Abstract:
A method for manufacturing a MEMS device includes a hole forming step of forming a plurality of holes concaved from a principal surface in a substrate material including a semiconductor, a connecting-hollow-portion forming step of forming a connecting hollow portion that connects the plurality of holes together, and a movable-portion forming step of, by partially moving the semiconductor of the substrate material so as to close at least one part of the plurality of holes, forming a hollow portion that exists inside the substrate material and a movable portion that coincides with the hollow portion when viewed in a thickness direction of the substrate material.

Claim (Index 11):
The method for manufacturing a MEMS device according to  claim 1 , wherein the substrate material has a first layer that is made of a semiconductor and that forms the principal surface, a third layer made of a semiconductor, and a second layer that is interposed between the first layer and the third layer and that is made of a material different from a semiconductor, and wherein the plurality of holes that pass through the first layer and that use the second layer as each bottom surface of the plurality of holes are formed by use of the substrate material in the hole forming step,\n the method further comprising: a protective-film forming step of forming a protective film with which the principal surface and inner side surfaces and bottom surfaces of the plurality of holes are covered; and a through-hole forming step of forming a plurality of through-holes that pass through the protective film and through the second layer by removing only a part of the protective film with which the bottom surfaces of the plurality of holes and a part of the second layer that forms the bottom surfaces are covered; the protective-film forming step and the through-hole forming step being performed after the hole forming step and before the connecting-hollow-portion forming step, wherein the connecting hollow portion is formed by performing etching through the plurality of through-holes in the connecting-hollow-portion forming step.
