Santimetero 2 na santimetero 4 na santimetero 6 Safiro ifite ishusho (PSS) ihingwaho ibikoresho bya GaN ishobora gukoreshwa mu gucana LED Ishusho yagaragaye

Ibisobanuro bigufi:

Substrate ya safiro ifite ibishushanyo (PSS) ni mask yo gushushanya yumye kuri substrate ya safiro, mask ishushanyijeho ishusho hakoreshejwe uburyo busanzwe bwo gushushanya, hanyuma safiro igashushanywa hakoreshejwe ikoranabuhanga rya ICP, hanyuma mask ikavanwaho, hanyuma ibikoresho bya GaN bigahingwaho, bityo epitaxy y'ibikoresho bya GaN ihinduka epitaxy itambitse. Iyi nzira ikubiyemo intambwe nyinshi nko gusiga photoresist, gushyiramo intambwe, guteza imbere imiterere yo gushushanya, gushushanya yumye kwa ICP no gusukura.

Ibiranga

Ibiranga by'ingenzi

1. Ibiranga imiterere:
Ubuso bwa PSS bufite imiterere y’urukiramende cyangwa imiterere y’urukiramende ifite ishusho, ingano n’uburyo ikwirakwira bishobora kugenzurwa hakoreshejwe uburyo bwo gushushanya.
Iyi miterere y'amashusho ifasha guhindura inzira yo gukwirakwiza urumuri no kugabanya urumuri rwose, bityo bikanoza imikorere yo gukuramo urumuri.

2. Ibiranga ibikoresho:
PSS ikoresha safiro nziza cyane nk'ibikoresho bya substrate, ifite imiterere yo gukomera cyane, imikorere y'ubushyuhe bwinshi, kudahungabana neza mu binyabutabire no kubona urumuri.
Izi miterere zituma PSS ishobora kwihanganira ibidukikije bikomeye nk'ubushyuhe bwinshi n'umuvuduko mu gihe ikomeza gukora neza cyane.

3. Imikorere y'urumuri:
Mu guhindura uburyo bwo gukwirakwiza ibintu byinshi ku murongo uri hagati ya GaN na safiro, PSS ituma fotoni zigaragara neza mu gice cya GaN zigira amahirwe yo kuva muri safiro.
Iyi miterere irushaho kunoza cyane uburyo LED ikuramo urumuri kandi ikongera ubukana bw'urumuri rwa LED.

4. Ibiranga inzira:
Uburyo bwo gukora PSS buragoye cyane, burimo intambwe nyinshi nko gushushanya no gushushanya, kandi bisaba ibikoresho bigezweho no kugenzura uburyo ibintu bikorwamo.
Ariko, hamwe n’iterambere rihoraho ry’ikoranabuhanga no kugabanuka kw’ibiciro, inzira yo gukora PSS igenda irushaho kunozwa no kunozwa buhoro buhoro.

Inyungu y'ibanze

1. Kunoza imikorere myiza yo gukura urumuri: PSS irushaho kunoza imikorere myiza yo gukura urumuri rwa LED binyuze mu guhindura inzira yo gukwirakwiza urumuri no kugabanya urumuri rwose.

2. Kuramba igihe cy'ubuzima bwa LED: PSS ishobora kugabanya ubucucike bw'ibikoresho bya GaN epitaxial, bityo ikagabanya gusubiranamo kw'amashanyarazi kutari imirasire no kugaruka k'umuriro mu gace gakora, bigatuma igihe cy'ubuzima cya LED kirushaho kuba kirekire.

3. Kongera urumuri rwa LED: Bitewe no kunoza imikorere y'urumuri no kongera igihe LED imara, imbaraga z'urumuri rwa LED kuri PSS zirushaho kwiyongera cyane.

4. Kugabanya ikiguzi cyo gukora: Nubwo inzira yo gukora PSS igoye cyane, ishobora kunoza cyane imikorere myiza n'ubuzima bwa LED, bityo bikagabanya ikiguzi cyo gukora ku rugero runaka no kunoza ubushobozi bw'ipiganwa ry'umusaruro.

Ahantu hakuru hakoreshwa

1. Amatara ya LED: PSS nk'igikoresho cy'ibanze cya LED chips, ishobora kongera cyane imikorere myiza n'ubuzima bwa LED.
Mu bijyanye n'amatara ya LED, PSS ikoreshwa cyane mu bikoresho bitandukanye by'amatara, nk'amatara yo ku muhanda, amatara yo ku meza, amatara y'imodoka n'ibindi.

2. Ibikoresho bya semiconductor: Uretse amatara ya LED, PSS ishobora no gukoreshwa mu gukora ibindi bikoresho bya semiconductor, nka za detectors z'urumuri, lazers, nibindi. Ibi bikoresho bifite uburyo bwinshi bwo kubikoresha mu itumanaho, mu buvuzi, mu gisirikare no mu bindi bice.

3. Guhuza optoelectronic: Imiterere y'urumuri n'ubudahangarwa bwa PSS bituma iba imwe mu bikoresho byiza mu bijyanye no guhuza optoelectronic. Mu guhuza optoelectronic, PSS ishobora gukoreshwa mu gukora optical waveguides, optical switches n'ibindi bice kugira ngo ihererekanye kandi itunganywe by'ibimenyetso by'urumuri.

XKH yibanda ku iterambere, umusaruro n'igurishwa rya patterned safiro substrate (PSS), kandi yiyemeje gutanga ibicuruzwa bya PSS byiza kandi bitanga umusaruro mwiza ku bakiriya hirya no hino ku isi. XKH ifite ikoranabuhanga rigezweho mu nganda n'itsinda ry'abahanga mu bya tekiniki, rishobora guhindura ibicuruzwa bya PSS bifite imiterere itandukanye n'imiterere itandukanye bitewe n'ibyo abakiriya bakeneye. Muri icyo gihe, XKH yita ku bwiza bw'ibicuruzwa n'ubwiza bwa serivisi, kandi yiyemeje guha abakiriya inkunga yuzuye ya tekiniki n'ibisubizo. Mu rwego rwa PSS, XKH yakusanyije ubunararibonye n'ibyiza byinshi, kandi yiteze gukorana n'abafatanyabikorwa mpuzamahanga kugira ngo bafatanye guteza imbere iterambere rishya ry'amatara ya LED, ibikoresho bya semiconductor n'izindi nganda.
