Chomera cha Sapphire Substrate (PSS) cha mainchesi awiri, mainchesi anayi, mainchesi asanu ndi limodzi (2 inchi) chomwe chimalimidwa ndi GaN chingagwiritsidwe ntchito powunikira LED.
Zinthu zazikulu
1. Makhalidwe a kapangidwe kake:
Pamwamba pa PSS pali koni yokonzedwa bwino kapena mawonekedwe a koni ya triangular omwe mawonekedwe ake, kukula kwake, ndi kufalikira kwake zimatha kulamulidwa mwa kusintha magawo a njira yopangira.
Kapangidwe ka zithunzizi kamathandiza kusintha njira yofalitsira kuwala ndikuchepetsa kuwunikira konse kwa kuwala, motero kumawonjezera mphamvu yotulutsa kuwala.
2. Makhalidwe a zinthu:
PSS imagwiritsa ntchito safiro yapamwamba kwambiri ngati chinthu chopangira zinthu, chomwe chili ndi mawonekedwe a kuuma kwambiri, kutentha kwambiri, kukhazikika kwa mankhwala komanso kuwonekera bwino kwa kuwala.
Makhalidwe amenewa amathandiza PSS kupirira malo ovuta monga kutentha kwambiri ndi kupsinjika pamene ikugwira ntchito bwino kwambiri.
3. Kugwira ntchito kwa kuwala:
Mwa kusintha kufalikira kwa zinthu zambiri pakati pa GaN ndi safiro, PSS imapangitsa kuti ma photon omwe amaonekera bwino mkati mwa GaN layer akhale ndi mwayi wothawa kuchokera ku safiro.
Mbali imeneyi imapangitsa kuti kuwala kwa LED kukhale kothandiza kwambiri komanso kuti kuwala kwa LED kukhale kowala kwambiri.
4. Makhalidwe a njira:
Njira yopangira PSS ndi yovuta kwambiri, yokhala ndi masitepe angapo monga kujambula ndi kusindikiza, ndipo imafuna zida zolondola kwambiri komanso kuwongolera njira.
Komabe, chifukwa cha kupita patsogolo kwa ukadaulo komanso kuchepetsa ndalama, njira yopangira PSS imakonzedwa pang'onopang'ono komanso kusinthidwa.
Ubwino waukulu
1. Kuwongolera bwino ntchito yotulutsa kuwala: PSS imawongolera kwambiri ntchito yotulutsa kuwala kwa LED mwa kusintha njira yofalitsira kuwala ndikuchepetsa kuwunikira konse.
2. Kutalikitsa nthawi ya LED: PSS imatha kuchepetsa kuchuluka kwa zinthu za GaN epitaxial zomwe zimasokonekera, motero kuchepetsa kubwerezabwereza kwa kuwala ndi kubweza kwa magetsi m'dera lomwe likugwira ntchito, zomwe zimapangitsa kuti LED ikhale ndi moyo wautali.
3. Konzani kuwala kwa LED: Chifukwa cha kusintha kwa mphamvu yotulutsa kuwala komanso kukulitsa moyo wa LED, mphamvu ya kuwala kwa LED pa PSS imawonjezeka kwambiri.
4. Chepetsani ndalama zopangira: Ngakhale kuti njira yopangira PSS ndi yovuta, imatha kusintha kwambiri kuwala ndi moyo wa LED, motero kuchepetsa ndalama zopangira mpaka pamlingo winawake ndikukweza mpikisano wa chinthucho.
Madera akuluakulu ogwiritsira ntchito
1. Kuwala kwa LED: PSS ngati chinthu chopangira ma chips a LED, imatha kusintha kwambiri kuwala ndi moyo wa LED.
Pankhani ya magetsi a LED, PSS imagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zowunikira, monga nyali za pamsewu, nyali za patebulo, nyali zamagalimoto ndi zina zotero.
2. Zipangizo za Semiconductor: Kuwonjezera pa kuwala kwa LED, PSS ingagwiritsidwenso ntchito popanga zipangizo zina za semiconductor, monga zowunikira kuwala, ma laser, ndi zina zotero. Zipangizozi zili ndi ntchito zosiyanasiyana pakulankhulana, zachipatala, zankhondo ndi zina.
3. Kuphatikiza kwa Optoelectronic: Kapangidwe ka kuwala ndi kukhazikika kwa PSS zimapangitsa kuti ikhale imodzi mwa zipangizo zabwino kwambiri pakuphatikiza kwa optoelectronic. Mu kuphatikiza kwa optoelectronic, PSS ingagwiritsidwe ntchito kupanga ma waveguides a kuwala, ma switch a kuwala ndi zigawo zina kuti zigwire ntchito yotumiza ndi kukonza zizindikiro za kuwala.

XKH imayang'ana kwambiri pakupanga, kupanga, ndi kugulitsa zinthu zopangidwa ndi safiro (PSS), ndipo yadzipereka kupereka zinthu zapamwamba komanso zogwira ntchito bwino za PSS kwa makasitomala padziko lonse lapansi. XKH ili ndi ukadaulo wapamwamba wopanga zinthu komanso gulu la akatswiri aukadaulo, lomwe lingathe kusintha zinthu za PSS ndi mafotokozedwe osiyanasiyana komanso kapangidwe kake kosiyanasiyana malinga ndi zosowa za makasitomala. Nthawi yomweyo, XKH imaganizira kwambiri za mtundu wa malonda ndi mtundu wa ntchito, ndipo yadzipereka kupatsa makasitomala chithandizo chaukadaulo ndi mayankho osiyanasiyana. Mu gawo la PSS, XKH yasonkhanitsa zokumana nazo zambiri komanso zabwino, ndipo ikuyembekezera kugwira ntchito limodzi ndi ogwirizana nawo padziko lonse lapansi kuti alimbikitse limodzi chitukuko chatsopano cha magetsi a LED, zida za semiconductor ndi mafakitale ena.
