Q: What wafer size do you provide with flat sapphire substrate?
A:Currently we still can offer 2″ wafer on flat sapphire substrate.
Q: What wafer size do you provide with flat sapphire substrate?
A:Currently we still can offer 2″ wafer on flat sapphire substrate.
Q:We want to know the refractive index of these SiC wafers? A:The refractive index is no=2.707, ne=2.755
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
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. [...]
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:We request for the following items 1. Silicon (Si) single crystal wafers, polished on one side N-type, orientation<100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 mm 2. Silicon (Si) single crystal wafers, polished on one side P-type, orientation <100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 [...]
Q:Our application will be making micro-pillar arrays based on the MQWs for high brightness LEDs and its wavelength tuning. So we do not really care the emission wavelength you provide but we will mind whether the process and emission wavelength would be consist between [...]
