Iimbonakalo
1. Inqanaba eliphezulu lokukhuselwa kwendalo: i-etching ekhethiweyo inokufezekiswa ngaphandle kokusetyenziswa kweziseko eziphilayo ezifana ne-TMAH;
2. Ixabiso eliphantsi lokuvelisa: Xa kuthelekiswa nokuphathwa kwangaphambili okuqhelekileyo kusetyenziswa i-hydrofluoric acid / i-nitric acid kwimarike, ixabiso lemveliso liyancipha kakhulu;
3. Ukusebenza okuphezulu kwe-etching: Xa kuthelekiswa nenkqubo yebhetri yePerc, ukusebenza kakuhle kokuguqulwa kwanda ngaphezu kwe-1.2%;
| Ubungakanani bewafer | Imbonakalo | Ukuguqulwa kombane | Ubomi |
