Ubwino wosankha maziko a granite patebulo loyesa la semiconductor wafer.

ku
M'makampani a semiconductor, kuyang'ana kwawafa ndi njira yofunika kwambiri yowonetsetsa kuti chip chikuyenda bwino komanso chimagwira ntchito bwino, ndipo kulondola ndi kukhazikika kwa tebulo loyang'anira zimagwira ntchito yofunika kwambiri pakuzindikira. Maziko a granite okhala ndi mawonekedwe ake apadera, khalani chisankho chabwino patebulo loyang'anira zowotcha za semiconductor, zotsatirazi kuchokera pakuwunika kwamitundu yambiri. ku

Choyamba, gawo la chitsimikizo cholondola
1. Ultra-high flatness ndi kuwongoka: Mtsinje wa granite umagwiritsidwa ntchito ndi luso lamakono lamakono, ndipo flatness imatha kufika ± 0.001mm / m kapena ngakhale kulondola kwapamwamba, ndipo kuwongoka ndikwabwino kwambiri. Poyang'anira kachipangizo kakang'ono, ndege yolondola kwambiri imapereka chithandizo chokhazikika cha chofufumitsa ndikuonetsetsa kuti pali kulumikizana kolondola pakati pa kafukufuku wa zida zowunikira ndi zida za solder pamtunda. ku
2. Coefficient yotsika kwambiri yowonjezera kutentha: kupanga semiconductor kumakhudzidwa ndi kusintha kwa kutentha, ndipo coefficient of thermal expansion of granite ndi yotsika kwambiri, kawirikawiri pafupifupi 5 × 10⁻⁶/℃. Pamene nsanja yodziwira ikugwira ntchito, ngakhale kutentha kwapakati kumasinthasintha, kukula kwa maziko a granite kumasintha pang'ono. Mwachitsanzo, mumsonkhano wotentha kwambiri m'nyengo yachilimwe, kutentha kwa chitsulo chodziwika bwino chodziwika bwino kungapangitse kuti malo omwe ali ndi chiwombankhanga ndi zipangizo zodziwira zisinthe, zomwe zimakhudza kulondola; Pulatifomu yodziwira maziko a granite imatha kukhala yokhazikika, kuwonetsetsa kulondola kwa malo ophatikizika ndi zida zodziwikiratu panthawi yozindikira, ndikupereka malo okhazikika kuti azindikire molondola kwambiri. ku
Chachiwiri, gawo lokhazikika
1. Kukhazikika kokhazikika ndi kukana kugwedezeka: Granite pambuyo pa zaka mamiliyoni ambiri a geological process, mkati mwake ndi wandiweyani komanso wofanana. M'malo ovuta a fakitale ya semiconductor, kugwedezeka komwe kumapangidwa ndi kagwiritsidwe ntchito ka zida zotumphukira ndi ogwira ntchito oyenda mozungulira kumachepetsedwa bwino ndi maziko a granite. ku
2. Kugwiritsa ntchito nthawi yayitali: poyerekeza ndi zipangizo zina, granite imakhala ndi kuuma kwakukulu, kukana kuvala mwamphamvu, ndipo kuuma kwa Mohs kumatha kufika 6-7. Pansi pa granite pansi simavalidwa mosavuta panthawi yokweza, kutsitsa ndi kuyang'anira pafupipafupi. Malinga ndi kugwiritsa ntchito ziwerengero zenizeni za data, kugwiritsa ntchito tebulo loyesa m'munsi mwa granite, kugwira ntchito mosalekeza pambuyo pa maola 5000, kukhazikika komanso kuwongoka kutha kusungidwabe kupitirira 98% ya kulondola koyambirira, kuchepetsa zida chifukwa cha kuvala kwa maziko omwe amachititsidwa ndi kuwongolera pafupipafupi komanso kukonza nthawi, kuchepetsa ndalama zoyendetsera bizinesi, kutsimikizira kukhazikika kwanthawi yayitali kwa ntchito. ku

Chachitatu, choyera komanso chotsutsana ndi kusokoneza
1. Kutulutsa fumbi lochepa: malo opangira semiconductor ayenera kukhala oyera kwambiri, ndipo zinthu za granite zokha zimakhala zokhazikika komanso zosavuta kupanga fumbi. Panthawi yogwiritsira ntchito nsanja yoyesera, fumbi lopangidwa ndi maziko limapewedwa kuti liwononge chofufumitsa, ndipo chiopsezo chafupipafupi ndi dera lotseguka lomwe limayambitsidwa ndi fumbi limachepetsedwa. M'dera loyang'anira zowombera pamalo opanda fumbi, fumbi lozungulira patebulo loyang'anira maziko a granite limayendetsedwa nthawi zonse mpaka lotsika kwambiri, kukwaniritsa zofunikira zaukhondo zamakampani a semiconductor. ku
2. Palibe kusokoneza maginito: zida zowunikira zimakhudzidwa ndi chilengedwe cha electromagnetic, ndipo granite ndi zinthu zopanda maginito, zomwe sizidzasokoneza chizindikiro chamagetsi cha zipangizo zowunikira. Pogwiritsa ntchito kuzindikira kwa mtengo wa ma elekitironi ndi matekinoloje ena oyesera omwe amafunikira malo okwera kwambiri amagetsi, maziko a granite amatsimikizira kufalikira kokhazikika kwa siginecha yamagetsi pazida zowunikira ndikuwonetsetsa kulondola kwa zotsatira zoyesa. Mwachitsanzo, chiwombankhanga chikayesedwa kuti chikhale cholondola kwambiri, chopanda maginito cha granite maziko chimapewa kusokoneza ma siginecha apano ndi ma voltage, kotero kuti zodziwikiratu zimawonetsa mawonekedwe amagetsi a wafer.
