Gallium Arsenide VGF and LEC Grown

We have Gallium Arsenide Wafers (GaAs) III-V direct band gap semiconductor that are both the commonly used Vertical Gradient Freeze (VGF) and also Liquid encapsulated Czochralski (LEC) grown high-purity single crystal that are semi-insulating.

Gallium Arsenide Elements

 

Recently a researcher inquired about 150mm Gallium Arsenide with Chromium (Cr) doping.

Client request:

We are biding projects demanding around 20 pcs chromium-doped 6" GaAs wafers and 5~10pcs 4" Silicon-on-Sapphire(SOS) wafers. Can you offer these items?If yes, I will send you detailed specification.

Our Reply:

We do have the technology and equipment to make SI GaAs:Cr even in 150mm diameter.

How? A new crystal ingot would have to be grown and then sliced and polished into wafers. With Ro>1E8 Ohmcm, mobility >5,000cm²/Vs is unattainable, but we can probably reach u>4,000²/Vs. Likewise EPD<500/cm² is unrealistic for LEC process, but we can certainly achieve 5E4/cm². To dope with Chromium, we have to use the LEC rather than the VGF process.

Gallium Arsenide Wafers Benefits Over Silicon

Two benefits of GaAs wafers over Silicon wafers are:2 inch gallium arsenide wafer

1) GaAs moves electrons faster while consuming less power. Think of your cell phone. Tight spaces and short battery life. GaAs provides a real advantage over silicon for some components.

2) GaAs has direct band-gap properties make all-optical buses direct light on-chips more efficiently than wires do on silicon.

We supply GaAs wafers up to 150mm in diameter. Below are just a small sample.
