Deformable mirror device and manufacturing method thereof
First Claim
1. A method for manufacturing a deformable mirror device comprising a substrate having an address scanning circuit, a plurality of electrodes formed on the surface of said substrate, a first moving mirror rotatably disposed above said electrodes, a first post for supporting said first moving mirror between said electrodes and said first moving mirror, a second post formed on the surface of said first moving mirror, and a second moving mirror rotatably supported by said second post, the method comprising the steps of:
- forming said second moving mirror in a predetermined pattern on a base;
forming said second post to extend from a surface of said second moving mirror;
forming said first moving mirror on said second post;
forming said first post on said first moving mirror;
forming said electrodes on said first post; and
combining said substrate with an assembly of said first and second moving mirrors, said first and second posts, and said electrodes.

Abstract
A deformable mirror device and a manufacturing method thereof, which decreases the possibility of damage to a substrate having an address scanning circuit and increases the efficiency of light reflection of a moving mirror. First and second moving mirrors and first and second posts are fabricated on a substrate. An address scanning circuit (SRAM) is fabricated on another substrate, independently. Finally, both the substrates are combined. The second post is vertically formed by sputtering after the second moving mirror is formed.
