I-Semicera's10x10mm Nonpolar M-plane Aluminium Substrateiklanywe ngokucophelela ukuze ihlangabezane nezidingo eziqondile zezinhlelo zokusebenza ezithuthukisiwe ze-optoelectronic. Le substrate ifaka umumo wendiza ye-M engapholi, ebalulekile ekwehliseni imiphumela ye-polarization kumadivayisi afana nama-LED nama-laser diode, okuholela ekusebenzeni okuthuthukisiwe nokusebenza kahle.
I10x10mm Nonpolar M-plane Aluminium Substrateyakhiwe ngekhwalithi ecwebezelayo eyingqayizivele, iqinisekisa ukuminyana okuncane kanye nobuqotho obuphakeme besakhiwo. Lokhu kwenza kube ukukhetha okuhle ekukhuleni kwe-epitaxial kwamafilimu ekhwalithi ephezulu ye-III-nitride, abalulekile ekuthuthukisweni kwamadivayisi esizukulwane esilandelayo se-optoelectronic.
Ubunjiniyela bokunemba be-Semicera buqinisekisa ukuthi ngayinye10x10mm Nonpolar M-plane Aluminium Substrateinikeza ukushuba okungaguquguquki kanye nokucaba kwendawo, okubalulekile ekubekweni kwefilimu okufanayo kanye nokwakhiwa kwedivayisi. Ukwengeza, ubukhulu be-substrate obuhlangene buyenza ifaneleke kokubili indawo yocwaningo neyokukhiqiza, okuvumela ukusetshenziswa okuguquguqukayo ezinhlelweni ezihlukahlukene. Ngokuzinza kwayo okuhle kakhulu kwe-thermal namakhemikhali, le substrate ihlinzeka ngesisekelo esithembekile sokuthuthukiswa kobuchwepheshe be-optoelectronic obusezingeni eliphezulu.
