Patent ID: 6922270

Claim:
A multi-step landing micro-mirror, comprising: a trench formed in a substrate and having N−1 steps in one side wall thereof; N plates rotated in or on said trench; and 2N springs for connecting said plates to each other; wherein said N plates are composed of an outermost first plate, a second plate connected with said first plate by the spring and located in said first plate, . . . , and a N-th plate connected with a (N−1)-th plate by the spring and located in said (N−1)-th plate, wherein N is an integer and equal or greater than 2, and wherein when voltages are applied to said N plates and said trench, respectively, said first plate is subjected to a first landing with a predetermined displacement angle on a first step of said trench due to the electrostatic force, said second plate is subjected to a second landing with the predetermined displacement angle on a second step of said trench, . . . , said N-th plate is subjected to a N-th landing with the predetermined displacement angle on the other side wall of said trench.
