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:The ideal waverlength for us is 465 nm, can you offer?. A:It is no problem, but you should know the wavelength should be a range, what we will offer you 465+/-2nm.
Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs? A:Yes, we can offer 850nm or 620nm for 4” size.
Q:Our application is for microwave annealing. Therefore, the silicon carbide must be able to absorb microwaves? A:Since the dielectric constant of 6H and 4H are large, so if SiC wafer is as absorbing materials, mainly to achieve through the structure design of Electromagnetic match.I don’t [...]
Q : does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project. A:Sorry, we can not offer fabrication of p and n [...]
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: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 [...]
