Semiceraua fiafia e ofoina atu lePFA Kaseti, o se filifiliga fa'apitoa mo le fa'aogaina o le wafer i totonu o si'osi'omaga o lo'o fa'asilisili ai le tete'e o vaila'au ma le tumau. Fausia mai le maualuga-mama Perfluoroalkoxy (PFA) mea, o lenei kaseti ua mamanuina e tatalia tulaga sili ona faigata i le semiconductor fabrication, faʻamautinoa le saogalemu ma le faʻamaoni o au wafers.
Tete'e Vailaau Fa'atusaO lePFA Kasetiua fa'ainisinia e maua ai le tete'e sili atu i le tele o vaila'au, ma avea ai ma filifiliga lelei mo faiga e aofia ai vaila'au fa'amalosi, solvents, ma isi vaila'au malosi. O le malosi malosi lea o vaila'au e fa'amautinoa ai o lo'o tumau pea le kaseti ma galue e o'o lava i si'osi'omaga sili ona pala, ma fa'ateleina ai lona ola ma fa'aitiitia ai le mana'omia mo le sui soo.
Fausia-Mama maualugaSemicera'sPFA Kasetie gaosia mai mea PFA ultra-mama, lea e taua tele i le puipuia o le faʻaleagaina i le taimi o le gaosiga o wafer. O lenei faufale maualuga-mama e fa'aitiitia ai le a'afiaga o le fa'atupuina o fasimea ma le fa'amama kemisi, fa'amautinoa o lo'o puipuia au fa'ama'i mai mea leaga e ono fa'aleagaina ai lo latou lelei.
Faʻaleleia le Tumau ma FaʻatinogaFuafuaina mo le tumau, lePFA Kasetifa'atumauina lona fa'atonuga fa'atulagaina i lalo o le vevela tele ma tulaga fa'agaoioiga faigata. Pe faʻaalia i le maualuga o le vevela pe faʻafeiloaʻi i le faʻaaogaina faifaipea, o lenei kaseti e tumau pea lona foliga ma le faʻatinoga, ofoina atu le faʻatuatuaina umi i le manaʻomia o siosiomaga gaosiga.
Fa'ainisinia Sa'o mo le Taulima SaogalemuO leSemicera PFA Kasetifa'aalia fa'ainisinia sa'o e fa'amautinoa ai le saogalemu ma le mautu o le tagofiaina o wafer. Ua mamanuina ma le faaeteete avanoa ta'itasi e taofi mau ai ma fa'amau lelei i totonu, puipuia ai so'o se gaioiga po'o se suiga e ono fa'aleagaina. O lenei inisinia sa'o e lagolagoina le tu'u sa'o ma le sa'o, e saofagā i le fa'atinoina o le fa'agasologa atoa.
Talosaga Fetuuna'i i Fa'asologa Fa'asologaFa'afetai i ana meafaitino sili atu, lePFA Kasetie lava le fa'aogaina e fa'aoga i vaega eseese o le gaosiga semiconductor. E sili ona fetaui lelei mo le susū susū, vaila'au va'a (CVD), ma isi fa'agasologa e a'afia ai si'osi'omaga o vaila'au malosi. O lona fetuutuuna'i ua avea ai ma meafaigaluega taua i le faatumauina o le amiosa'o o le faagasologa ma le lelei o le wafer.
Tautinoga i Tulaga Lelei ma Fa'afouinaI Semicera, matou te tuuto atu i le tuʻuina atu o oloa e fetaui ma tulaga maualuga o alamanuia. O lePFA Kasetifa'ata'ita'iina lenei tautinoga, ofoina atu se tali fa'atuatuaina e tu'ufa'atasia lelei i au fa'agasologa o gaosiga. O kaseti ta'itasi o lo'o fa'atinoina le fa'atonuga lelei ina ia mautinoa e fetaui ma a tatou fa'ata'ita'iga malosi, fa'aolaina le tulaga lelei e te fa'amoemoeina mai Semicera.
