    摘要: Scratch-resistant coatings for protecting front-side microelectromechanical and semiconductor device features during backside processing are provided, along with methods of using the same. The coatings are non-photosensitive, removable, and tolerate high processing temperatures. These coatings also eliminate the need for a separate etch stop layer in the device design. The coatings are formed from a composition comprising a component dissolved or dispersed in a solvent system. The component is selected from the group consisting of styrene-acrylonitrile copolymers and aromatic sulfone polymers.

    摘要: This invention provides methods of creating via or trench structures on a developer-soluble hardmask layer using a multiple exposure-development process. The hardmask layer is patterned while the imaging layer is developed. After the imaging layer is stripped using organic solvents, the same hardmask can be further patterned using subsequent exposure-development processes. Eventually, the pattern can be transferred to the substrate using an etching process.

    摘要: A transparent two-layer electrostatic dissipating coating includes a first layer comprising a transparent first binder polymer and a first intrinsically conducting polymer (ICP) in an amount sufficient to provide the first layer with a surface resistance of from about 103 to about 105Ω/□; and a second layer in direct contact with the first layer and comprising a transparent second binder polymer and a second ICP in an amount sufficient to provide the second layer with a surface resistance of from about 106 to about 1010Ω/□, wherein the coating has a light transmission of at least about 70% at a wavelength of 600 nm. Methods of making and using the coating are also described.
