Semicera's10x10mm M-diyaarad Aluminium Substrate ah oo aan polar ahaynwaxaa si taxadar leh loogu talagalay in lagu buuxiyo shuruudaha saxda ah ee codsiyada horumarsan ee optoelectronic. Substrate-kani waxa uu leeyahay hanuuninta diyaarada M-nonpolar, taas oo muhiim u ah yaraynta saamaynta polarization ee aaladaha ay ka midka yihiin LEDs iyo diodes-ka leysarka, taas oo u horseedaysa waxqabadka iyo hufnaanta.
The10x10mm M-diyaarad Aluminium Substrate ah oo aan polar ahaynwaxaa lagu farsameeyay tayada crystalline gaar ah, hubinta cufnaanta cilladaha ugu yar iyo sharafta qaabdhismeedka sare. Tani waxay ka dhigaysaa doorasho ku habboon koritaanka epitaxial ee filimada tayada sare leh ee III-nitride, kuwaas oo lagama maarmaan u ah horumarinta qalabka soo socda ee optoelectronic.
Injineernimada saxda ah ee Semicera ayaa hubisa mid walba10x10mm M-diyaarad Aluminium Substrate ah oo aan polar ahaynwaxay bixisaa dhumuc joogto ah iyo fidsanaan dusha sare ah, kuwaas oo muhiim u ah dhigista filimada isku midka ah iyo samaynta qalabka. Intaa waxaa dheer, cabbirka is haysta ee substrate-ka ayaa ka dhigaya mid ku habboon cilmi-baarista iyo deegaanka wax-soo-saarka labadaba, taas oo u oggolaanaysa adeegsiga dabacsanaan ee codsiyada kala duwan. Iyada oo kuleylkeeda iyo xasilloonida kiimikada ee heer sare ah, substrate-kani wuxuu bixiyaa aasaas la isku halleyn karo oo horumarinta tignoolajiyada casriga ah ee optoelectronic.
