PAM-XIAMEN can supply semiconductor wafers, more wafer specifications please refer to https://www.powerwaywafer.com/products.html. If necessary, we will offer PL (photoluminescence) spectroscopy for the semiconductor wafers. 1. What is PL? About PL, it refers to the self-emission light produced by a material after being excited by light. When a substance absorbs photons and [...]
Silicon carbide (SiC) wafer are available, for more wafer information please click https://www.powerwaywafer.com/sic-wafer. The performance of SiC wafer slicing determines the processing level of subsequent thinning and polishing. Slicing is prone to cracks on the surface and subsurface of the SiC wafer, increasing the fragmentation rate and manufacturing cost [...]
III-nitrides are suitable for working in extreme conditions due to their excellent radiation hardness and high temperature properties. Therein, the fabrication of various types of GaN-based photodetectors (PDs) has been reported over the past decade. In addition, the high conductivity of silicon substrate has drawn attention to the construction [...]

We can supply GaAs laser diode wafer for a wavelength of 940nm. Moreover, a variety of laser wafers with different wavelengths can be offered, more please [...]
How is silicon carbide (SiC) chip made? Generally speaking, chips are semi-finished products that have been cut from wafers. PAM-XIAMEN can offer SiC wafers for making chips, more specifications please refer to https://www.powerwaywafer.com/sic-wafer. Each wafer integrates hundreds of chips, and each chip consists of thousands of cells. So, how [...]
HEMTs evolved from Field Effect Transistors (FETs) are suitable for manufacturing monolithic microwave integrated circuits (MMICs). HEMTs were initially generated to obtain high electron mobility in semiconductor devices at room temperature. The electron mobility of FETs is limited even with high doping levels, so high electron mobility obtained with AlxGa1-xAs/GaAs [...]
InP-based three-terminal electronic devices mainly include InP-based heterojunction bipolar transistors (HBTs) and high electron mobility transistors (HEMTs). PAM-XIAMEN can provide indium phosphide (InP) HEMT epi wafer, in which InGaAs use as the channel material and InAlAs as the barrier layer. The InP HEMT structure grown with InAlAs/InGaAs material system [...]
