发明名称 Alignment mark design for semiconductor device
摘要 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.
