Abstract

This paper presents the design, fabrication and measurement of an electrostatic scanning micromirror having a diaphragm mirror plate supported by an array of diamond shaped frame structures. Instead of supporting the diaphragm mirror of different material with stiff rim structure at the circumference, the diaphragm mirror plate and the frame structure are fabricated monolithically in the same layer of single-crystal-silicon[1]. The scanning micromirror with 10μm-thick diaphragm mirror plate, having a planar dimension of 1.5×1.5mm2, supported by an array of 110μm-thick rhombic stiffening frame, was fabricated and tested. Mechanical deflection angle of 8.5° at resonance frequency of 19.55kHz and 44% reduction of dynamic deformation[2], in comparison to the conventional rectangular parallelepiped micromirror, were obtained.
