Abstract:
1. A semiconductor device comprising: a first insulating layer formed over a substrate; a first conductive layer formed over the first insulating layer; a second insulating layer formed over the first conductive layer; a second conductive layer formed over the second insulating layer and having a first overlapping portion that overlaps the first conductive layer at a first position; a third insulating layer formed over the second conductive layer; a third conductive layer formed over the third insulating layer, the third conductive layer having a second overlapping portion that overlaps the second conductive layer at a second position different from the first position and having a third overlapping portion that overlaps the first conductive layer and the second conductive layer at a third position different from the first and second positions; and a contact hole formed in at least one of the first overlapping portion and the second overlapping portion and electrically connecting two out of said first, second, and third conductive layers to each other.
