Abstract:
A semiconductor device comprising:a plurality of leads, each of said leads having an elongated chip mounting portion electrically connected to a semiconductor chip, through a bump, and a lead main body;said lead main body supporting said chip mounting portion,wherein a lead path from a distal end of said lead main body to said bump is bent in X, Y, and Z directions forming a step shape projecting upward so that said distal end portion of said lead main body is at a lower level than said elongated chip mounting portion when viewed from a side surface of said device, and each lead main body and each elongated chip mounting portion substantially make a right angle to form a L-shaped lead as when viewed from an upper surface of said device;said semiconductor chip connected, through bumps, to upper surfaces of distal end portions of said elongated chip mounting portions of said leads which are arranged on a plane;a molded body sealing constituent elements except a portion of each said distal end of each said lead main body,wherein each of said plurality of leads is arranged such that said elongated chip mounting portions are arranged on both sides of a centerline of said semiconductor device in a longitudinal direction to be parallel to said centerline, andsaid L-shaped leads are arranged on one side such that said chip mounting portions oppose each other on a plane.
