    摘要: An integrated circuit structure includes a substrate having a top surface; a first conductive layer over and contacting the top surface of the substrate; a dielectric layer over and contacting the first conductive layer, wherein the dielectric layer includes an opening exposing a portion of the first conductive layer; and a proof-mass in the opening and including a second conductive layer at a bottom of the proof-mass. The second conductive layer is spaced apart from the portion of the first conductive layer by an air space. Springs anchor the proof-mass to portions of the dielectric layer encircling the opening. The springs are configured to allow the proof-mass to make three-dimensional movements.

    摘要: System and method for forming a structure including a MEMS device structure. In order to prevent warpage of a substrate arising from curing process for a sacrificial material (such as a photoresist), and from subsequent high temperature process steps, an improved sacrificial material comprises (i) a polymer and (ii) a foaming agent or special function group. The structure can be formed by forming a trench in a substrate and filling the trench with a sacrificial material. The sacrificial material includes (i) a polymer and (ii) a foaming agent or special function group. After further process steps are completed, the sacrificial material is removed from the trench.

    摘要: A metal-ceramic multilayer structure is provided. The underlying layers of the metal/ceramic multilayer structure have sloped sidewalls such that cracking of the metal-ceramic multilayer structure may be reduced or eliminated. In an embodiment, a layer immediately underlying the metal-ceramic multilayer has sidewalls sloped less than 75 degrees. Subsequent layers underlying the layer immediately underlying the metal/ceramic layer have sidewalls sloped greater than 75 degrees. In this manner, less stress is applied to the overlying metal/ceramic layer, particularly in the corners, thereby reducing the cracking of the metal-ceramic multilayer. The metal/ceramic multilayer structure includes one or more alternating layers of a metal seed layer and a ceramic layer.
