Itonde! Ese ibikoresho byawe byo gukata wafer biri mu kato gafite ishingiro ritujuje ubuziranenge bwa granite?

Mu rwego rwo gukata wafer ya semiconductor, ikosa rya 0.001mm rishobora gutuma chip idakoreshwa. Ishingiro rya granite risa n'aho ridafite agaciro, iyo ubuziranenge bwaryo bunaniwe kuzuza ibisabwa, ririmo gutuma umusaruro wawe ugera ku ntera ikomeye kandi ihenze cyane! Iyi nkuru irakujyana mu kaga gahishe k'ibice bidafite ubuziranenge, ikarinda uburyo bwo gukata neza no gukora neza.
"Igisasu kitagaragara" cy'ibirindiro bya granite bidafite ireme
1. Guhindura ubushyuhe mu buryo butunguranye: Uburyo butuma umuntu yica uburyohe
Granite y’ubuziranenge buke ifite ubushobozi bukabije bwo kwaguka k’ubushyuhe. Mu gihe cy’ubushyuhe bwinshi bwo gukata wafer (kugeza kuri 150℃ mu duce tumwe na tumwe), ishobora guhinduka 0.05mm/m! Bitewe n’ubushyuhe bw’ishingiro mu ruganda runaka rukora wafer, ingano y’udupira twaciwe yarenze ± 5μm, kandi igipimo cy’udupira tw’ibumba rimwe cyazamutse kigera kuri 18%.
2. Ingufu zidahagije mu miterere: Igihe cyo gukoresha ibikoresho "kigabanijwemo kabiri"
Ibyuma bidafite ubucucike buri munsi ya 2600kg/m³ bigabanya 50% mu kwangirika no kwihanganira gutwara imizigo. Mu gihe cyo gukata kenshi, ubuso bw'ibyuma bushobora kwangirika kandi imbere hakagaragara uduce duto. Kubera iyo mpamvu, ibikoresho bimwe na bimwe byo gukata byakuweho imyaka ibiri mbere y'igihe cyari giteganyijwe, kandi ikiguzi cyo gusimbuza cyarenze miliyoni imwe.
3. Kudakomera neza mu binyabutabire: Ingese yuzuyemo akaga
Granite itujuje ibisabwa ifite ubushobozi bwo kudakira ingese. Ibice bya aside na alkali biri mu mazi acibwa bizagenda bigabanya ishingiro buhoro buhoro, bigatuma ritagorama. Amakuru aturuka muri laboratwari imwe agaragaza ko hakoreshejwe ishingiro ridafite ingufu, igihe cyo gupima ibikoresho cyagabanijwe kuva ku mezi atandatu kugera ku mezi abiri, kandi ikiguzi cyo kubungabunga cyiyongereyeho gatatu.
Ni gute wamenya ingaruka mbi? Ingingo enye z'ingenzi ugomba gusoma mu isuzuma!
✅ Ikizamini cy'ubucucike: Ubucucike bwa granite bwiza cyane ≥2800kg/m³, ubusembwa bw'umuyoboro munsi y'ubu bunini bushobora kubaho;
✅ Ikizamini cyo kwagura ubushyuhe: Saba raporo y'ikizamini cya < 8×10⁻⁶/℃, nta "king cy'ubushyuhe bwinshi";
✅ Igenzura ry'ubugari: Bipimwe hakoreshejwe interferometer ya laser, ubugari bugomba kuba ≤±0.5μm/m, bitabaye ibyo icyitonderwa cyo gukata gishobora guhinduka;
✅ Igenzura ry’impamyabushobozi yemewe: Emeza ISO 9001, CNAS n’izindi mpamyabushobozi, uhakane ishingiro rya "nta mpushya eshatu".
Uburinzi buhamye buhera ku gice cyo hasi!
Buri gice cyose cyaciwe kuri wafer ni ingenzi kugira ngo chip igende neza cyangwa ihombe. Ntureke ngo ishingiro rya granite ridafite ubuziranenge ribe "inzitizi" ku buryo bunoze! Kanda kugira ngo ubone "Igitabo cy'Isuzuma ry'Ubuziranenge bw'Ishingiro rya Wafer Cutting", hita umenya ingaruka z'ibikoresho, kandi ufungure ibisubizo byo gukora neza cyane!
