Kedu ihe bụ Isostatic Graphite Crucible dị ọcha nke ukwuu?

Igwe Graphite Isostatic dị ọcha nke dị elu bụ akpa e ji ihe graphite isotropic mepụta site na usoro ịpị isostatic. Ma e jiri ya tụnyere ngwaahịa graphite a kpụrụ akpụ, graphite isostatic na-enye:

● Ọdịdị obere ihe dị n'otu n'akụkụ niile

● Ike dị elu na ike igwe

● Ọkwa okpomọkụ dị elu nke ukwuu

● Ezigbo iguzogide okpomọkụ ujo

● Obere porosity

● Ọdịnaya adịghị ọcha nke ukwuu

Mgbe e sachara ya nke ọma, a na-achịkwa ntụ dị n'ime ya n'okpuru 5 ppm, ebe ụfọdụ ihe ndị e ji semiconductor mee na-eru ọkwa adịghị ọcha n'okpuru 3 ppm.

Ọrụ dị na Mmepụta Semiconductor

N'ime uto kristal Silicon Carbide (SiC) site na iji usoro Physical Vapor Transport (PVT), gricibles graphite na-arụ ọrụ dị ka arịa ihe nchekwa ihe na akụkụ dị mkpa nke sistemụ ubi okpomọkụ. Na-arụ ọrụ na okpomọkụ na-agafekarị 2,200°C, gricible ga-anọgide na-enwe nkwụsi ike nha ebe ọ na-akwado nhazi okpomọkụ ziri ezi dị mkpa maka mbufe uzuoku na nhazi kristal. Ịdị ọcha na nhazi isotropic nke graphite na-emetụta kpọmkwem njikọta adịghị ọcha, nkesa okpomọkụ, ọnụego uto kristal, na mmepụta ntụpọ.

Ọrụ nke High-Purity Isostatic Graphite Crucibles gafere mmepụta SiC gaa na teknụzụ uto kristal Gallium Nitride (GaN) dị elu. Ma ejiri ya na HVPE, mmụba flux, ma ọ bụ ụzọ mmepụta kristal buru ibu na-apụta, griitị graphite na-enye gburugburu ebe okpomọkụ dị elu nke na-akwado njem ihe na nhazi kristal ma na-ebelata ihe egwu mmerụ ahụ.

N'ime mmepụta ihe epitaxial nke semiconductor, gụnyere SiC epitaxy, uto kristal AlN, na nhazi semiconductor dị elu, griitị graphite na-enye aka na nhazi okpomọkụ na imeghachi usoro. Ọdịdị okpomọkụ ha dị mma na iguzogide ujo okpomọkụ na-eme ka ọrụ kwụsie ike n'okpuru ọnọdụ usoro dị oke njọ, na-akwado njikwa ziri ezi nke uzuoku, sublimation, na usoro itinye ihe.

Igwe Isostatic Graphite dị elu na-arụkwa ọrụ dị mkpa n'ịmepụta ihe seramiiki dị elu na ntụ semiconductor nke ọgbọ nke atọ. N'oge a na-eme ka silicon carbide, aluminum nitride, boron nitride, na seramiiki ndị ọzọ dị elu sie ike, ihe mkpuchi ahụ na-enye gburugburu ebe obibi siri ike ma dịkwa ka nke kemịkalụ nke na-akwalite njupụta ebe ọ na-ebelata mmetọ. Mmezi ndị a na-enweta na ịdị ọcha ihe, njikwa okpomọkụ, na arụmọrụ igwe dị oke mkpa maka ngwa sitere na akụkụ akụrụngwa semiconductor ruo na nkwakọ ngwaahịa eletrọniki dị elu.

Ngwa semiconductor n'ọdịnihu chọrọ ọkwa adịghị ọcha n'okpuru 5 ppm, na, n'ọnọdụ ụfọdụ, ịbịaru nso 1 ppm iji kwado nnukwu nha kristal na obere njupụta ntụpọ.

Teknụzụ mkpuchi

A na-etinye ihe mkpuchi elu dị elu na graphite crucibles, gụnyere:

● Mkpuchi Silicon Carbide (SiC)

● Mkpuchi Tantalum Carbide (TaC)

● Mkpuchi Pyrolytic Carbon (PyC)

Ihe mkpuchi ndị a na-eme ka ahụ dịkwuo mma:

● Mgbochi ire ere

● Ịkwụsi ike na okpomọkụ

● Arụmọrụ ndụ niile

● Ịdị ọcha nke usoro

● Nhazi Crucible Karịrị Ukwuu

Azụmahịa nke:

● Wafer SiC nke dị sentimita asatọ

● Ihe ndị buru ibu karịa GaN

● Ihe ndị dị elu maka semiconductor ike
