Semiconductor device and semiconductor device manufacturing method

Abstract

In a semiconductor device including a semiconductor wafer having a main surface where a circuit element is formed, electrode pads are formed at an upper portion of the main surface of the semiconductor wafer as electrically connected with the circuit element. A sealing resin seals the upper portion of the main surface of the semiconductor wafer, and external connection terminals are formed at the upper portion of the main surface so as to project out from the surface of the sealing resin and are arrayed in a substantially regular pattern over specific intervals from one another. At least one of the external connection terminals has a shape different from the shape of the other external connection terminals. The shape of the external connection terminal is used as an index mark, so that the index mark forming process is simplified and the index mark does not come off.
