SiC Coated Isostatic Graphite Crucible

SiC Coated Isostatic Graphite Crucible e fanoang ke Semixlab e entsoe ka graphite ea premium isostatic, e tsejoang ka bongata ba eona bo lekaneng, sebopeho se setle sa lijo-thollo, le matla a ikhethang a mochine tlas'a maemo a feteletseng. Seaparo sa silicon carbide (SiC) se nang le bohloeki bo phahameng ba Chemical Vapor Deposition (CVD) se sebelisoa holim'a graphite, se etsa lesela le teteaneng le le sireletsang le matlafatsang haholo ho hanyetsa oxidation, botsitso ba mocheso le ho se sebetse ha lik'hemik'hale. Motsoako ona o tsoetseng pele oa thepa o tiisa hore ho na le conductivity e phahameng ea mocheso, tšilafalo e fokotsehileng, bophelo bo atolositsoeng ba tšebeletso, le ts'ebetso e tsitsitseng tlas'a maemo a ts'ebetso ea semiconductor ea mocheso o phahameng haholo.

Sebopeho sa Boitsebiso le Thepa

Crucible ea rona e entsoe ka lisebelisoa tse peli tsa bohlokoa:

·Isostatic Graphite Substrate: Boitsebiso bona ba motheo bo hlahisoa ka mokhoa oa ho hatella oa isostatic, o tiisang hore ho na le sebopeho se ts'oanang, se phahameng se nang le matla a ikhethang a mochine le botsitso ba mocheso. Sebopeho sena sa isotropic se bolela hore thepa ea eona e tsitsitse ka mahlakoreng 'ohle, e thibela ho loana le ho phunyeha le tlas'a libaesekele tse chesang haholo. Graphite e hloekileng haholo eo re e sebelisang e fokotsa litšila, e leng ea bohlokoa bakeng sa ho thibela tšilafalo mekhoeng e hlokolosi ea semiconductor.

· Silicon Carbide(SiC) Coating: E sebelisoa ho sebelisoa mokhoa o tsoetseng pele oa Chemical Vapor Deposition (CVD), lesela la SiC le etsa mokoallo o teteaneng, o se nang porous o sireletsang.

Karolo ea Ts'ebetso Mekhoeng ea Semiconductor

1. Khōlo ea SiC Crystal (Mokhoa oa PVT)

Ka mokhoa oa Physical Vapor Transport (PVT) bakeng sa kholo ea kristale ea SiC, crucible e bapala karolo ea makhaola-khang ho finyella tlhahiso ea boleng bo phahameng ba kristale. Sebaka se koahetsoeng ke SiC se fana ka tikoloho e tsitsitseng ea lik'hemik'hale e thibelang liketso tse sa batleheng pakeng tsa substrate ea graphite le lisebelisoa tse tala tsa mohloli oa SiC. Sena se fokotsa tšilafalo ea khabone le ho ntlafatsa ho tšoana ha lesela la kristale. The crucible's superior thermal conductivity etsa bonnete ba kabo e tsitsitseng ea mocheso, e leng ea bohlokoa bakeng sa ho laola likhahla tsa mocheso le ho fokotsa sets'oants'o sa dislocation ka har'a liboule tsa SiC. Ka lebaka leo, crucible e kenya letsoho ka ho toba ho ntlafatso ea lihlahisoa tsa kristale le boleng ba liphaephe bakeng sa tlhahiso ea lisebelisoa tsa semiconductor tse tlase.

2. silicon e le 'ngoe Khōlo ea Crystal

Nakong ea ts'ebetso ea kholo ea kristale e le 'ngoe ea silicon (joalo ka mokhoa oa Czochralski), crucible e tlameha ho mamella ho pepesehela mocheso o phahameng haholo ha e ntse e boloka lik'hemik'hale. Ho roala ha SiC ho sebetsa e le thibelo e sireletsang khahlanong le oxidation le ho hasana ha litšila, ho netefatsa hore ha ho na tšilafalo e fallelang ka har'a silicon e qhibilihisitsoeng. Sena se fella ka likristale tsa silicon tse hloekileng haholo tse nang le mefokolo e fokolang ea sebopeho, e leng bohlokoa bakeng sa ho etsa li-IC tse tsoetseng pele, lisebelisoa tsa motlakase le lisele tsa photovoltaic. Ho feta moo, ho roala ho ntlafatsa bophelo ba ts'ebeletso ea crucible, ho fokotsa khafetsa le litšenyehelo tsa tlhahiso ka kakaretso.

3. Phekolo ea Mocheso o Phahameng oa Mocheso le Mekhoa ea Phatlalatso

Kalafong ea mocheso, ho kenya le ho hasana, liphaephe tsa semiconductor li pepesetsoa mocheso o phahameng moo bohloeki le botsitso li leng bohlokoa haholo. SiC-coated crucible e fana ka khanyetso e ntle khahlanong le sublimation le outgassing, e thibelang tlhahiso ea likaroloana e ka senyang bokaholimo ba liphaephe. Botsitso ba eona ba mocheso bo tiisa maemo a ho futhumatsa a ts'oanang, a ts'ehetsang phallo e nepahetseng ea dopant le ts'ebetso e tsitsitseng ea wafer. Ka ho boloka sepakapaka se hloekileng sa ts'ebetso le ho fokotsa ho senyeha ha thepa, crucible e thusa bahlahisi ho fumana li-wafers tse tšepahalang, tse se nang sekoli tlhahisong e kholo.

Melemo ea Semixlab

Semixlab e hlahella e le morekisi ea tšepahalang ka ho kopanya boenjiniere bo nepahetseng le netefatso e tiileng ea boleng. SiC Coated Graphite Crucible e 'ngoe le e 'ngoe e etsa liteko tse matla tsa fektheri ho netefatsa ho khomarela, ho lekana ka botenya, le ts'ebetso tlas'a baesekele e futhumetseng. Khamphani e fana ka litharollo tse ikhethileng, ho lokisa litekanyo tsa crucible, botenya ba ho roala, le thepa ea bokaholimo ho fihlela litlhoko tse ikhethileng tsa ts'ebetso.

Ntle le tlhahiso, Semixlab e boetse e fana ka lipuisano tsa tekheniki le ts'ehetso ea ts'ebeliso, e thusa baenjiniere ba semiconductor le lihlopha tsa ho reka thepa ho khetha moralo o nepahetseng ka ho fetisisa oa crucible bakeng sa maemo a bona a ts'ebetso. Ka boitlamo ba eona bo matla ba boleng le boits'oaro, Semixlab e netefatsa phepelo e tšepahalang le ts'ebetso ea nako e telele bakeng sa tlhahiso e tsoetseng pele ea semiconductor.
