  • Patent number: 11268928
    Abstract: Apparatus and associated methods relate to a compact gas sensor (CGS) including a housing with a central stepped cavity with one or more first lead contact(s) forming a portion of a base plane in a bottom of the cavity and one or more second lead contact(s) forming a portion of a stepped plane higher than the base plane, the cavity sized to receive a chemically based stack of material made up of a bottom diffusion electrode layer, a middle electrolyte gel layer, and a top diffusion electrode layer. The bottom diffusion electrode layer is in electrical contact with the first lead contact(s). The top diffusion electrode layer electrically couples to the second lead contact(s) via an overlaying micro electromechanical system (MEMS) element layer with conductive coating. In an illustrative example, the CGS may provide gas sensing in small spaces.

  • Publication number: 20090001594
    Abstract: A method may comprise assembling a first dielectric ensemble that comprises a first dielectric layer exhibiting a first porosity, a second dielectric layer exhibiting a second porosity and a third dielectric layer exhibiting a third porosity, and fabricating a first metal line in the dielectric ensemble. A chemical may be applied on the third layer to pass through and dissolve a portion of the second layer. The third layer acts to prevent a via that is partially landed on the dielectric from exposing the air gap underneath.

  • Publication number: 20080220380
    Abstract: Electric fields may be advantageously used in various steps of photolithographic processes. For example, prior to the pre-exposure bake, photoresists that have been spun-on the wafer may be exposed to an electric field to orient aggregates or other components within the unexposed photoresist. By aligning these aggregates or other components with the electric field, line edge roughness may be reduced, for example in connection with 193 nanometer photoresist. Likewise, during exposure, electric fields may be applied through uniquely situated electrodes or using a radio frequency coil. In addition, electric fields may be applied at virtually any point in the photolithography process by depositing a conductive electrode, which is subsequently removed during development. Finally, electric fields may be applied during the developing process to improve line edge roughness.

  • Patent number: 7335586
    Abstract: A method for sealing a porous dielectric layer atop a substrate, wherein the dielectric layer is patterned to form at least a trench and at least a via, comprises applying a first plasma to a surface of the dielectric layer to silanolize the surface, treating the surface of the dielectric layer with a silazane to form a monolayer of silane molecules on the surface, and applying a second plasma to the surface of the dielectric layer to induce a polymerization of at least a portion of the silane molecules. The polymerized silane molecules form a cross-linked matrix that builds over a substantial portion of the surface of the dielectric layer and seals at least some of the exposed pores.
