Abstract

A leadframe of a semiconductor device includes a die pad, first and second suspension leads, and a frame. The main surfaces of the die pad and the frame are located on different planes, and the die pad and the frame are connected to each other by the first and second suspension leads. A first boundary line between the first suspension lead and the die pad runs on a straight line different from a second boundary line between the second suspension lead and the die pad. A third boundary line between the first suspension lead and the frame runs on a straight line different from a fourth boundary line between the second suspension lead and the frame.
