N'ime mmepụta semiconductor, igwe fotolithography bụ ngwaọrụ dị mkpa nke na-ekpebi kpọmkwem nke ibe, ntọala granite, yana ọtụtụ njirimara ya, aghọwo akụkụ dị mkpa nke igwe fotolithography.
Nkwụsi ike nke okpomọkụ: "Ihe nchekwa" megide mgbanwe okpomọkụ
Mgbe igwe fotolithography na-arụ ọrụ, ọ na-emepụta nnukwu okpomọkụ. Ọbụna mgbanwe okpomọkụ nke naanị 0.1℃ nwere ike ibute mgbanwe nke ihe akụrụngwa ma metụta izi ezi nke fotolithography. Oke nke mgbasawanye okpomọkụ nke granite dị oke ala, naanị 4-8 × 10⁻⁶/℃, nke dị ihe dị ka 1/3 nke ígwè na 1/5 nke alloy aluminom. Nke a na-eme ka ntọala granite nwee ike ịnọgide na-enwe nkwụsi ike nha mgbe igwe fotolithography na-arụ ọrụ ogologo oge ma ọ bụ mgbe okpomọkụ gburugburu ebe obibi gbanwere, na-ahụ na nhazi ziri ezi nke ihe anya na ihe owuwu igwe.
Arụmọrụ mgbochi ịma jijiji nke ukwuu: "Ogbo" nke na-amịkọrọ ịma jijiji
N'ụlọ ọrụ mmepụta ihe na semiconductor, ọrụ nke akụrụngwa gbara ya gburugburu na mmegharị nke ndị mmadụ nwere ike ịkpata mkpọtụ. Granite nwere njupụta dị elu na udidi siri ike, ọ nwekwara ihe ndị na-eme ka mmiri daa nke ọma, yana oke mmiri daa nke okpukpu abụọ ruo ise karịa nke ọla. Mgbe a na-ebufe mkpọtụ mpụga na ntọala granite, esemokwu dị n'etiti kristal mineral dị n'ime na-agbanwe ike ịma jijiji ka ọ bụrụ ike okpomọkụ maka mmịpụta, nke nwere ike ibelata ịma jijiji nke ukwuu n'ime obere oge, na-enye igwe fotolithography ohere iweghachi nkwụsi ike ngwa ngwa ma zere ịchaji ma ọ bụ nhazihie nke usoro fotolithography n'ihi ịma jijiji.
Nkwụsi ike kemịkalụ: "Onye Nche" nke Gburugburu Ebe Obibi Dị Ọcha
Ime igwe fotolithography na-abata na njikọ na ọtụtụ ihe ndị ọzọ dị na ígwè, ihe ndị e ji ígwè mee na-adịkwa mfe ire ere ma ọ bụ wepụta ihe ndị dị na ya. Granite nwere mineral dịka quartz na feldspar. O nwere ihe ndị na-eme ka kemịkalụ sie ike ma sie ike iguzogide ire ere. Mgbe e tinyere ya na mmiri acid na alkali, ire ere elu ya pere mpe nke ukwuu. Ka ọ dịgodị, ihe owuwu ya dị oke njọ anaghị emepụta ihe ọ bụla ma ọ bụ uzuzu, na-emezu ihe achọrọ na ụkpụrụ ụlọ nhicha kachasị elu ma na-ebelata ihe ize ndụ nke mmetọ wafer.
Nhazi mgbanwe: "Ihe kachasị mma" maka imepụta ihe nrịbama ziri ezi
A chọrọ ka etinyere ihe ndị dị mkpa nke igwe fotolithography n'elu ebe a na-eji ihe atụ dị elu. Nhazi dị n'ime nke granite bụ otu, ọ dịkwa mfe ịhazi ya nke ọma site na ịcha, ịchacha ya na usoro ndị ọzọ. Nha ya nwere ike iru ≤0.5μm/m, oke elu ya dịkwa Ra bụ ≤0.05μm, nke na-enye ntọala nrụnye ziri ezi maka ihe ndị dị ka anya anya.
Ogologo ndụ na enweghị mmezi: "Ngwaọrụ dị nkọ" maka mbelata ọnụ ahịa
Ma e jiri ya tụnyere ihe ndị e ji ígwè rụọ nke na-eme ka ike gwụ ma gbawaa n'ihi ojiji ogologo oge, granite anaghị enwe mgbanwe plastik ma ọ bụ mgbawa n'okpuru ibu nkịtị, ọ dịghịkwa achọ ọgwụgwọ elu, si otú a na-ezere ihe egwu nke mkpụcha akpụkpọ ahụ na mmetọ. N'ọrụ bara uru, mgbe ejiri ya ruo ọtụtụ afọ, ihe ngosi arụmọrụ dị mkpa nke ntọala granite ka nwere ike ịnọgide na-adịgide, na-ebelata ọnụ ahịa ọrụ na mmezi nke akụrụngwa ahụ.
Site na nkwụsi ike okpomọkụ, iguzogide mkpọtụ ruo na enweghị ike kemịkalụ, ọtụtụ njirimara nke ntọala granite na-emezu ihe achọrọ nke igwe fotolithography. Ka usoro mmepụta chip na-aga n'ihu na-etolite ruo na nkenke ka elu, ntọala granite ga-anọgide na-arụ ọrụ a na-apụghị ịgbanwe agbanwe n'ọhịa nke mmepụta semiconductor.
