Chenjerani! Kodi zida zanu zodulira zophatikizika zikubwezeretsedwa ndi maziko a granite otsika?

Pankhani yodula semiconductor wafer, cholakwika cha 0.001mm chingapangitse kuti chip zisagwiritsidwe ntchito. Maziko a granite omwe akuwoneka ngati osafunikira, pomwe mtundu wake umalephera kukwaniritsa miyezo, ndikukankhira mwakachetechete kupanga kwanu pachiwopsezo chachikulu komanso mtengo wokwera! Nkhaniyi imakufikitsani mwachindunji ku zoopsa zobisika za maziko osakhazikika, kuteteza kulondola kwa kudula komanso kupanga bwino.
"Bomba losaoneka" la maziko a granite otsika
1. Thermal deformation: Wakupha wakupha wolondola
Granite yotsika kwambiri imakhala ndi coefficient yochulukirapo pakukulitsa kutentha. Pansi pa kutentha kwapamwamba kwa kudula kwa wafer (mpaka 150 ℃ m'madera ena), imatha kupindika ndi 0.05mm/m! Chifukwa cha kutenthedwa kwa maziko pachomera china chopangira chophatikizika, kupatuka kwa zowotcha zodulidwa kudapitilira ± 5μm, ndipo kuchuluka kwa zidutswa za batch imodzi kudakwera mpaka 18%.
2. Mphamvu zosakwanira zamapangidwe: Moyo wautumiki wa zida ndi "theka"
Maziko osayenerera okhala ndi kachulukidwe otsika kuposa 2600kg/m³ ali ndi kutsika kwa 50% pakusavala komanso kulembedwa molakwika kunyamula katundu. Pansi pa kugwedezeka kwafupipafupi, pamwamba pa mazikowo ndi osavuta kuvala ndipo ming'alu yaying'ono imawonekera mkati. Zotsatira zake, zida zina zodulira zidathetsedwa zaka ziwiri pasadakhale nthawi yake, ndipo mtengo wosinthira zidapitilira miliyoni imodzi.
3. Kusakhazikika kwamankhwala: Zimbiri zimakhala zowopsa
Granite yomwe sikugwirizana ndi miyezo imakhala ndi kukana kofooka kwa dzimbiri. Zigawo za asidi ndi alkali m'madzi odulira zimawononga pang'onopang'ono maziko, zomwe zimapangitsa kuwonongeka kwa flatness. Deta yochokera ku labotale ina ikuwonetsa kuti pogwiritsa ntchito maziko ocheperako, nthawi yosinthira zida yafupikitsidwa kuchoka pa miyezi isanu ndi umodzi mpaka miyezi iwiri, ndipo mtengo wokonzanso wakwera katatu.
Kodi kudziwa zoopsa? Mfundo Zinayi Zoyesera Zomwe Muyenera Kuwerenga!
✅ Mayeso a kachulukidwe: Kuchuluka kwa granite kwapamwamba kwambiri ≥2800kg/m³, pansi pa chilema cha porosity ichi chikhoza kukhalapo;
✅ Coefficient of thermal expansion test: Funsani lipoti loyesa <8×10⁻⁶/℃, palibe "mfumu yopindika kutentha kwambiri";
✅ Kutsimikizika kwa flatness: Kuyezedwa ndi laser interferometer, flatness iyenera kukhala ≤± 0.5μm/m, apo ayi, kudula kumakonda kusuntha;
✅ Chitsimikizo chovomerezeka: Tsimikizirani ISO 9001, CNAS ndi ziphaso zina, kukana maziko a "atatu-ayi".
Kuteteza kulondola kumayambira pansi!
Kudula kulikonse pamkate ndikofunikira kuti chip chipambane kapena kulephera. Osalola kuti maziko a granite otsika kukhala "chopunthwitsa" molondola! Dinani kuti mupeze "Wafer Cutting Base Quality Assessment Manual", nthawi yomweyo zindikirani zoopsa za zida, ndikutsegula njira zopangira zolondola kwambiri!
