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.

Abstract: To reduce the number of photomasks which are used to form sacrificial layers for producing spaces of a microstructure, thereby reducing the manufacturing cost. Sacrificial layers are formed by using resist masks which are patterned with the same photomask. Specifically, after forming a first sacrificial layer by etching using a resist mask, a second sacrificial layer is formed by etching using a resist mask which is pattered with same photomask as the resist mask of the first sacrificial layer. By deforming one of the resist masks before etching its corresponding sacrificial layer, for example by increasing or reducing the external dimension of the resist mask, sacrificial layers having different sizes from each other can be formed.

Abstract: Since a conventional pollen sensor performs detection in an optical manner, there has been a problem that long time is required for the measurement. Further, it has also been a problem that a light source or a detector is required to be used, and the device has become larger. Correspondingly, it is an object to provide a compact sensor with which particles floating in the air can be easily detected. A sensor having a microstructure which detects a detection object by contact is used. A microstructure has an opening to be a detection hole corresponding to the size of a detection object, and a pair of electrodes having a bridge structure are provided thereabove or thereunder so as to partially contact with each other.

A three-dimensional structure typified by a cantilever is formed by using a mask having a nonuniform thickness. Specifically, a microstructure is manufactured by processing a structural layer formed over a sacrificial layer by using a mask having a nonuniform thickness and then removing the sacrificial layer. The sacrificial layer can be formed by using a silicon layer or a metal layer.
