This prоblem deаls with fоrming а diаphragm made оf p++ boron-doped silicon. A (100) silicon wafer with a thickness of 200μm is doped on one side with boron to a depth of 20μm. The whole wafer is then covered with an oxide layer and a square opening is formed on the backside of the wafer as shown. The side length of the square opening is 1000μm as shown. The square opening is misaligned with respect to the direction that is typically indicated by the major flat of a (100) wafer by 10°, as shown in the drawing to the right of the figure where the view looking at the bottom of the wafer is shown. The wafer is now dropped in an anisotropic silicon etchant (i.e. EDP or KOH) and etched until the etch stops on the p++ region and forms a suspended p++ diaphragm. Note that the etch-stop can be assumed to be perfect, and you can assume that the (100) surface, and all other planes, etch at a nominal etch rate, but the (111) planes do not etch at all. Calculate the EXACT side dimension of the square diaphragm formed by the p++ layer. (Hint: Please note that (111) planes and (100) wafer intercept at directions that are either in parallel or perpendicular to the flat (also known as the major flat of the wafer. In other words, it is to be anticipated for the feature to be suspended with an undercut if its edge was not aligned with a line direction. The rest of the problem shall be quite similar to Problem #2)
