    摘要: A mark structure for measuring the alignment accuracy between a former layer and a latter layer with electron beam inspection (EBI) is described. The mark structure includes multiple divisions, each of which includes at least one region that includes multiple parts each disposed with a pair of a pattern of the former layer and a pattern of the latter layer. In each region, all of the parts have the same distance in a direction between the pattern of the former layer and the pattern of the latter layer. The distance in the direction is varied over the regions of the divisions of the mark structure.

    摘要: The present invention relates to a fabricating method of a semiconductor element. First, a substrate is provided and a first layout structure having a first width is formed on the substrate. Then, an etching mask is formed to cover the first layout structure, and the etching mask exposes a portion of the first layout structure. After that, the first layout structure is etched with the etching mask to form a second layout structure having a second width. The second width is less than the first width. This fabricating method is capable of finishing the fabrication of gate structures in two different directions. Accordingly, the layout flexibility is improved.
