Ọnọdụ ọhụrụ na ụlọ ọrụ Semiconductor: Ngwa nke teknụzụ mkpuchi mkpuchi

Ụlọ ọrụ semiconductor na-ahụ ọganihu na-enwetụbeghị ụdị ya, karịsịa na mpagharasilicon carbide (SiC)ike eletrọnịkị. Na ọtụtụ nnukwu-ọnụ ọgụgụwaferA na-ewu ụlọ ma ọ bụ mgbasawanye iji gboo mkpa na-arịwanye elu nke ngwaọrụ SiC na ụgbọ ala eletrik, ọganihu a na-enye ohere dị ịrịba ama maka uto uru. Otú ọ dị, ọ na-ewetakwa ihe ịma aka pụrụ iche na-achọ ngwọta ọhụrụ.

N'ime obi nke ịba ụba nke mgbawa SiC zuru ụwa ọnụ bụ imepụta kristal SiC dị elu, wafers na akwa epitaxial. Ebe a,semiconductor-ọkwa graphiteihe na-arụ ọrụ dị mkpa, na-eme ka uto SiC kristal na ntinye nke ọkwa SiC epitaxial. Mkpuchi ọkụ na inertness nke Graphite na-eme ka ọ bụrụ ihe kacha amasị, nke ejiri ya na crucibles, pedestals, disks planetary, na satịlaịtị n'ime uto kristal na sistemụ epitaxy. Ka o sina dị, ọnọdụ usoro ahụ siri ike na-ebute nnukwu ihe ịma aka, na-eduga n'ibelata ngwa ngwa nke ihe ndị dị na graphite ma mechaa gbochie mmepụta nke kristal SiC dị elu na akwa epitaxial.

Mmepụta kristal silicon carbide na-agụnye ọnọdụ usoro siri ike, gụnyere okpomọkụ karịrị 2000 Celsius C yana ihe gas na-emebi emebi. Nke a na-ebutekarị mbibi zuru oke nke graphite crucibles mgbe ọtụtụ usoro usoro, si otú ahụ na-abawanye ọnụ ahịa mmepụta. Na mgbakwunye, ọnọdụ ndị siri ike na-agbanwe njiri elu nke akụrụngwa graphite, na-emebi nkwughachi na nkwụsi ike nke usoro mmepụta.

Iji luso ihe ịma aka ndị a ọgụ nke ọma, teknụzụ mkpuchi mkpuchi apụtala dị ka ihe na-agbanwe egwuregwu. Ihe mkpuchi mkpuchi dabere naTantalum carbide (TaC)ewebatala iji leba anya n'okwu nke mmebi akụrụngwa graphite na ụkọ ọkọnọ graphite. Ihe TaC na-egosipụta okpomọkụ na-agbaze karịa 3800 Celsius yana nguzogide kemịkalụ pụrụ iche. Na-eji teknụzụ vapor deposition (CVD) eme ihe,Ihe mkpuchi TaCnwere oke ruru 35 millimeters nwere ike idobe ya n'enweghị nsogbu na akụrụngwa graphite. Igwe nchekwa a abụghị naanị na-akwalite nkwụsi ike ihe kamakwa ọ na-agbatịkwu ogologo ndụ nke akụrụngwa graphite, n'ihi ya na-ebelata ọnụ ahịa mmepụta yana ịkwalite arụmọrụ arụmọrụ.

Semicera, onye na-eweta iheIhe mkpuchi TaC, enyerela aka n'ịgbanwe ụlọ ọrụ semiconductor.
