    Abstract: A method for fabricating a membrane having a corrugated, multi-layer structure, comprising the steps of: providing a substrate having an insulator layer on the top surface of the substrate, a conductive layer on the insulator layer, a sacrificial layer on said conductive layer, and a second conductive layer; patterning a series of holes the second conductive layer to allow release etchant to have access to a second sacrificial layer; depositing the second sacrificial layer onto said second conductive layer so that the series of holes are filled with the second sacrificial layer; patterning the second sacrificial layer with a radial and/or concentric grid pattern so that a third conductive layer when deposited will form the support structure and top portion of the corrugated structure; depositing the third conductive layer so that the grid pattern is filled in and is in contact with the second conductive layer; removing the first and second sacrificial layer by immersing the device in a release etchant.

    Abstract: A laminated structure includes a wafer member with a membrane attached thereto, the membrane being formed of substantially hydrogen-free boron nitride having a nominal composition B.sub.3 N. The structure may be a component in a mechanical device for effecting a mechanical function, or the membrane may form a masking layer on the wafer. The structure includes a body formed of at least two wafer members laminated together with a cavity formed therebetween, with the boron nitride membrane extending into the cavity so as to provide the structural component such as a support for a heating element or a membrane in a gas valve. In another aspect borom is selectively diffused from the boron nitride into a surface of a silicon wafer. The surface is then exposed to EDP etchant to which the diffusion layer is resistant, thereby forming a channel the wafer member with smooth walls for fluid flow.
