Patent ID: 8581355

Claim:
A micro electric mechanical system device, comprising: a substrate; an island-shaped first insulating layer formed by coating a liquid insulating material on the substrate and patterning; a second insulating film formed on the top and side surfaces of the island-shaped first insulating layer, and having a thickness smaller than that of the island-shaped first insulating layer; a metal layer formed on a top surface of the second insulating film in an island-shaped region where the island-shaped first insulating layer is formed; a third insulating film formed on the top of the metal layer and on an area of the second insulating film in correspondence with the top and side surfaces of the island-shaped first insulating layer; and a micro electric mechanical system element including a supporting portion and movable portion, the movable portion being raised above the metal layer such that a gap is formed therebetween, and the supporting portion supporting the movable portion and being connected to the metal layer.
