A method of fabricating a micro-electromechanical system (MEMS) device from a complementary metal oxide semiconductor (CMOS) having a silicon layer and an oxide layer, the oxide layer being on the silicon layer and containing at least one metal layer. The method includes etching the silicon layer of the CMOS to form a trench through the silicon layer to expose a portion of the oxide layer. The method also includes depositing a silicon oxide layer on the silicon layer and on an exposed portion of the oxide layer within the trench. Additionally, the method includes etching the silicon oxide layer deposited on the exposed portion of the oxide layer to expose a portion of the metal within the oxide layer. The method further includes electrodepositing a conductor within the trench such that the conductor extends through the trench to the exposed portion of the metal and etching the silicon layer of the CMOS to remove portions of the silicon layer adjacent the conductor.
