| 摘要 |
The present invention provides a MEMS device in which a warp that is deformation of a beam is reduced and which aims to improve the characteristic thereof, a method for manufacturing the MEMS device and a diffraction-type MEMS device. <??>The MEMS device of the present invention includes a substrate-side electrode and a beam driven by a static electricity generated between the substrate-side and the beam, in which the beam is formed of a plurality of thin films including a driving-side electrode and is provided with deformation prevention means for preventing the deformation of the beam due to the warp of thin films caused by film stress. <??>The diffraction-type MEMS device of the present invention is configured such that in the above-described configuration the substrate-side electrode is made common and a plurality of beams are provided independently to each other so as to be opposed to the substrate electrode. <IMAGE>
