description A method and system for deprocessing a semiconductor device is disclosed. The semiconductor device has a plurality of structures and an intermetal dielectric layer. The method and system include anisotropically plasma etching the intermetal dielectric layer at an oblique angle and rotating the semiconductor device during the plasma etch to reduce or eliminate build up of a material on the plurality of structures due to the plasma etch of the intermetal dielectric layer. In another aspect the method and system include a semiconductor device deprocessed using the method in accordance with the present invention. In another aspect, the present invention includes a system for deprocessing the semiconductor device.
