E makaala! Ke hoʻopaʻa ʻia nei kāu mau mea ʻoki wafer e nā kumu granite substandard?

Ma ke kahua o ka ʻoki ʻana i ka wafer semiconductor, hiki i kahi hewa o 0.001mm ke hoʻolilo i kahi chip hiki ʻole ke hoʻohana. ʻO ke kumu pōhaku koʻikoʻi ʻole, ke kū ʻole kona maikaʻi i nā kūlana, ke koi mālie nei ʻoe i kāu hana i ka ʻaoʻao o ka pilikia kiʻekiʻe a me ke kumukūʻai kiʻekiʻe! Ke lawe pololei nei kēia ʻatikala iā ʻoe i nā pōʻino huna o nā kumu substandard, mālama i ka pololei o ka ʻoki ʻana a me ka hana pono.
ʻO ka "poma ʻike ʻole" o nā kumu granite substandard
1. Holoi thermal deformation: Ka mea pepehi make o ka pololei
Loaʻa i ka granite haʻahaʻa haʻahaʻa kahi coefficient o ka hoʻonui wela. Ma lalo o ke kaiapuni wela o ka ʻoki wafer (a hiki i 150 ℃ ma kekahi mau wahi), hiki ke hoʻololi ʻia o 0.05mm/m! Ma muli o ka deformation thermal o ke kumu i loko o kekahi mea kanu wafer fabrication, ka nui deviation o ka wafers oki i oi aku mamua o ± 5μm, a me ka hookahi-puʻupuʻu helu omo i ka 18%.
2. ʻAʻole lawa ka ikaika o ke kūkulu ʻana: ʻO ke ola lawelawe o nā mea hana ua "halved"
ʻO nā kumu kūpono ʻole me ka haʻahaʻa haʻahaʻa haʻahaʻa ma mua o 2600kg/m³ he 50% ka hōʻemi ʻana i ke kūpaʻa ʻaʻahu a hōʻailona wahaheʻe i ka hiki ke amo. Ma lalo o ka ʻoki pinepine ʻana, hiki ke ʻaʻahu ka ʻili o ke kumu a ʻike ʻia nā micro-cracks i loko. ʻO ka hopena, ua ʻoki ʻia kekahi mau mea ʻoki i ʻelua makahiki ma mua o ka hoʻonohonoho ʻana, a ʻoi aku ka nui o ke kumukūʻai i hoʻokahi miliona.
3. Poor kemika paʻa: Corrosion ua piha me ka pilikia
ʻO ka Granite i kūponoʻole i nā kūlana he nāwaliwali ke kū'ē i ka corrosion. ʻO nā mea ʻakika a me nā mea alkali i loko o ka wai ʻokiʻoki e hoʻopau mālie i ke kumu, ka hopena o ka hoʻohaʻahaʻa ʻana. Hōʻike ka ʻikepili mai kekahi hale hana i ka hoʻohana ʻana i nā kumu haʻahaʻa, ua pōkole ka pōʻaiapili calibration o nā mea hana mai ʻeono mahina a ʻelua mahina, a ua piʻi ʻekolu ke kumukūʻai mālama.
Pehea e ʻike ai i nā pilikia? ʻEhā Nā Manaʻo hoʻāʻo nui Pono ʻoe e heluhelu!
✅ Ho'āʻo Density: High quality granite density ≥2800kg/m³, ma lalo o kēia waiwai ka posity defect;
✅ Coefficient o ka ho'āʻo hoʻonui wela: Noi i kahi hōʻike hōʻike o <8×10⁻⁶/℃, ʻaʻohe "kiʻekiʻe deformation kiʻekiʻe kiʻekiʻe";
✅ Hōʻoia palahalaha: Ana ʻia me ka laser interferometer, pono ka palahalaha ≤±0.5μm/m, inā ʻaʻole hiki ke hoʻololi i ka nānā ʻana;
✅ Hōʻoia hōʻoia mana: E hōʻoia i ka ISO 9001, CNAS a me nā palapala hōʻoia ʻē aʻe, hōʻole i ke kumu "ʻekolu-ʻaʻole".
Hoʻomaka ka mālama pono mai ke kumu!
He mea koʻikoʻi kēlā me kēia ʻoki i ka wafer i ka holomua a i ʻole ka hāʻule ʻole o ka chip. Mai hoʻokuʻu i nā kumu granite substandard e lilo i "pololei" i ka pololei! Kaomi no ka loaʻa ʻana o ka "Wafer Cutting Base Quality Assessment Manual", e ʻike koke i nā pōʻino o nā lako, a wehe i nā hāʻina hana kiʻekiʻe!
