Ena ke mokhoa oa ho tlosa Al2O3 ka lik'hemik'hale ho tloha holimo. Nakong ea etching ho Al2O3, tharollo e hanyetsanoa ke aluminium oxide thepa e qhibiliha. Semixlab ena al2o3 metsi etching karabelo e ka fapana ho ea ka mocheso, acidity / basicity (pH) le matla a tharollo.
Mohlala, mocheso o phahameng o ka kenya letsoho ts'ebetsong ea etching e etsahalang kapele, kaha ts'ebetso ea lik'hemik'hale e tla ba matla haholoanyane. Ho feta moo, ho boloka pH e nepahetseng ho ka thibela liketso tse mpe le ho netefatsa hore re beha feela moo re batlang.
Ka Semixlab Al2O3 etching e metsi , hangata re khahloa ke: ho koala ka potlako, ka sekhechana se senyenyane ka hohle kamoo ho ka khonehang. Sekhahla se phahameng se molemo hobane seo se bolela hore re tlosa thepa ka katleho, 'me khetho e ntle hobane e tla re thusa ho boloka karolo e setseng e sireletsehile.
Kahoo o tlameha ho laola liparamente tsa etching, ho kenyelletsa mocheso, boemo ba pH, le khatello ea tharollo, kahoo o fumana sekhahla se phahameng sa etch le khetho e phahameng. Litharollo le mekhoa e khethehileng ea etching le tsona li ka thusa ts'ebetso ho ntlafala le ho potlaka.
Semixlab sephetho le sebopeho se bohlokoa ho al2o3 metsi etching hobane e ka susumetsa sebopeho sa tshebetso sa sehlahiswa sa ho qetela. Re ka ntlafatsa boleng ba bokaholimo ba thepa le sebopeho, ho ipapisitse le taolo ea rona ea lintlha le liparamente tsa ts'ebetso.
Ho sa tsotellehe melemo ea Semixlab Al2O3 ho ruruha ha plasma , e boetse e tobane le liqholotso ntshetsopeleng. Litaba tse ling tse akaretsang li kenyelletsa mokhoa oa ho boloka bokaholimo le libakeng tse kholo, ho laola ponahalo ea libopeho tse pepesitsoeng ke etching, le ho fokotsa ho se phethahale ha thepa.
Ho rarolla mathata ana, bo-ramahlale le baenjiniere ba Semixlab ba ntse ba tsoela pele ho theha mekhoa le mahlale a macha a Al2O3 a ho kolobisa metsi. Ka ho rarolla mathata ana, Semixlab semiconductor etching e ikemiselitse ho eketsa katleho, ho ikatisa le boleng ba etching, ka merero ea khoebo e tsepamisitseng maikutlo ho litholoana tse ntle bakeng sa bareki ba rona.
