Ubuchwepheshe, i-GaN MOCVD, kungenzeka bungasuki kalula olimini, kodwa bubaluleke kakhulu ekwenzeni izinto ezisetshenziswa ezintweni ezihlukahlukene njengomakhalekhukhwini, amakhompyutha nezibani ze-LED. I-GaN MOCVD imele i-Gallium Nitride Metal-Organic Chemical Vapor Deposition. Kuyindlela yokukhulisa izendlalelo ezincanyana ngokwedlulele ze-gallium nitride kumpahla yesifanekiso ehlukene — lokho esikubiza ngokuthi i-substrate.
Kunenombolo yezinzuzo ezihlotshaniswa nokwakhiwa kwe-semiconductor esekwe ku-GaN MOCVD. Okokuqala, i-gallium nitride iyimpahla eqinile, eqinile, ngakho-ke amadivaysi enziwe ngayo kufanele ahlale futhi enze kangcono. Okwesibili, nge-Semixlab gan mocvd singakwazi ukulungisa ngokunembe kakhulu ukushuba kwezingqimba ze-gallium nitride. Lokho kubalulekile ekwenzeni ama-semiconductors ekhwalithi ephezulu. Okokugcina, inqubo ye-MOCVD ye-GaN iyahambisana nezinye izinto ezihlanganisiwe ze-semiconductor ezingasetshenziselwa izinhloso ezahlukene.
Ukunaka okuningi futhi kuqondiswe enqubweni yokukhula ngokucophelela ye-GaN MOCVD, ehlanganisa izinyathelo eziningi. Ukuze siqale, sisebenzisa okuthile kusinkwa esilucwecwana bese sikubeka kuleli gumbi. Sibe sesifudumeza ikamelo ekushiseni okuphezulu kakhulu bese siliqhumisa ngamagesi ahlanganisa i-gallium ne-nitrogen. Ebusweni be-substrate ephendula amagesi anjengalawa achazwe ngenhla, ifilimu elincanyana le-gallium nitride liyakhula. Siphinda le nqubo ngokuphindaphindiwe ukuze senze ungqimba lube lukhulu ngendlela esithanda ngayo. Ekugcineni, sipholisa i-substrate kuze kufike izinga lokushisa legumbi, futhi siyikhipha ekamelweni ngezinto ezisezingeni eliphezulu ze-semiconductor.
I-GaN MOCVD ingashintsha ikusasa lemboni ye-semiconductor futhi isisize senze ukusebenza okuphezulu namadivayisi asebenza kahle kakhulu. Isibonelo, i-GaN MOCVD ingase yenze ama-transistors anamandla ezimotweni zikagesi, izibani ze-LED ezisebenza kahle kakhulu namaseli elanga acwengisiswe kakhulu. Ukuthuthuka nokuthuthukela ku-Semixlab mcvd gan ihumushela kumathuba amasha angapheli wamadivayisi akusasa.
Ubuchwepheshe be-GaN MOCVD buyasithembisa futhi bunezinkinga zabo okufanele sizinqobe ngokushesha ukuze sibusebenzise ucwaningo oluxolelwe kahle kakhulu. Inkinga yezindleko kumishini nezinto zokwakha ze-Semixlab i-mocvd reactor okungenani ingenye yezinkinga. Okunye kungaba yinto eyinkimbinkimbi edinga ukuphathwa ngobuhlakani nangobuhlakani. Ngokutshala imali ocwaningweni nasekuthuthukisweni ngokubambisana kwemikhiqizo nabaholi bemboni, singakwazi ukuxazulula lezi zingqinamba futhi siqhubeke nokuphusha umngcele walokho okufinyelelwa ubuchwepheshe be-GaN MOCVD.
