Abstract:
1. A method of fabricating a MEMS actuator, comprising: forming a curved surface in a first side of a profile-transferring substrate, the first side of the profile-transferring substrate including a planar surface surrounding the curved surface; forming a recess in a second side of the profile-transferring substrate opposite the first side, wherein the recess and the curved surface are aligned; depositing an etch stop layer on the first side of the profile-transferring substrate, the etch stop layer covering at least the curved surface of the profile-transferring substrate; depositing a piezoelectric layer on the etch stop layer, the piezoelectric layer covering at least the curved surface of the profile-transferring substrate; and from the second side of the profile-transferring substrate, etching the profile-transferring substrate in the recess to expose the etch stop layer.
