Abstract
A method of forming a semiconductor device includes forming active circuitry over a semiconductor substrate, wherein the semiconductor substrate has a first major surface and a second major surface and the first active circuitry is formed over the first major surface of the semiconductor substrate. A via is formed within the first semiconductor substrate, wherein the via extends from the first active circuitry to the second major surface of the first semiconductor substrate. A dielectric layer is formed over the second major surface and adjacent the first via. The dielectric layer may include nitrogen and silicon and may be formed by a low pressure, low temperature, or both plasma process.
