150mm 200mm 6inch 8inch GaN oo ku yaal Silicon Epi-lakabka wafer Gallium nitride epitaxial wafer

150mm 200mm 6inch 8inj GaN dusha Silicon Epi-Layer wafer Gallium nitride epitaxial wafer Sawirka

Sharaxaad Gaaban:

Waferka 6-inch ee GaN Epi-Layer wafer waa walxo semiconductor tayo sare leh oo ka kooban lakabyo gallium nitride (GaN) oo ku koray substrate silikoon. Maaddadu waxay leedahay sifooyin gaadiid elektaroonig ah oo heer sare ah waxayna ku habboon tahay soo saarista aaladaha semiconductor-ka sare iyo kuwa soo noqnoqda.

Habka wax-soo-saarka

Habka wax-soo-saarku waxa uu ku lug leeyahay koritaannada GaN ee lakabka sapphire iyadoo la isticmaalayo farsamooyin horumarsan sida kaydinta uumiga kiimikada birta-organic (MOCVD) ama molecular beam epitaxy (MBE). Habka dhigista waxaa lagu fuliyaa xaaladaha la xakameeyey si loo hubiyo tayada sare ee crystal iyo filimada lebis.

Codsiyada 6inch GaN-On-Sapphire: Chips substrate sapphire 6-inji ah ayaa si weyn loogu isticmaalaa isgaadhsiinta microwave, nidaamyada radar, tignoolajiyada wireless-ka iyo optoelectronics.

Qaar ka mid ah codsiyada caadiga ah waxaa ka mid ah

1. Cod-weyneeye Rf

2. Warshadaha iftiinka LED

3. Qalabka isgaadhsiinta ee shabakada wireless

4. Qalabka elektarooniga ah ee jawiga heerkulka sare

5. Qalabka Optoelectronic

Tilmaamaha alaabta

- Cabbirka: Dhexroorka substrate-ku waa 6 inji (qiyaastii 150 mm).

- Tayada dusha sare: Dusha sare ayaa si fiican loo qurxiyey si ay u bixiso tayada muraayadda aad u fiican.

- Dhumucda: Dhumucda lakabka GaN waxaa loo habeyn karaa iyadoo loo eegayo shuruudo gaar ah.

- Baakadaha: Substrate-ka waxaa si taxadar leh loogu buuxiyey walxaha lidka ku ah static si looga hortago burburka inta lagu jiro gaadiidka.

- Meelaynta cidhifyada: Substrate-ku wuxuu leeyahay geeso gaar ah oo fududeeya isku-habaynta iyo hawlgalka inta lagu jiro diyaarinta aaladda.

- Halbeegyada kale: Qiyaasaha gaarka ah sida caatada, iska caabbinta iyo feejignaanta doping ayaa lagu hagaajin karaa iyadoo loo eegayo shuruudaha macaamiisha.

Iyada oo leh hantidooda agabka sare iyo codsiyada kala duwan, 6-inch sapphire substrate wafers waa doorasho lagu kalsoonaan karo oo loogu talagalay horumarinta aaladaha wax-qabadka sare leh ee warshadaha kala duwan.
