Abstract
A 1500 /spl mu/m/spl times/1200 /spl mu/m scanning mirror having vertical comb fingers has been fabricated by using silicon-on-insulator (SOI)-fabrication processes. It is a vertically driven electrostatic scanner and composed of two structures having vertical comb fingers. We used a buried oxide layer as an etch stop and acquired torsion bars with the uniform thickness. From this, the reliability of the scanning mirror is much improved.
