Likepe tsa Graphite, tse tsejoang hape e le likepe tsa graphite, li bapala karolo ea bohlokoa lits'ebetsong tse rarahaneng tsa tlhahiso ea liserami tsa semiconductor. Likepe tsena tse ikhethileng li sebetsa e le lijari tse tšepahalang bakeng sa li-wafer tsa semiconductor nakong ea kalafo ea mocheso o phahameng, li netefatsa ts'ebetso e nepahetseng le e laoloang. Ka litšobotsi tsa tsona tse ikhethang le lits'ebetso tse feto-fetohang,Likepe tsa graphiteli fetohile lisebelisoa tsa bohlokoa indastering ea semiconductor. A re hlahlobeng likarolo tsa bohlokoa tse etsangLikepe tsa graphitedikarolo tsa bohlokwa tlhahisong ya diserame tsa semiconductor.
1. Mamello ea Mocheso o Phahameng:
Likepe tsa graphiteli entsoe ka thepa ea boleng bo holimo ea graphite e tsebahalang ka ho hanyetsa mocheso ka tsela e ikhethang. Tšobotsi ena e lumella likepe tsa Graphite ho mamella mocheso o feteletseng o kopanang le oona nakong ea lits'ebetso tsa tlhahiso ea semiconductor, joalo ka chemical vapor deposition (CVD) le silicon carbide coating. Bokhoni ba ho boloka botsitso ba sebopeho le botsitso ba boholo tlas'a maemo a mocheso o matla bo bohlokoa bakeng sa ho netefatsa tlhahiso ea semiconductor e tsitsitseng le e tšepahalang.
2. Ho se sebetse hantle ha lik'hemik'hale:
Graphite, thepa ea mantlha e sebelisitsoeng hoLikepe tsa graphite, e bontša ho se sebetse hantle ha lik'hemik'hale, e leng se etsang hore e hanele mafome le lik'hemik'hale. Tšobotsi ena e molemo haholo tlhahisong ea liserame tsa semiconductor, moo lik'hemik'hale tse matla le likhase tse arabelang hangata li sebelisoang. Likepe tsa graphite li fana ka tikoloho e sireletsang bakeng sa li-wafer tsa semiconductor, e thibelang tšilafalo le ho netefatsa bohloeki ba sehlahisoa sa ho qetela.
3. Taolo e Nepahetseng ea Litekanyo:
Likepe tsa graphiteLi entsoe ka nepo ho amohela li-wafer tsa semiconductor tsa boholo le libopeho tse fapaneng. Meralo ea tsona e ka fetoloang e lumella taolo e nepahetseng ea litekanyo, e netefatsa hore li lekana hantle bakeng sa li-wafer le ho fokotsa kotsi ea tšenyo nakong ea ho sebetsana le ho sebetsana le tsona. Boemo bona ba ho nepahala bo bohlokoa bakeng sa ho fihlela botenya bo tšoanang ba ho roala le ho nepahala ha ho beoa lits'ebetsong tsa tlhahiso ea li-semiconductor.
4. Ho Feto-fetoha ha Ditshebediso:
Likepe tsa graphitee sebelisoa haholo lits'ebetsong tse fapaneng tsa tlhahiso ea semiconductor, ho kenyeletsoa epitaxy, diffusion, annealing, le thin-film deposition. Ebang ke ho tšehetsa li-wafer tsa silicon nakong ea ts'ebetso ea mocheso kapa ho thusa kholo ea likarolo tsa epitaxial, likepe tsa Graphite li fana ka mekhoa e fapaneng le ts'epahalo lits'ebetsong tse fapaneng. Bokhoni ba tsona ba ho mamella ho pepesehela mocheso o phahameng nako e telele le libaka tse senyang li li etsa lisebelisoa tsa bohlokoa tlhahisong ea li-ceramic tsa semiconductor.
5. Ho lumellana ha Silicon Carbide Coating:
Likepe tsa graphite li loketse hantle lits'ebetsong tse kenyeletsang lipehelo tsa silicon carbide (SiC), karolo ea bohlokoa lisebelisoa tse tsoetseng pele tsa semiconductor. Ho lumellana ha graphite le silicon carbide ho nolofalletsa ho beoa ha SiC ka mokhoa o sebetsang le o ts'oanang holim'a li-substrate tsa semiconductor, ho ntlafatsa ts'ebetso ea sesebelisoa le ts'epo. Likepe tsa graphite li bapala karolo ea bohlokoa ho nolofatseng ts'ebetso ea ho beoa, ho netefatsa ho koaheloa ka mokhoa o ts'oanang le taolo e nepahetseng holim'a botenya ba ho beoa.
Qetellong, likepe tsa Graphite li sebetsa e le likarolo tsa bohlokoa tlhahisong ea liserame tsa semiconductor, li fana ka motsoako o ikhethang oa mamello ea mocheso o phahameng, ho se sebetse ha lik'hemik'hale, taolo e nepahetseng ea litekanyo, le ho lumellana le liphahlo tsa carbide tsa silicon. Ho tenyetseha ha tsona le ho tšepahala ha tsona li li etsa lisebelisoa tsa bohlokoa bakeng sa lits'ebetso tsa tlhahiso ea semiconductor, ho nolofalletsa tlhahiso ea lisebelisoa tsa semiconductor tsa boleng bo holimo le tse sebetsang hantle. Ha theknoloji ea semiconductor e ntse e tsoela pele, likepe tsa Graphite li tla lula e le matlotlo a bohlokoa, li khanna boqapi le tsoelo-pele indastering ea semiconductor.
