Abstract

The invention can obtain a semiconductor device that can be easily produced and can reduce the chip area. The semiconductor chip has a top surface, a bottom surface and a lateral surface connecting the top surface and the bottom surface. Bottom surface electrodes are formed on the bottom surface of the semiconductor chip. Lateral surface wiring is formed on the lateral surface of the corner of the semiconductor chip. The lateral surface wiring is connected to the electronic circuit and the bottom surface electrodes.

Description

technical field [0001] The present invention relates to a semiconductor device in which side wiring is formed on a side surface of a semiconductor chip, and more particularly to a semiconductor device which can be easily manufactured and has a reduced chip area. Background technique [0002] In a semiconductor device in which a semiconductor chip is mounted on a mounting portion, wire bonding, flip chip, side wiring, etc. are used to connect an electronic circuit of the semiconductor chip to electrodes of the mounting portion. Side wiring is formed on the side surface of the semiconductor chip by cutting through holes provided on dicing lines of the semiconductor wafer (for example, refer to Patent Document 1: Japanese Patent Application Laid-Open No. 6-120294). [0003] Conventionally, side wiring is formed on the side of a semiconductor chip. Therefore, side wirings of two semiconductor chips are formed by one through hole. Therefore, many through holes must be formed in...
