发明名称 Manufacturing method of micro-electro-mechanical device
摘要 A method of forming a microstructure body and a semiconductor element for controlling the microstructure body over the same substrate to reduce manufacturing cost, for mass-production of micromachines having a microstructure. In manufacturing a micromachine, a sacrifice layer is formed using a mask material for forming a pattern of a film, and removal of the mask in a region for forming a semiconductor element and removal of the sacrifice layer and the mask in a region for forming a microstructure body are performed by the same step. Specifically, a manufacturing method of a micro-electro-mechanical device is provided wherein a sacrifice layer is selectively formed over an insulating substrate, a semiconductor layer is formed to cover the sacrifice layer, a mask is formed over the semiconductor layer, the semiconductor layer is etched using the mask, and the mask and the sacrifice layer are removed by the same step.
