Mumunda wepamusoro-tsanangudzo RGB yekuratidzira machipisi, kumberi-kukwira, flip-chip uye zvakamira zvimisikidzo "mbiru nhatu", pakati peiyo yakajairwa sapphire kumberi-kumberi uye flip-chip zvimiro zvakajairika, uye zvakamira zvimiro zvinowanzoreva kutetepa. -firimu machipisi e LED akabviswa kubva kune substrate.Iyo substrate nyowani inogona kugadziriswa kana iyo substrate inogona kusasungirirwa kugadzira yakatwasuka chip.
Zvinoenderana nekuratidzira masikirini ane mapiji akasiyana, zvakanakira uye zvakaipira zvemberi-gomo, flip-chip uye vertical zvimiro zvakasiyana, asi zvisinei nekuenzanisa iyo yekumberi-gomo chimiro kana iyo flip-chip chimiro, zvakanakira iyo yakamira chimiro mune imwe. zvinhu zviri pachena.
P1.25-P0.6: Zvakanakira zvina zvinomira pachena
Lattice yakaenzanisa mashandiro eLattice's vertical 5 × 5mil chips uye JD formal 5 × 6mil machipisi kuburikidza nekuedza.Mhedzisiro yacho inoratidza kuti kana tichienzanisa nemachipisi akaiswa pamberi, machipisi akatwasuka haana mwenje wekudivi nekuda kwechiedza chedivi rimwe.Pane kukanganiswa kwechiedza kushoma sezvo nzvimbo inova diki.Mune mamwe mazwi, iyo diki yenzwi, kuderera kuderera kwekupenya.Naizvozvo, vertical machipisi ane zviripachena mabhenefiti mukupenya kwakasimba uye anoratidza kujeka padiki diki.
Kunyanya, iyo vertical chip ine chiedza chakajeka chinobudisa chimiro, yunifomu chiedza chinobuda, nyore kugovera chiedza, uye yakanaka kupisa kupisa kushanda, saka mhedzisiro yekuratidzira yakajeka;uyezve, iyo vertical electrode chimiro, kugovera kwazvino kwakafanana, uye IV curve inowirirana.Maelectrodes ari kudivi rimwe chete, pane kuvharika kwemazuva ano, uye kufanana kwenzvimbo yechiedza hakuna kunaka.Panyaya yegoho rekugadzira, iyo yakamira dhizaini inogona kuchengetedza waya mbiri kana ichienzaniswa neyakajairwa chimiro, uye iyo wiring nzvimbo mumudziyo inokwana, iyo inogona kunyatso wedzera kugadzirwa kwechigadzirwa uye kuderedza chiyero chekuremara kwechishandiso. kuita wire bonding nehurongwa hwehukuru.
In ratidza maapplication,chiitiko che "caterpillar" chakagara chiri dambudziko guru kune vanogadzira, uye chikonzero chechiitiko ichi ndechekutama kwesimbi.Kutama kwesimbi kune hukama zvakanyanya netembiricha, hunyoro, mutsauko ungangoita uye electrode zvinhu zvechip, uye zvinonyanya kuoneka muchiratidziro chine gomo diki.Iyo yakazara vertical chip chimiro zvakare ine yakasarudzika mabhenefiti mukugadzirisa kutama kwesimbi.
Kutanga, kureba pakati pemapango akanaka uye asina kunaka eiyo vertical structure chip yakakura kupfuura 135 μm.Nekuda kwechinhambwe chikuru pakati pemapango akanaka uye asina kunaka munzvimbo yepanyama, kunyangwe kana simbi ion kutama kukaitika, mwenje webead hupenyu hweiyo vertical chip inogona kupfuura ka4 nguva kupfuura iyo yeyakachinjika chip, iyo inovandudza zvakanyanya kuvimbika kwechigadzirwa. uye kugadzikana.Zviri nani kuneflexible display.Chechipiri ndechekuti pamusoro peblue-green chip ine vertical structure is all-inert metal electrode Ti/Pt/Au, iyo inonetsa kuti simbi ifambe, uye kuita kwayo kukuru kwakangofanana neyeye red. -light vertical chip.Chechitatu ndechekuti vertical structure chip inoshandisa silver glue, ine good thermal conductivity, uye tembiricha iri mukati memwenje yakadzikira zvakanyanya pane yekumisikidzwa kwayo, iyo inogona kuderedza zvakanyanya kutama kweayoni esimbi.
Panguva ino, muP1.25-P0.9 application, kunyangwe iyo yakajairwa pamberi-yakaiswa mhinduro inotora musika mukuru nekuda kweiyo yakaderera mutengo mukana, iyo flip-chip uye yakatwasuka mhinduro inoita basa guru mukukwirisa-magumo maapplication anofanirwa. pakuita kwavo kwepamusoro.Panyaya yemutengo, mutengo weboka reRGB machipisi mune yakamira mhinduro ndeye 1/2 iyo yeflip-chip mhinduro, saka mutengo wekuita weiyo vertical chimiro chakakwira.
