Abstract: Provided is a method including at least the thermal treatment step of thermally treating a SOI substrate having a first silicon layer at a first temperature that the diffusion flow rate of an interstitial silicon atom in a silicon single crystal is higher than the diffusion flow rate of an interstitial oxygen atom and the processing step of processing the SOI substrate after the thermal treatment step to obtain a displacement enlarging mechanism.

Abstract: At the first etching step of etching an SOI substrate from a first silicon layer side, a portion of a first structure formed of the first silicon layer is formed as a pre-structure having a larger shape than a final shape. At the mask formation step of forming a final mask on a second silicon layer side of the SOI substrate, a first mask corresponding to the final shape of the first structure is formed in the pre-structure. At the second etching step of etching the SOI substrate from the second silicon layer side, the second silicon layer and the pre-structure are, using the first mask, etched to form the final shape of the first structure.
