Semicerafaailoa mai lona tulaga maualugaO le Epitaxy'au'aunaga, ua fuafuaina e fa'amalieina tulaga fa'ata'atia o le alamanuia semiconductor i aso nei. Epitaxial silicon layers e taua tele mo le faʻatinoga ma le faʻatuatuaina o masini faʻaeletoroni, ma o matou Si Epitaxy fofo e faʻamautinoa ai o au vaega e ausia galuega sili ona lelei.
Fa'ato'aga Sili-Tula'i Sili Semiceramalamalama o le faavae o masini maualuga-faatinoga o loʻo taoto i le lelei o mea faʻaoga. O tatouO le Epitaxye fa'atonu lelei le fa'agasologa ina ia maua ai fa'a'a'ai kosi ma tulaga fa'apitoa ma le fa'amaoni tioata. O nei laulau e taua tele mo faʻaoga e amata mai i microelectronics i masini eletise maualuga, lea e sili ona taua le tumau ma le faʻamaoni.
Fa'atonuina mo le fa'atinoga o masiniO leO le Epitaxy'au'aunaga o lo'o ofoina mai e Semicera o lo'o fa'atulagaina e fa'aleleia atili ai le eletise o au masini. E ala i le fa'atupuina o laulau silikoni mama-maualalo ma le tele o fa'aletonu, matou te fa'amautinoa o lo'o fa'atinoina au vaega i le tulaga sili, fa'atasi ai ma le fa'aleleia atili o le fe'avea'i ma fa'aitiitia le fa'asao eletise. O lenei fa'ata'ita'iga e taua tele mo le ausiaina o uiga maualuga-saosaoa ma maualuga-lelei e mana'omia e tekinolosi fa'aonaponei.
Fetuuna'i i Talosaga Semicera'sO le Epitaxye talafeagai mo le tele o faʻaoga, e aofia ai le gaosiga o le CMOS transistors, power MOSFETs, ma le bipolar junction transistors. O la matou faiga fetuutuunai e mafai ai ona faʻapipiʻiina e faʻavae i luga o manaʻoga faʻapitoa o lau poloketi, pe e te manaʻomia ni laupepa manifinifi mo faʻaoga maualuga pe sili atu le mafiafia mo masini eletise.
Tulaga Sili MeaO le lelei o le fatu lea o mea uma matou te faia i Semicera. O tatouO le Epitaxyfa'agasologa fa'aogaina meafaigaluega fa'aonaponei fa'aonaponei ma faiga fa'apitoa e fa'amautinoa ai e fa'amalieina ta'itasi fa'a-silikoni tulaga maualuga o le mama ma le fa'atonuga fa'atulagaina. O le gauai atu i auiliiliga e faaitiitia ai le tulai mai o faaletonu e ono aafia ai le faatinoga o masini, ma maua ai vaega sili atu ona faatuatuaina ma umi.
Tautinoga i Faiga Fou Semiceraua tautino e tumau i le pito i luma o tekinolosi semiconductor. O tatouO le Epitaxy'au'aunaga o lo'o atagia ai lenei tautinoga, fa'atasi ai ma fa'auluuluga aupito lata mai i metotia fa'atupu fa'a-epitaxial. Matou te faʻaauau pea ona faʻaleleia a matou faʻagasologa e tuʻuina atu ai lapisi silicon e fetaui ma manaʻoga faʻaleleia o le alamanuia, faʻamautinoa o loʻo tumau pea au oloa i le tauvaga i le maketi.
Fofo Fa'atatau mo Ou Mana'ogaMalamalama o galuega uma e tulaga ese,Semiceraofo fa'apitoaO le Epitaxyfofo e fetaui ma ou manaoga faapitoa. Pe e te manaʻomia ni faʻamatalaga faʻapitoa o le doping, mafiafia o le lapisi, poʻo le faʻamaeʻaina o luga, e galulue vavalalata le matou 'au e tuʻuina atu se oloa e fetaui ma au faʻamatalaga saʻo.