MuP0.6-P0.9mm zvikumbiro, zvakajairwa kumberi-kumberi zvigadziriso zvinoganhurirwa nenzvimbo inoganhurwa, zvakaoma kuvimbisa goho, uye mukana wekugadzirwa kwehuwandu hwakaderera, nepo flip-chip uye vertical chip mhinduro dzinogona kusangana ne zvinodiwa.Zvakakosha kucherechedza kuti, kufekitari yekurongedza, inofanirwa kuwedzera huwandu hwakawanda hwemidziyo kutora iyo flip-chip chimiro chechimiro, uye nekuti mapadhi maviri eiyo flip-chip idiki zvakanyanya, chiyero chegoho chesolder paste. welding haina kukwirira, uye kukura kwekurongedza kweiyo vertical chip scheme Yakakwira, iyo iripo yekurongedza.
midziyo yemufekitari inogona kushandiswa zvakafanana, uye mutengo weseti yeRGB yemachipisi akatwasuka ihafu chete yeiyo seti yeRGB yeflip-chips, uye iyo yese mutengo wekuita kweiyo vertical solution zvakare yakakwira kupfuura iyo flip-chip solution.
P0.6-P0.3: Ropafadzo yenzira mbiri huru dzehunyanzvi
Kune P0.6-P0.3 maapplication, Lattice inonyanya kutarisisa kune Thin Film LED, yakaonda firimu chip tekinoroji isina substrate, inovhara yakatwasuka chimiro uye flip chip chimiro.Firimu diki re LED rinowanzo reva firimu rakatetepa re LED chip rakabviswa kubva mu substrate.Mushure mekunge substrate yabviswa, substrate itsva inogona kusungirirwa kana chimiro chakatwasuka chinogona kuitwa pasina kusungira substrate.Inonzi Vertical thin film, kana kuti VTF kwenguva pfupi.Panguva imwecheteyo, inogonawo kugadzirwa kuita flip-chip chimiro pasina kubatanidza iyo substrate, iyo inonzi yakaonda firimu flip chip, kana TFFC kwenguva pfupi.
Nzira yehunyanzvi 1: VTF/TFFC chip + quantum dot red light (QD + bhuruu mwenje InGaN LED)
Pasi peiyo yakanyanya kudiki chip saizi, iyo yechinyakare AlGaInP tsvuku LED ine isina kunaka michina zvimiro mushure meiyo substrate yabviswa, uye zviri nyore kwazvo kutyora panguva yekufambisa, zvichiita kuti zviome kuita inotevera misa kugadzirwa.Naizvozvo, imwe mhinduro ndeye kushandisa kudhinda, kupfapfaidza, kudhinda uye mamwe matekinoroji kuisa quantum dots pamusoro peGaN blue LEDs kuti uwane ma LED matsvuku.
Technical Route 2: InGaN LEDs anoshandiswa mune ese RGB mavara
Nekuda kwekusakwana kwesimba remagetsi eiyo iripo quaternary red light mushure mekubvisa iyo substrate, zvakaoma kuita inotevera process kugadzirwa.Imwe mhinduro ndeyekuti mavara matatu eRGB ese ari InGaN LEDs, uye panguva imwechete ziva kubatana kwe epitaxy uye chip kugadzira.Sekureva kwemishumo, Jingneng akatanga tsvakiridzo nekuvandudza gallium nitride dzvuku mwenje pasilicon substrates, uye zvimwe zvakabudirira zvakaitwa musilicon-based InGaN red light LEDs, zvichiita kuti hunyanzvi uhu huvepo.
Zvakakosha kucherechedza kuti, nekuenzanisa zvakanakira nekuipira kweTFFC, FC, uye Micro machipisi maererano ne substrate, kupatsanurwa kwechip, kugona kupenya, uye kutamiswa kwevanhu vakawanda, Lattice akasvika pamhedziso: kushandisa Micro's technical nzira uye Lattice's Kusanganiswa kwe Mini machipisi anogona kuderedza zvakanyanya mutengo wechip uku achidzikisa kuoma kwehunyanzvi.Izvi zvinoreva zvakare kuti 4K uye 8K Mini Ultra-yakakwirira-tsanangudzo LED hombe-screen zvigadzirwa zvinotarisirwa kupinda zviuru zvedzimba.
Parizvino, 4K uye 8K Mini yekupedzisira-yepamusoro-tsanangudzo inoratidzira masikirini mahombe haagone kumiswa inofambiswa ne5G tekinoroji, uye silicon substrate yakatwasuka Mini LED machipisi ane mukana wekuva super-inoshanda-inoshanda chiedza sosi mhinduro.
