Patent ID: 6977212

Claim:
A method of fabricating semiconductor device comprising the steps of: a) selecting a substrate having a front side and a back side; b) applying a BCB layer on the front side of the substrate; c) producing an oxide layer or any other suitable layer on the front of the substrate between the BCB layer and the substrate; d) fully curing the BCB layer, wherein the method of fully curing the BCB layer comprises the steps of: i) baking the BCB layer until the BCB layer is partially cured; and ii) baking the BCB layer until the BCB layer is fully cured; e) processing the semiconductor using a process selected from the group of processes composed of grinding, vapor deposition, defining patterns in the substrate, any other suitable semiconductor fabrication technique, and any combination thereof; f) stressing the substrate; g) wet etching the BCB layer, wherein wet etching of the BCB layer is performed using a chemical etch selected from the group of chemical etches composed of hydrogen fluoride, nitric acid, sulfuric acid and phosphoric acid or any combination thereof; h) removing the BCB layer from the substrate; and i) removing the oxide layer from the substrate.
