Method of foming a micromechanical structure

摘要

A method of forming a micromechanical structure, wherein at least one micromechanical structural layer is provided above a substrate. The micromechanical structural layer is sustained between a lower sacrificial silicon layer and an upper sacrificial silicon layer, wherein a metal silicide layer is formed between the lower and upper sacrificial silicon layers to increase interface adhesion therebetween. The upper sacrificial silicon layer, the metal silicide layer and the lower sacrificial silicon layer are then removed to release the micromechanical structural layer.
