Abstract: A test pattern structure including a first conductive layer and a second conductive layer is provided. The second conductive layer is directly disposed on the first conductive layer and connected to the first conductive layer through a plurality of connection interfaces. The test pattern structure of the present invention can detect the interconnection failure quickly and correctly without SEM identification.
