Patent ID: 8288204

Claim:
A method for fabricating silicon components with precise dimension control, the process comprising: providing a workpiece comprising a top layer of silicon and a bottom layer of silicon separated by a first layer of SiOx, where each of the three layers has about a same length and a same width; removing edge portions of the top layer, thereby exposing portions of the first layer of SiOx; etching the exposed portions of the first SiOx layer and portions of the first SiOx layer disposed between the top layer and the bottom layer, thereby forming undercut sections between the top layer and the bottom layer; growing a second layer of SiOx having a preselected thickness on the workpiece; depositing a metal on the workpiece such that the metal deposited on the top layer is not continuous with the metal deposited on the bottom layer; and removing the bottom layer and a portion of the first layer of SiOx having a preselected thickness.
