2 inch 50.8mm Sapphire Wafer C-Diyaarad M-diyaarad R-diyaarad A-diyaarad Dhumucdiisuna tahay 350um 430um 500um
Tilmaamaha hanuuninta kala duwan

Hantida jirka | dhidibka C waxa uu leeyahay nal crystal ah, faasasyada kalena waxay leeyihiin iftiin taban. Diyaaradda C waa fidsan tahay, oo ay doorbidayso in la gooyo. | R-diyaarad inyar ka adag A. | Diyaaradda M ayaa lagu talaabsan karaa silig, ma fududa in la gooyo, fududahay in la gooyo. | Qalafsanaanta A-diyaaradaha ayaa si weyn uga sarreeya kan diyaaradda C-diyaarad, taas oo lagu muujiyo caabbinta xidhashada, caabbinta xoqan iyo adkaanta sare; Side A-diyaarad waa diyaarad zigzag ah, taas oo ay fududahay in la gooyo; | ||
Codsiyada | Qaybaha sapphire-ka ee C-oriented ayaa loo isticmaalaa si ay u koraan III-V iyo II-VI filimada kaydka ah, sida gallium nitride, kaas oo soo saari kara alaabta LED buluug, diodes laser, iyo codsiyada infrared detector. | Kobaca substrate ku jihaysan ee kala duwan ee silikoon extrasystals oo kaydsan, oo loo isticmaalo microelectronics wareegyada isku dhafan. | Waxaa inta badan loo isticmaalaa in lagu beero filimaanta Epitaxial GaN ee aan polar/semi-polar-ka ahayn si loo horumariyo waxtarka iftiinka. | A-ujeeda substrate-ka waxay soo saartaa ogolaansho/dhexdhexaad isku mid ah, iyo heer sare oo dahaar ah ayaa loo adeegsadaa tignoolajiyada isku-dhafka ah ee microelectronics. Heerkulka sare ee heerkulka sare ayaa laga soo saari karaa kiristaalo dhaadheer oo A-sal ah. | ||
Awooda farsamaynta | Qaabka Sapphire Substrate (PSS): Qaabka Kobaca ama Etching, nanoscale qaabab gaar ah oo qaab-dhismeedka microstructure caadiga ah ayaa loo qaabeeyey oo lagu sameeyay substrate sapphire si loo xakameeyo qaabka wax soo saarka iftiinka LED-ka, loona yareeyo cilladaha kala duwan ee GaN ee ku koraya substrate-ka sapphire , wanaajiso tayada epitaxy, oo kor u qaad waxtarka tirada gudaha ee LED-ka iyo kordhinta waxtarka iftiinka iftiinka. Intaa waxaa dheer, sapphire priism, muraayad, muraayad, dalool, koontada iyo qaybaha kale ee qaabdhismeedka ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha. | |||||
