Alignment mark design for semiconductor device
Abstract:
Better alignment mark designs for semiconductor devices may substantially lessen the frequency of layer misalignment scanner alignment problems. Exemplary alignment mark designs substantially avoid or minimize damage during the fill-in and etching and chemical mechanical processing processes. Thus, additional processing steps to even out various layers or to address the misalignment problems may also be avoided.
