150mm 200mm 6inch 8inch GaN akan Silicon Epi-Layer wafer Gallium nitride epitaxial wafer
Hanyar masana'anta
Tsarin masana'anta ya haɗa da haɓaka yadudduka na GaN akan ma'aunin sapphire ta amfani da ingantattun fasahohi kamar ƙarfe-kwakwalwar sinadari na tururi (MOCVD) ko molecular beam epitaxy (MBE). Ana aiwatar da tsarin ƙaddamarwa a ƙarƙashin yanayin sarrafawa don tabbatar da ingancin kristal da kuma fim ɗin uniform.
6inch GaN-On-Sapphire aikace-aikacen: 6-inch sapphire substrate chips ana amfani da su sosai a cikin sadarwar microwave, tsarin radar, fasaha mara waya da optoelectronics.
Wasu aikace-aikacen gama gari sun haɗa da
1. Rf ikon amplifier
2. LED lighting masana'antu
3. Kayan aikin sadarwa mara waya
4. Na'urorin lantarki a cikin yanayin zafi mai zafi
5. Optoelectronic na'urorin
