Torsion spring for MEMS structure

摘要

A torsion spring for a micro-electro-mechanical system (MEMS) structure is provided. The torsion spring is connected between a pivoting member and a fixed member and supports the pivoting member so that the pivoting member can pivot about the torsion spring. The torsion spring includes: a horizontal beam; at least one vertical beam formed on the horizontal beam; and a plurality of auxiliary beams formed on the horizontal beam and parallel to the vertical beam.
