Abstract

A capacitance circuit for measuring the coverage error mainly comprises the first structure, the second structure and the third structure; the said first structure is the first conducting layer structure, which has at least one pair of sensing arms; the said second structure is formed on the said first structure, the said second structure is an insulation structure which covers the said first structure completely; the said third structure is formed on the second structure, which is a second conducting layer structure having the first main body and at least one pair of second sensing arms corresponding to the first sensing arm. The present invention is suitable to be used in measuring the coverage error of conducting layers with an insulation layer in between.
