LED imurikira isi yacu, kandi kumutima wa buri kintu kinini LED ikoraepitaxial wafer—Ikintu gikomeye gisobanura ubwiza bwacyo, ibara, nuburyo bwiza. Mugukoresha ubumenyi bwikura rya epitaxial, abayikora bafungura uburyo bushya bwo kuzigama ingufu no gukemura neza.
1. Ubuhanga bwo Gukura Ubwenge bwo Gukora neza
Uyu munsi usanzwe intambwe ebyiri zo gukura, nubwo zifite akamaro, zigabanya ubunini. Ibicuruzwa byinshi byubucuruzi bikura wafer esheshatu kuri buri cyiciro. Inganda ziragenda zigana:
- Imashini zifite ingufu nyinshiikora wafer nyinshi, kugabanya ibiciro no kuzamura ibicuruzwa.
- Imashini zikoresha cyane imashini imwe-waferkugirango bihamye kandi bisubirwamo.
2. HVPE: Inzira Yihuse Kuri Substrates Yubuziranenge
Hydride Vapor Phase Epitaxy (HVPE) itanga byihuse ibyiciro bya GaN bifite inenge nkeya, byuzuye nkibisobanuro byubundi buryo bwo gukura. Izi firime za GaN zidegembya zishobora no guhangana na chip nyinshi za GaN. Ifatwa? Umubyimba uragoye kugenzura, kandi imiti irashobora kwangiza ibikoresho mugihe.
3. Gukura kuruhande: Crystal yoroshye, urumuri rwiza
Mugushushanya witonze wafer ukoresheje masike na Windows, abayikora bayobora GaN gukura atari hejuru gusa, ariko no kuruhande. Iyi "epitaxy yanyuma" yuzuza icyuho gifite inenge nke, ikora imiterere ya kirisiti itagira inenge ya LED ikora neza.
4. Pendeo-Epitaxy: Kureka Crystal ireremba
Hano hari ikintu gishimishije: abajenjeri bakura GaN kumurongo muremure hanyuma bakareka "ikiraro" hejuru yubusa. Iri terambere rireremba rikuraho byinshi mubibazo biterwa nibikoresho bidahuye, bigatuma habaho kristu ya kirisiti ikomeye kandi yera.
5. Kumurika UV Ikirangantego
Ibikoresho bishya bisunika urumuri rwa LED cyane murwego rwa UV. Kuki iki kibazo? Itara rya UV rirashobora gukora fosifore yateye imbere hamwe nubushobozi buhanitse kuruta amahitamo gakondo, gukingura urugi rwa LED-yera yera ikurikira kandi ikanakoresha ingufu.
6. Multi-Quantum Neza Chips: Ibara riva imbere
Aho guhuza LED zitandukanye kugirango ukore urumuri rwera, kuki utakura byose murimwe? Multi-quantum neza (MQW) chip ibikora gusa mugushiramo ibice bisohora uburebure butandukanye, bivanga urumuri muri chip. Nibyiza, byoroshye, kandi byiza-nubwo bigoye kubyara.
7. Gusubiramo urumuri hamwe na Photonika
Kaminuza ya Sumitomo na Boston yerekanye ko gutondekanya ibikoresho nka ZnSe na AlInGaP kuri LED yubururu bishobora "gusubiramo" fotone muburyo bwuzuye bwera. Ubu buhanga bwo gutondekanya ubwenge bugaragaza guhuza ibintu bishimishije siyanse na fotonike kukazi muburyo bwa LED bugezweho.
Uburyo LED Epitaxial Wafers Yakozwe
Kuva kuri substrate kugeza chip, dore urugendo rworoshye:
- Icyiciro cyo gukura:Substrate → Igishushanyo → Buffer → N-GaN → MQW → P-GaN → Anneal → Kugenzura
- Icyiciro cyo guhimba:Masking → Lithography → Gutera → N / P Electrode → Dices → Gutondeka
Ubu buryo bwitondewe butuma buri LED chip itanga imikorere ushobora kwiringira - haba kumurika ecran yawe cyangwa umujyi wawe.
