Patent number: 7452818
Abstract: The disclosure provides a method for manufacturing a semiconductor device. The method, in one embodiment, includes forming semiconductor features (405, 410, 415, 420, 425, 430, 435, 440, 445) over a substrate (310), and then forming a layer of material (510) over the semiconductor features (405, 410, 415, 420, 425, 430, 435, 440, 445). This method further includes selectively etching portions of the layer of material (510) based upon a density or size of the semiconductor features (405, 410, 415, 420, 425, 430, 435, 440, 445) located thereunder, and then polishing remaining portions of the layer of material (510).
