Abstract

A chip structure is provided. The chip structure includes a semiconductor substrate. The chip structure includes a first dielectric layer over the semiconductor substrate. The chip structure includes a first conductive layer over the first dielectric layer. The chip structure includes a second dielectric layer over the first conductive layer and the first dielectric layer. The chip structure includes a first conductive via passing through the second dielectric layer, the first conductive layer, and the first dielectric layer and electrically connected to the first conductive layer. The chip structure includes a second conductive via passing through the second dielectric layer and the first dielectric layer. The chip structure includes a first conductive pad over and in direct contact with the first conductive via. The chip structure includes a second conductive pad over and in direct contact with the second conductive via.
