Abstract
A structure includes an insulating layer on a semiconductor substrate, and a first through-hole and a second through-hole formed in the insulating layer. The second through-hole is formed in the insulating layer at a set distance from the first through-hole. The structure also includes a first electrode portion and a second electrode portion. The first electrode portion is formed by filling the first through-hole. The first electrode portion includes a probing pad on the insulating layer. The probing pad is wider than an opening area of the first through-hole. The second electrode portion is formed by filling the second through-hole. The second electrode portion includes a probing pad on the insulating layer. The probing pad is wider than an opening area of the second through-hole.
