Abstract:
A microfabrication process for fabricating a microelectromechanical systems device, comprising:depositing one or a stack of layers on a substrate; patterning said one or a stack of layers to form a plurality of longitudinally extending groves therein; depositing a middle layer on said one or a stack of layers; patterning the middle layer using said one or a stack of layers as a photomask, wherein said middle layer is exposed to light passed through the groves in the one or a stack of layers; and developing said middle layer to form longitudinally spaced ridges in the said middle layer disposed in the groves in said one or a stack of layers, said ridges forming a support structure which is part of the microelectromechanical systems device.
