PFA Lining Sheets

Raw Materials: DuPont PFA resin (USA), yakagadzirwa muKirasi 10,000 yakachena workshop kuti ive nechokwadi chekuchena kwepamusoro kweLining Sheet (inochinjika kune semiconductor{2}}giredhi zvinodiwa).
Maitiro: RANA inogadzira mu9,000㎡ PPB/PPT-level yakachena workshop uye inotora "hot-press melting" maitiro ekuumbwa kwakabatana, kudzivirira kusvibiswa kwechikamu panguva yekugadzira uye kuve nechokwadi kuchena kweiyo lining Sheet.

Musimboti: Hunhu hwePFA hunoita kuti ive "high kuchena + high corrosion resistance" inoita kuti ive iyo inofarirwa simbi yekugadzira semiconductor yakakwirira-yakachena, kudzivirira kusvibiswa nesimbi ion pamidziyo (semuenzaniso, electronic-giredhi rehydrogen peroxide) uye kuona kuti goho rinodzika pasi pemvura.
Zvakanakira: Yakasimbiswa neSMIC, iyoion yesimbi iri Ishoma pane kana kuenzana ne0.05ppb mushure mekuchengetedza electronic{{1}giredhi rehydrogen peroxide (industry standard 0.1ppb), ine tembiricha inorambira ye -200℃kusvika 260℃. Senhengo yeChina Semiconductor Indasitiri Association, chigadzirwa chapfuura zvitupa zvakasimba neSMIC, BOE nemamwe mabhizinesi.

Mamiriro Ekushandisa: Inoshandiswa musemiconductor yakakwira-midziyo inonatsa (semuenzaniso, magetsi-matangi ekuchengetera hydrofluoric acid) nemidziyo yemishonga (semuenzaniso, matangi ekuchengetedza agent) anoda kuchena kwakanyanya uye kushambidzika kwepamusoro. Yakabatsira vatengi kuvandudza chip goho (semuenzaniso, 12-inch wafer goho rakawedzera ne2%) uye kuderedza chigadzirwa kurasikirwa kunokonzerwa nekusachena.
