ukuqonda inkqubo yokucoca kunye nongcoliseko lwe-semiconductor wafer

Xa isidoda sisiyaiindaba zoshishino, ukuqonda ubuchule bokwenziwa kwe-semiconductor kuyimfuneko. I-semiconductor wafer ziyinxalenye ebalulekileyo kweli shishini, kodwa zihlala zijongene nongcoliseko oluvela kwiintlobo ngeentlobo zokungcola. Ezi zinto zingcolisayo, kuquka i-atom, izinto eziphilayo, i-metallic element ion, kunye ne-oxide, zinokuchaphazela inkqubo yokwenziwa.

Amasuntswanaezifana ne-polymer kunye nokungcola okutyhidiweyo, ukuthembela kumandla aphakathi kweemolekyuli ukufunxa kumphezulu we-wafer, kuchaphazela i-photolithography yesixhobo.ukungcola kwezinto eziphilayonjengeoyile yesikhumba sehomo kunye nefilimu yeoyile yomatshini kwi-wafer, zithintela ukucoca.ii-ion ze-metallic elementNjengentsimbi kunye ne-aluminium zihlala zisuswa ngokwenziwa kwe-ion complex ye-metallic element.IiOxidesiyathintela inkqubo yokwenziwa kwaye idla ngokususwa ngokucwiliswa kwi-hydrofluoric acid enyibilikisiweyo.

iindlela zeekhemikhaliZisetyenziswa rhoqo ukucoca nokuhluza i-wafer ye-semiconductor. Indlela yokucoca iikhemikhali zokufuma efana nokuntywiliselwa kwisisombululo kunye nokukhuhla ngoomatshini iyasebenza. Indlela yokucoca i-supersonic kunye ne-megasonic inikezela ngeendlela ezisebenzayo zokususa ukungcola. Ukucoca iikhemikhali ezomileyo, kubandakanya itekhnoloji ye-plasma kunye ne-gas phase, ikwadlala indima kwiinkqubo zokucoca ii-wafer ze-semiconductor.
