Ha peō ea botona holitaba tsa khoebo, ho utloisisa bokhabane ba boqapi ba semiconductor hoa hlokahala. semiconductor wafer ke karolo ea bohlokoa indastering ena, empa hangata ba tobana le tšilafalo e tsoang ho litšila tse fapaneng. Lintho tsena tse silafatsang, tse kenyelletsang athomo, lintho tse phelang, metallic element ion, le oxide, li ka ama mokhoa oa ho etsa.
Likaroloanajoalo ka polymer le etching ditshila trust on intermolecular force to adsorb on the wafer of the wafer, ama sesebediswa photolithography.litšila tse phelangjoalo ka oli ea letlalo la homo le filimi ea oli ea mochini holim'a sephaphatha, e sitisa ho hloekisa.li-ion tsa tšepejoalo ka tšepe le aluminium hangata li tlosoa ka sebopeho sa metallic element ion complex.Li-oxidee sitisa mokhoa oa ho etsa 'me hangata e tlosoa ka ho inela ka har'a dilute hydrofluoric acid.
mekhoa ea lik'hemik'haleHangata li sebelisoa ho hloekisa le ho jerk semiconductor semiconductor. Mokhoa oa ho hloekisa lik'hemik'hale oa mongobo joalo ka ho qoelisoa ha metsi le mochini o hohloa o atile. supersonic le megasonic ho hloekisa mokhoa o fana ka litsela tse sebetsang tsa ho tlosa litšila. ho hloekisa lik'hemik'hale tse omeletseng, ho kenyelletsa theknoloji ea plasma le khase, hape e phetha karolo ea bohlokoa lits'ebetsong tsa ho hloekisa semiconductor wafer.
