The InGaAsP material epitaxially grown on the InP substrate is an important material for the fabrication of optoelectronic and microwave devices. The emission wavelength of InGaAsP / InP laser structure covers 1.0-1.7μm, covering two low-loss windows of 1.3μm and 1.55μm for silica fiber communication. Therefore, InGaAsP is widely used in...

Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm? A: Sure, no problem
Q:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC? A: For our semi-insulating SiC substrate, it is V doped, we can not offer High Purity semi-insulating SiC, however we can offer undoped SiC if your quantity is good.
Q:I want to know the dopant concentration of SiC substrate that you normally provide ? What is the maximum Nitrogen dopant concentration that you can provide? I am looking for heavily nitrogen doped SiC wafers? A: Our Nitrogen dopant concentration is 1E18/cm3-1E19/cm3, which belongs to heavy dopant.
Q:Can you offer SiC mono crystal material with high Thermal Conductivity > 490 W/mK, wafers with thickness: 300-1000um for semiconductor devices heat sinks manufacturing? A: Thermal Conductivity> 490 W/mK is theory value of SiC mono, however we tested some wafers, the thermal conductivity is below 450W/mK, which are lower the theory...
Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range? A: We can offer misorientation in low degree, no problem.
