Semicera's10x10mm Nonpolar M-vaalele Alumea Substrateua mamanuina ma'oti e fa'amalieina mana'oga sa'o o talosaga optoelectronic maualuluga. O lenei substrate o loʻo faʻaalia ai le faʻaogaina o le M-vaalele e le polar, e taua tele mo le faʻaitiitia o aʻafiaga o le polarization i masini e pei o LED ma laser diodes, e taʻitaʻia ai le faʻaleleia o le faʻatinoga ma le lelei.
O le10x10mm Nonpolar M-vaalele Alumea Substrateo lo'o faia i se tulaga fa'apitoa fa'a tioata, fa'amautinoaina le la'ititi o fa'aletonu ma le maualuga o le fa'atonuga. E avea lea ma filifiliga lelei mo le tuputupu aʻe o le epitaxial o ata maualuga III-nitride, lea e taua mo le atinaʻeina o masini optoelectronic e sosoo ai.
Semicera's sa'o fa'ainisinia e fa'amautinoaina e ta'itasi10x10mm Nonpolar M-vaalele Alumea Substratee ofoina atu le mafiafia faifai pea ma le mafolafola o luga, lea e taua tele mo le teuina o ata tifaga ma le gaosiga o masini. E le gata i lea, o le lapopoa o le substrate e fetaui lelei mo suʻesuʻega ma siosiomaga gaosiga, faʻatagaina mo le faʻaogaina fetuutuunai i le tele o talosaga. Faʻatasi ai ma lona faʻamautu lelei o le vevela ma le vailaʻau, o lenei mea faʻapipiʻi e maua ai se faʻavae faʻalagolago mo le atinaʻeina o tekonolosi optoelectronic.
