Semicera's SOI Wafer (Silicon On Insulator) ua mamanuina e tuʻuina atu le faʻaesea eletise sili atu ma le faʻaogaina o le vevela. O lenei fausaga fou o le wafer, e faʻaalia ai le silicon layer i luga o le insulating layer, faʻamautinoaina le faʻaleleia atili o le masini ma faʻaitiitia le faʻaogaina o le eletise, ma faʻamaonia ai mo le tele o faʻaoga tekonolosi.
O matou SOI wafers e ofoina atu faʻamanuiaga faʻapitoa mo taʻaloga tuʻufaʻatasia e ala i le faʻaitiitia o le malosi o le parasitic ma faʻaleleia le saoasaoa ma le lelei o masini. E taua tele lenei mea mo mea fa'aonaponei fa'aeletonika, lea e mana'omia ai le maualuga o le fa'atinoga ma le fa'aleleia o le malosi mo fa'atauga ma fa'aoga tau alamanuia.
O lo'o fa'aaogaina e Semicera ni faiga fa'apitoa tau gaosiga e maua mai ai soi wafers ma le lelei ma le fa'amaoni. O nei wafers e tuʻuina atu ai le faʻaogaina o le vevela sili ona lelei, e faʻaoga lelei ai mo le faʻaogaina i totonu o siosiomaga e faʻafefe ai le vevela o se popolega, e pei o le maualuga o masini eletise ma le puleaina o le eletise.
O le fa'aogaina o soi wafers i le semiconductor fabrication e mafai ai ona fa'atupuina mea laiti, vave, ma sili atu ona fa'atuatuaina. O le tautinoga a Semicera i le fa'ainisinia sa'o e fa'amautinoa ai e ausia e a tatou wafers SOI tulaga maualuga e mana'omia mo tekonolosi fa'aonaponei i matā'upu e pei o feso'ota'iga, ta'avale, ma mea fa'akomepiuta fa'atau.
Filifilia o le Semicera's SOI Wafer o lona uiga o le teu fa'afaigaluegaina i se oloa e lagolago ai le fa'agasolo i luma o tekinolosi fa'aeletonika ma microelectronic. O a matou wafers ua mamanuina e tuʻuina atu ai le faʻaleleia atili o le faʻatinoga ma le tumau, e saofagā i le manuia o au galuega faʻatekonolosi maualuga ma faʻamautinoa e te tumau i le pito i luma o mea fou.
