kumvetsetsa kuipitsidwa kwa semiconductor wafer ndi njira yoyeretsera

Pamene umuna kutinkhani zamabizinesi, kumvetsetsa kufalikira kwa kupanga semiconductor ndikofunikira. Semiconductor wafer ndi gawo lofunikira kwambiri pamsika uno, koma nthawi zambiri amakumana ndi kuipitsidwa ndi zonyansa zosiyanasiyana. Zoyipa izi, monga atomu, organic matter, metallic element ion, ndi okusayidi, zitha kukhudza njira yopangira.

Tinthu ting'onoting'onomonga polima ndi etching chidetso chidaliro pa intermolecular mphamvu kuti adsorb pamwamba pa mphika, zimakhudza chipangizo photolithography.organic zonyansamonga homo skin oil and machine oil form film pa wafer, amalepheretsa kuyeretsa.zitsulo zinthu ionsmonga chitsulo ndi aluminiyamu nthawi zambiri amachotsedwa mwa kupanga zitsulo zitsulo ion complex.Ma okosijeniAmalepheretsa njira yopangira zinthu ndipo nthawi zambiri amachotsedwa ponyowa mu dilute hydrofluoric acid.

mankhwala njiraNthawi zambiri amagwiritsidwa ntchito kuyeretsa ndi kugwedeza semiconductor wafer. Njira yoyeretsera mankhwala amadzimadzi monga kugwetsa pansi pamadzi ndi makina otsuka amakanika ndizovuta. supersonic ndi megasonic kuyeretsa njira imapereka njira zabwino zochotsera zonyansa. kuyeretsa mankhwala owuma, kuphatikiza ukadaulo wa plasma ndi gasi, imagwiranso ntchito pakuyeretsa kwa semiconductor wafer.
