Abstract: Processes are provided herein for the fabrication of MEMS utilizing both a primary metal that is integrated into the final MEMS structure and two or more sacrificial secondary metals that provide structural support for the primary metal component during machining. A first secondary metal is thinly plated around the primarj metal and over the entire surface of the substrate without using photolithography. A second secondary metal, is then thickly plated over the deposited first secondary metal without using photolithography. Additionally, techniques are disclosed to increase the deposition rate of the first secondary metal between primary metal features in order to prevent voiding and thus enhance structural support of the primary metal during machining.

Abstract: The formation of a MIM (metal insulator metal) capacitor (164) and concurrent formation of a resistor (166) is disclosed. A copper diffusion barrier is formed over a copper deposition (110) that serves as a bottom electrode (170) of the capacitor (164). The copper diffusion barrier mitigates unwanted diffusion of copper from the copper deposition (110), and is formed via electro-less deposition such that little to none of the barrier material is deposited at locations other than over a top surface of the deposition of copper/bottom electrode. Subsequently, layers of dielectric (150) and conductive (152) materials are applied to form a dielectric (172) and top electrode (174) of the MIM capacitor (164), respectively, where the layer of conductive top electrode material (152) also functions to concurrently develop the resistor (166) on the same chip as the capacitor (164).
