1. Incamake yuburyo bugezweho muri tekinoroji ya silicon ishingiye kuri LED

Ubwiyongere bwibikoresho bya GaN kuri sisitemu ya silicon bihura nibibazo bibiri byingenzi bya tekiniki. Ubwa mbere, kudahuza lattike igera kuri 17% hagati ya silicon substrate na GaN bivamo ubucucike bwinshi bwo gutandukana imbere mubikoresho bya GaN, bigira ingaruka kumikorere ya luminescence; Icya kabiri, hariho ubushyuhe budahuye bugera kuri 54% hagati ya silicon substrate na GaN, bigatuma firime ya GaN ikunda gucika nyuma yo kwiyongera kwubushyuhe bwinshi no kugabanuka kubushyuhe bwicyumba, bikagira ingaruka kumusaruro. Kubwibyo, gukura kwa buffer hagati ya silicon substrate na GaN yoroheje ya firime ni ngombwa cyane. Igice cya buffer kigira uruhare mukugabanya ubucucike bwa dislocation imbere muri GaN no kugabanya gucika kwa GaN. Ahanini, urwego rwa tekiniki rwurwego rwa buffer rugena imikorere ya kwant imbere yumusaruro numusaruro wa LED, aribyo byibandwaho ningorabahizi zishingiye kuri siliconLED. Kugeza ubu, hamwe n’ishoramari rikomeye mu bushakashatsi n’iterambere ryaturutse mu nganda no muri za kaminuza, iki kibazo cy’ikoranabuhanga cyaratsinzwe.

Silicon substrate ikurura cyane urumuri rugaragara, firime ya GaN rero igomba kwimurirwa mubindi substrate. Mbere yo kwimurwa, urumuri rwerekana cyane rwinjizwa hagati ya firime ya GaN nizindi substrate kugirango birinde urumuri rwatanzwe na GaN kutinjira na substrate. Imiterere ya LED nyuma yo kwimura substrate izwi muruganda nka chip ya Thin Film. Chip ya firime ntoya ifite ibyiza kurenza imiterere yimiterere yimiterere muburyo bwo gukwirakwiza ubu, ubushyuhe bwumuriro, hamwe nuburinganire.

2. Incamake yuburyo bugezweho bwo gusaba hamwe nisoko rusange rya silicon substrate LEDs

LED ishingiye kuri silicon ifite imiterere ihagaritse, ikwirakwizwa ryubu, hamwe no gukwirakwizwa byihuse, bigatuma bikenerwa nimbaraga nyinshi zikoreshwa. Bitewe numucyo wuruhande rumwe rusohoka, icyerekezo cyiza, hamwe nubuziranenge bwurumuri, birakwiriye cyane cyane kumurika rya terefone nko kumurika ibinyabiziga, amatara yo gushakisha, amatara acukura amabuye y'agaciro, amatara ya terefone igendanwa, hamwe n’umuriro wo mu rwego rwo hejuru ufite urumuri rwinshi rusabwa .

Tekinoroji hamwe nibikorwa bya Jingneng Optoelectronics silicon substrate LED imaze gukura. Hashingiwe ku gukomeza kugumana inyungu ziyobora mubijyanye na silicon substrate yubururu bwa LED chip, ibicuruzwa byacu bikomeje kwaguka kumurima bisaba urumuri rwerekezo hamwe nibisohoka byujuje ubuziranenge, nkurumuri rwera LED chip hamwe nibikorwa byiyongereye kandi byongerewe agaciro Amatara ya terefone igendanwa ya LED, amatara yimodoka ya LED, amatara yo kumuhanda LED, amatara yinyuma ya LED, nibindi, buhoro buhoro ashyiraho umwanya mwiza wa silicon substrate LED chip mu nganda zigabanijwe.

3. Iterambere ryiterambere rya silicon substrate LED

Kunoza imikorere yumucyo, kugabanya ibiciro cyangwa gukoresha-ikiguzi ni insanganyamatsiko ihoraho muriInganda LED. Silicon substrate yoroheje ya firime igomba kuba ipakiwe mbere yuko ikoreshwa, nigiciro cyo gupakira konti kubice byinshi byigiciro cya LED. Kureka gupakira gakondo hanyuma ugapakira neza ibice kuri wafer. Muyandi magambo, ipaki yipakurura (CSP) kuri wafer irashobora gusimbuka impera hanyuma igahita yinjiza amaherezo ya porogaramu uhereye kumpera ya chip, bikagabanya igiciro cyo gusaba LED. CSP nimwe mubyifuzo bya GaN ishingiye kuri LED kuri silicon. Amasosiyete mpuzamahanga nka Toshiba na Samsung yatangaje ko akoresha LEDs ishingiye kuri silicon kuri CSP, kandi bikaba byemezwa ko ibicuruzwa bifitanye isano vuba bizaboneka ku isoko.

Mu myaka yashize, ahandi hantu hashyushye mu nganda za LED ni Micro LED, izwi kandi ku rwego rwa micrometero LED. Ubunini bwa Micro LEDs buva kuri micrometero nkeya kugeza kuri micrometero mirongo, hafi kurwego rumwe nubunini bwa firime ya GaN yoroheje ikura na epitaxy. Ku gipimo cya micrometero, ibikoresho bya GaN birashobora gukorwa muburyo butaziguye GaNLED ihagaritse bidakenewe inkunga. Nukuvuga ko, mugikorwa cyo gutegura Micro LEDs, substrate yo gukura GaN igomba kuvaho. Inyungu karemano ya LED ishingiye kuri silikoni ni uko insimburangingo ya silicon ishobora gukurwaho hifashishijwe imiti yatose yonyine, nta ngaruka bigira ku bikoresho bya GaN mugihe cyo kuyikuraho, bigatuma umusaruro wizewe. Urebye, tekinoroji ya silicon substrate LED igomba kuba ifite umwanya murwego rwa Micro LEDs.
