description The disclosure provides a method for manufacturing a semiconductor device. The method, in one embodiment, includes forming semiconductor features over a substrate, and then forming a layer of material over the semiconductor features. This method further includes selectively etching portions of the layer of material based upon a density or size of the semiconductor features located thereunder, and then polishing remaining portions of the layer of material.
