maxay Susceptor Graphite?
A Sumeeyaha Garaafigawaa qayb side shaqeyneed oo si sax ah loo farsameeyay oo laga sameeyay garaafit iso-modified ama extruded saafi ah, oo badanaa leh qaab saxan, jeebab leh, ama gaar ahJoomatari saddex-cabbir ah oo loogu talagalay inay ku habboonaadaan qolalka falcelinta gaarka ah.
Qalabka sida Kaydinta Uumiga Kiimikada (CVD), Kaydinta Uumiga Kiimikada ee Birta-Organic (MOCVD), iyo Falaadhaha Habaynta Kuleylka Degdegga ah (RTP), shaqada ugu weyn ee goobta side-ka waa inay si ammaan ah u qabato wafer-yada semiconductor-ka iyadoo u adeegaysa sidii beddelaha kulaylka aasaasiga ah.
