摘要: The present disclosure provides a system of fabricating a microstructure device with an improved anchor. A method of fabricating a microstructure device with an improved anchor includes providing a substrate and forming an oxide layer on the substrate. Then, a cavity is etched in the oxide layer, such that the cavity includes a sidewall in the oxide layer. A microstructure device layer is then bonded to the oxide layer over the cavity. Forming a microstructure device, a trench is etched in the device layer to define an outer boundary of the microstructure device. In an embodiment, the outer boundary is substantially outside of the sidewall of the cavity. Then, the sidewall of the cavity is etched away through the trench in the device layer, to thereby suspend the microstructure device over the cavity.
