Mgbanwe dị na izi ezi nke ịkpụ wafer! Kedu otu esi edozi ọnọdụ ±5um maka ntọala granite?

N'ọgụ kachasị elu nke "nanoprecision" na mmepụta semiconductor, ọbụna obere mmejọ dị na ngwa ịkpụ wafer nwere ike ime ka mgbawa ghọọ ihe efu. Ntọala granite bụ dike a na-akpọghị aha nke na-achịkwa izi ezi nke ọnọdụ ±5um ugboro ugboro, na-edegharị iwu nke imepụta ihe ziri ezi na ihe ebube atọ sitere n'okike ya.

"Akpịsị na-eme ka ihe sie ike" megide mgbanwe okpomọkụ: Oke nke mgbasawanye okpomọkụ nke granite dị ala dịka 5-7 × 10⁻⁶/℃, nke bụ naanị otu ụzọ n'ụzọ atọ nke ihe ígwè. N'okpuru mmetụta okpomọkụ nke ọrụ ngwa ngwa nke ngwa ịkpụ wafer na-emepụta, ihe nkịtị ga-agbanwe n'ihi mmụba okpomọkụ na mkpụkọ, na-eme ka ọnọdụ nke isi ịkpụ ahụ gbanwee. Agbanyeghị, ntọala granite nwere ike ịnọgide na-enweghị mmegharị, na-ewepụ mgbanwe ọnọdụ nke mgbanwe okpomọkụ kpatara ma na-etinye ntọala siri ike maka nkenke.

"Ọta nkịtị" nke mmịpụta mkpọtụ: A pụrụ iwere mkpọtụ mgbe niile nke ngwaọrụ igwe na mkpọtụ na-aga n'ihu nke akụrụngwa n'ebe a na-arụ ọrụ dị ka "ihe na-egbu egbu" ruo n'ókè ziri ezi. Ọdịdị kristal pụrụ iche nke granite dị ka ihe na-amịkọrọ ihe mberede eke, nke nwere ike ịgbanwe ngwa ngwa mkpọtụ mpụga na mkpọtụ igwe nke ọrụ akụrụngwa na-emepụta ka ọ bụrụ ike okpomọkụ maka mmịpụta. Ọ bụ ezie na ntọala ndị ọzọ ka "na-ama jijiji" n'ihi ịma jijiji, ntọala granite emepụtala ikpo okwu kwụsiri ike maka isi ihe na-egbutu nke na-anọgide na-enweghị mmegharị, na-eme ka izi ezi nke ±5um kwe omume.

"Ebe E Wusiri Ike Ebighị Ebi" nke na-anaghị emebi emebi: Ụlọ ọrụ semiconductor juputara na ihe ndị na-emebi emebi dịka ihe ngwọta etching na ihe nhicha acid na alkali. N'ebe dị otú ahụ, ntọala ígwè ga-eji nwayọọ nwayọọ nchara ma gbanwee. Granite, ya na nkwụsi ike kemịkalụ ya, anaghị emeghachi omume na ihe kemịkalụ ndị a ma ọlị. N'agbanyeghị afọ ole e ji ya mee ihe, ọ nwere ike ịnọgide na-eguzosi ike n'ihe ma na-ahụ na e ji ya mee ihe nke ọma.

Site na nkà ihe onwunwe ruo na nhazi nke ọma, ntọala granite egosila na ọ bụghị ihe niile nwere ike ịnagide nsogbu siri ike nke imepụta semiconductor. Ọ bụ kpọmkwem n'ihi uru ndị a na-apụghị ịgbanwe agbanwe ka ntọala granite aghọwo isi ihe maka ngwa ịkpụ wafer iji nweta izi ezi nke ọnọdụ ±5um, ma meekwa ka ụlọ ọrụ semiconductor na-aga n'ihu na-aga n'ihu na nkenke ka mma!
