Ma LED anovhenekera nyika yedu, uye pamwoyo weyese yepamusoro-inoshanda LED inoraraepitaxial wafer-chikamu chakakosha chinotsanangura kupenya kwayo, ruvara, uye kugona. Nekuziva sainzi yekukura kwe epitaxial, vagadziri vari kuvhura mikana mitsva yekuchengetedza simba uye inodhura-inoshanda magetsi mhinduro.
1. Nzira Dzakangwara dzeKukura dzeKubudirira Kukuru
Mazuva ano mwero wematanho maviri ekukura maitiro, kunyange achibudirira, anoganhura scalability. Mazhinji mareactor ekutengesa anokura chete mawafer matanhatu pabatch. Iyo indasitiri iri kutamira kune:
- High-capacity reactorsiyo inobata mawafer akawanda, kucheka mitengo uye kuwedzera throughput.
- Yakanyanya otomatiki single-wafer michinakuitira kusimba kwepamusoro uye kudzokorora.
2. HVPE: Nzira Inokurumidza kuenda Kumhando Dzepamusoro-soro
Hydride Vapor Phase Epitaxy (HVPE) inokurumidza kugadzira akakora eGaN akaturikidzana ane mashoma akaremara, akakwana sema substrates edzimwe nzira dzekukura. Aya mafirimu eGaN akasununguka anogona kukwikwidzana neGaN chips. Kubata? Hukobvu hwakaoma kudzora, uye makemikari anogona kukanganisa michina nekufamba kwenguva.
3. Kukura Kweparutivi: Makristasi Akanyorovera, Chiedza Zvirinani
Nekunyatso gadzira wafer nemasks nemahwindo, vagadziri vanotungamira GaN kuti ikure kwete kumusoro, asi padivi zvakare. Iyi "lateral epitaxy" inozadza mumipata ine hurema hushoma, ichigadzira imwe isina kukanganisa crystal chimiro chepamusoro-inoshanda ma LED.
4. Pendeo-Epitaxy: Kurega Makristasi Ayangarara
Hechino chimwe chinhu chinonakidza: mainjiniya anokura GaN pamakoramu marefu uye obva aisiya "bhiriji" panzvimbo isina chinhu. Kukura kunoyangarara uku kunobvisa kunetsa kwakawanda kunokonzerwa nezvinhu zvisingaenderane, zvichipa matinji ekristaro akasimba uye akachena.
5. Kupenya UV Spectrum
Zvishandiso zvitsva zviri kusunda mwenje we LED kudzika mukati meiyo UV renji. Nei izvi zvine basa? Chiedza cheUV chinogona kumisa phosphors yepamberi nehunyanzvi hwepamusoro kupfuura sarudzo dzechinyakare, kuvhura musuwo kune inotevera-gen chena ma LED anopenya uye anowedzera simba-rinoshanda.
6. Multi-Quantum Well Chips: Ruvara kubva Mukati
Panzvimbo yekubatanidza ma LED akasiyana kuti aite mwenje chena, wadii kukura mune imwe chete? Multi-quantum zvakanaka (MQW) machipisi anoita izvo chete nekumisikidza maseru anoburitsa akasiyana wavelengths, kusanganisa mwenje zvakananga mukati meiyo chip. Inoshanda, inobata, uye inoyevedza-asi yakaoma kugadzira.
7. Kudzokorora Chiedza nePhotonics
Sumitomo neBoston University vakaratidza kuti kurongedza zvinhu zvakaita seZnSe neAlInGaP pablue LEDs zvinogona "kudzokorodza" mafotoni muzere chena spectrum. Iyi yakangwara yekuisa dhizaini inoratidza inonakidza fusion yezvishandiso sainzi uye mafotonics kubasa mune yazvino LED dhizaini.
Maitiro e LED Epitaxial Wafers Anoitwa
Kubva pane substrate kuenda kune chip, heino rwendo rwakarerutswa:
- Growth Phase:Substrate → Dhizaini → Buffer → N-GaN → MQW → P-GaN → Anneal → Kuongorora
- Fabrication Phase:Masking → Lithography → Etching → N/P Electrodes → Dicing → Kuronga
Iyi yekunyatsoita maitiro inovimbisa yega yega LED chip inounza kuita kwaunogona kutarisira-kungave kuvheneka skrini yako kana guta rako.
