of the zeta potential. According to colloid chemistry and lots of experiments, this can be achieved by adding surfactants. Nonionic complex surfactant was used as megasonic cleaning solution, and the adsorptive state of particle on Si wafers was effectively controlled. The efficiency and effect of megasonic particle removal is greatly improved. A perfect result is also obtained in wafer cleaning. Key......

: This paper addresses a unified approach of the PID controller design for low as well as high order unstable processes with time delay. The design method is based on the direct synthesis (DS) approach... reference model in the DS scheme. The direct synthesis controller has been approximated to the PID controller using the frequency response matching method. A consistently better performance has been......
