Dummy grade silicon wafers perform very efficiently for experimental and testing projects. These wafers are different from all other silicon wafer grades. They are mostly used in the production line for safety improvements in the entire production process. They are also used to ensure and evaluate the production processes. Dummy wafers are used to measure the pressure resistance, film thickness, pinball presence and reflection index in the entire production process.
Found in 1990, Xiamen Powerway Advanced Material Co., Ltd (PAM-XIAMEN) is a leading manufacturer of semiconductor material in China. PAM-XIAMEN develops advanced crystal growth and epitaxy technologies, manufacturing processes, engineered substrates and semiconductor devices. PAM-XIAMEN’s technologies enable higher performance and lower cost manufacturing of semiconductor wafer.
Before 1990, we are stated owned condensed matter physics research center. In 1990, center launched Xiamen Powerway Advanced Material Co., Ltd (PAM-XIAMEN), now it is a leading manufacturer of compound semiconductor material in China.
