Njira ya okosijeni

Masitepe otsatirawa nthawi zambiri amaphatikizidwa munjira ya okosijeni:

1. Kudyetsa zopangira: Gwiritsani ntchito mapaipi kuti mupereke zida ku riyakitala kuti musunge bwino zinthu zopangira mkati.
2. Zochita: Kuti mugwiritse ntchito makutidwe ndi okosijeni, onjezani mpweya ku riyakitala ndikuwongolera momwe zimayendera (monga kutentha, kuthamanga, ndi nthawi yochitira).
3. Kulekanitsa katundu: Gwiritsani ntchito choziziritsira mpweya kuziziritsa zinthu zomwe zachitika, kutembenuza kuchokera ku mpweya kukhala wamadzimadzi kapena olimba, kenako gwiritsani ntchito cholekanitsa kuti mulekanitse zinthu zochokera kuzinthu zosiyanasiyana.
4. Kuyeretsedwa: Kuonetsetsa kuti zomwe zimapangidwira zikufika pachiyero chofunikira, yeretsani.
5. Kupaka: Zogulitsazo zikatsukidwa, zimayikidwa motsatira malangizo ndi miyezo musanagulitsidwe kwa makasitomala kapena kutumizidwa ku gawo lotsatira la kukonza.

Muzinthu zina zapadera, monga semiconductor wafer processing, ndondomeko ya okosijeni imaphatikizaponso kupereka zowonjezera zowonjezera (monga madzi, mpweya) ndi mphamvu zotentha pa gawo lapansi la silicon kuti apange filimu ya silicon dioxide (SiO2).Kanema wa oxide uyu amateteza chophatikizikacho poletsa kutayikira kwaposachedwa pakati pa mabwalo, kuteteza kufalikira panthawi ya kuyika kwa ion, ndikuchita ngati filimu yotsutsa-etching yomwe imalepheretsa kuyika molakwika panthawi yolumikizira.
