Incazelo emfushane:

I-Sapphire Substrate ye-Sapphire (PSS) is mask for etching eyomile kwi-subwire substrate, isks aqoshwe ngenqubo ye-lithography ejwayelekile, bese i-sapphire ifakwe yi-epitaxy ye-GAN Le nqubo ifaka izinyathelo eziningana ezinjenge-Photoresist Coating, Ukuvezwa Kwezinyathelo, Ukuthuthukisa Iphethini Yokuvezwa, I-ICP eyomile e-Etching kanye nokuhlanza.

Amathegi Omkhiqizo

Izici eziyinhloko

1. Izici ezihlelekile:
Indawo ye-PSS ine-coner yesigaxa ehlelekile noma esingunxantathu.
Lezi zinhlaka ezinemifanekiso zisiza ukuguqula indlela yokusakazeka yokukhanya futhi yehlise ukubonakaliswa okuphelele kokukhanya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokukhishwa okukhanyayo.

2. Izici ezibonakalayo:
Ama-PSS asebenzisa i-Sapphire esezingeni eliphakeme njengezinto ezisetshenziswayo, ezinezici zobulukhuni obuphezulu, ukuqhutshwa okuphezulu okushisayo, ukuqina okuhle kwamakhemikhali nokubonakala okuhle.
Lezi zici zivumela ama-PS ukumelana nezimo ezinzima njengamazinga okushisa aphezulu kanye nezingcindezi ngenkathi kugcinwa ukusebenza okuhle kakhulu.

3. Ukusebenza kwe-Optical:
Ngokushintsha ukusakazwa okuningi endaweni ebonakalayo phakathi kwe-gan nesafire substrate, ama-PSS enza ama-photons aboniswa ngokuphelele ngaphakathi kwe-gan ungqimba athola ithuba lokuphunyuka ekuphunyukeni kwesafire substrate.
Lesi sici sithuthukisa kakhulu ukusebenza kahle kokukhishwa kwe-LED futhi sithuthukise ubukhulu be-LED.

4. Izici zenqubo:
Inqubo yokukhiqiza yama-PS iyinkimbinkimbi, efaka izinyathelo eziningi ezifana ne-lithography kanye ne-etchiograph, futhi idinga imishini enokunemba okuphezulu nokulawulwa kwenqubo.
Kodwa-ke, ngentuthuko eqhubekayo yezobuchwepheshe kanye nokwehliswa kwezindleko, inqubo yokukhiqiza yama-PSS ilungiselelwe kancane kancane futhi yathuthukiswa.

Inzuzo enkulu

I-1.Improve ukukhishwa kokukhishwa kokukhanya: Ama-PSS athuthukisa kakhulu ukusebenza kahle kokukhishwa kwe-LED ngokushintsha indlela yokusakazeka yokukhanya kanye nokunciphisa ukuboniswa okuphelele.

I-2.prolong Led Life: Ama-PSS anganciphisa ukuhlukaniswa kwabantu kwezinto zokwakha ze-gan, ngaleyo ndlela anciphise ukubuyiselwa kabusha okungahleliwe kanye nokubuyiselwa emuva kokuvuza kwesifunda esisebenzayo, ukunweba impilo ye-LED.

3.Impire LED BELKNESS: Ngenxa yokuthuthuka kokusebenza kahle kokukhishwa kokukhanya kanye nokunwetshwa kwempilo ye-LED, ubukhulu obukhanyiswa ama-luminous kuma-PSS kuthuthukiswa kakhulu.

Izindleko zokukhiqiza 4. Yize inqubo yokukhiqiza yama-PS iyinkimbinkimbi, ingathuthukisa kakhulu ukusebenza kahle okukhanyayo nempilo ye-LED, ngaleyo ndlela kunciphisa izindleko zokukhiqiza ngezinga elithile.

Izindawo eziphambili zesicelo

1. Ukukhanyisa kwe-LED: ama-PSS njengento engezansi ye-substrate yama-chips aholwa, angathuthukisa kakhulu ukusebenza kahle okukhanyayo nempilo ye-LED.
Ensimini yokukhanyisa kwe-LED, ama-PSS asetshenziswa kabanzi emikhiqizweni ehlukahlukene yokukhanyisa, njengamalambu omgwaqo, izibani zetafula, amalambu ezimoto nokunye.

Amadivayisi we-Omiemiemiemictor: Ngaphezu kokukhanyisa kwe-LED, ama-PSS nawo angasetshenziswa ukukhiqiza amanye amadivaysi ama-semiconductor, ama-lasers, njll. Lawa madivayisi anezinhlelo eziningi zezokuxhumana, ezokwelashwa, ezempi kanye nezinye izinkambu.

Ukuhlanganiswa kwe-3.Optoelectronic: Izakhiwo ze-Optical kanye nokuqina kwama-PS
