A method for fabricating a semiconductor device includes forming an isolation layer which defines an active region in a substrate, forming recess patterns in the active region and the isolation layer, baking a surface of the recess pattern by conducting an annealing process and forming a gate dielectric layer over a surface of the recess pattern by conducting an oxidation process. Similarly, a Wyner-Ziv decoder may be realized by: applying an asymmetric Slepian-Wolf decoder to compressed input data using side information to generate intermediate values, and jointly decoding the intermediate values using the side information to generate decompressed output data. The first terminal and the second terminal are staggered with respect to each other, the second terminal and the third terminal are staggered with respect to each other, and the third terminal and the fourth terminal are staggered with respect to each other. Often, a designer will document what the timing looks like by using a comment field; dashes and underscore characters make great looking timing diagrams when a fixed width font is used. The perimeter of the first lower surface is larger than the perimeter of the second raised upper surface such that a lip is formed between the first lower surface and the second raised upper surface.
