Dia50.8mm Sapphire Wafer Sapphire Daaqadda Gudbinta Aragga Sare ee DSP/SSP

Sharaxaad Gaaban:

Sababo la xiriira shabag yar oo aan isku mid ahayn iyo guryaha kiimikada iyo jirka ah, sapphire(Al2O3) wafer waa substrates-ka caanka ah ee III-V nitrides, superconductor iyo magnetic epi-film. Waxaa si weyn loogu isticmaalaa GaN iyo korriinka filimka khafiifka ah ee epitaxial, silicon on sapphire, suuqa LED iyo warshadaha indhaha.

Waa maxay sababta Sapphire?

Sifooyinka sapphire crystal-ka ah
1. Sapphire waxay leedahay gudbin sare oo indhaha ah, sidaas darteed waxaa si ballaaran loo isticmaalaa sida qalabka microelectronic tube dielectric, element conduction ultrasonic, waveguide laser cavity, iyo walxaha kale ee indhaha, sida qalabka daaqadaha ee qalabka militariga infrared, baabuurta bannaan, lasers-xoojinta sare iyo indhaha. isgaarsiinta.

2. Sapphire waxay leedahay qallafsanaan sare, xoog sare, heerkulka shaqada sare, caabbinta caabbinta, sifooyinka caabbinta daxalka, sidaas darteed substrate sapphire waxaa inta badan loo isticmaalaa jawi adag, sida cabbirka biyaha kululeeyaha (iska caabbinta heerkulka sare), scanner code code badeecada, xajinta, iyo wax-soo-saarka kale ee saxda ah (iska caabinta xirashada), dhuxusha, gaaska, dareemayaasha si fiican loo ogaanayo iyo daaqadaha wax qabad (anti-corrosion).

3. Sapphire waxay leedahay sifooyinka dahaarka korantada, hufnaanta, conductivity kaamerada wanaagsan, iyo qallafsanaan sare, sidaas darteed waxa loo isticmaali karaa sida maadada substrate ee wareegyada isku dhafan, sida LED iyo microelectronic wareegyada, ultra-sare-xawaaraha isku dhafan.
