Abstract:
1. A method of forming a film stack in an integrated circuit, comprising: depositing a layer of silicon carbide adjacent a first layer of dielectric material; depositing a layer of silicon nitride adjacent the layer of silicon carbide; and depositing a layer of high density oxide film having a thickness of at least one kilo-angstrom adjacent the layer of silicon nitride, wherein depositing the layer of silicon carbide adjacent the first layer of dielectric material comprises depositing the layer of silicon carbide in contact with a layer of organo-silicate glass, wherein an adhesive strength between the organo-silicate glass and the silicon carbide reduces delamination defects in the integrated circuit and depositing the layer of silicon nitride adjacent the layer of silicon carbide reduces via-stress migration in the integrated circuit.
