Patent ID: 7943433

Claim:
A method of manufacturing a semiconductor device comprising: a semiconductor chip including a quadrilateral main surface having first and second vertices on a diagonal line and first and second sides connecting said first and second vertices, and including a group of pads on said main surface; a group of electrodes; a group of wires connecting said group of pads and said group of electrodes; and a resin portion encapsulating said group of wires, said method comprising the steps of: forming said group of wires between said group of pads and said group of electrodes, said step of forming said group of wires including forming a first wire of said group of wires between a first pad of said group of pads and a first electrode of said group of electrodes; enclosing said group of wires in a cavity of a mold; pouring a liquid resin into said cavity such that said liquid resin flows from said first vertex toward said second vertex along said first and second sides; and forming said resin portion by curing said liquid resin, said first wire being formed such that said first wire crosses said second side of said main surface and has a portion bent toward said second vertex relative to a straight line connecting said first pad and said first electrode as seen in a plan view, wherein said step of forming said group of wires includes forming a second wire of said group of wires between a second pad of said group of pads and a second electrode of said group of electrodes, and said second wire is formed such that the entire second wire extends on a straight line connecting said second pad and said second electrode as seen in the plan view.
