Calibration of Wet Etching Parameters for Sacrifice Layer of MEMS

Journal of Computational Science and Technology, 2011
This paper presents a wet etching simulation method for sacrifice layer of MEMS (micro electro mechanical system) that considers physical phenomenon including flow, diffusion and chemical reaction. In this method, a partial differential equation with implicit parameterization of etching properties was studied that was solvable by any commercial CFD ...
