Abstract: In a method for forming a semiconductor device photo-sensing regions are formed over a frontside of a substrate. A first layer is formed over a backside of the substrate and is patterned to form a plurality of grid lines. The grid lines can define a plurality of first areas and a plurality of second areas. A second layer may be formed over exposed portions of the backside, the gridlines, the first areas, and the second areas and a third layer may be formed over the second layer. The second and third layer may have different etch rates and the third layer is pattern so as to remove the third layer from over the plurality of first areas.

Abstract: A half tone phase shift mask material, suitable for use at 193 nm is disclosed. It comprises a layer of nitrogen rich silicon nitride that was formed by subjecting a mixture of a nitrogen bearing gas, such as nitrogen and/or ammonia, with a silicon bearing gas, such as silane, to a plasma discharge. Provided the ratio of the nitrogen bearing to the silicon bearing gases is about 10 to 1, films having the required optical properties at 193 nm are formed. These properties are a reflectance that is less than 15% and a transmittance that is between 4 and 15%. Related optical properties, namely an extinction coefficient of about 0.4 and a refractive index of about 2.5, are also closely approached. Additionally, the films are stable under prolonged UV exposure and exhibit good etch behavior.
