Abstract
The present invention provides a MEMS and a sensor having the MEMS which can be formed without a process of etching a sacrifice layer. The MEMS and the sensor having the MEMS are formed by forming an interspace using a spacer layer. In the MEMS in which an interspace is formed using a spacer layer, a process for forming a sacrifice layer and an etching process of the sacrifice layer are not required. As a result, there is no restriction on the etching time, and thus the yield can be improved.
