Problems solved by technology

[0006] Flip-chip connection can achieve faster signal transmission between semiconductor elements and wiring boards than wire bonding connections, but as the number of pads on semiconductor elements increases and the pitch becomes narrower, the connection strength of solder bumps weakens, so There are many defects such as cracks in the connection part

Abstract

Provided is a higher density, thinner and lower cost semiconductor device by eliminating reliability failure due to concentration of internal stress in a final semiconductor device. The semiconductor device is provided with a semiconductor element; a supporting substrate, which is arranged on a surface opposite to a surface whereupon a pad of the semiconductor element is arranged, and has an area larger than that of the semiconductor element; an embedding insulating layer for embedding the semiconductor element on the supporting substrate; a fan-out wiring lead out from the pad to a region on the outer circumference side of the semiconductor element on the embedding insulating layer; and a wiring thickness reinforcing section, which is arranged in a prescribed region above the outer circumference section of the semiconductor element for reinforcing mechanical strength of the embedding insulating layer and the fan-out wiring.

Description

technical field [0001] Description of the relevant application [0002] The present invention is based on and claims priority to the prior Japanese Patent Application No. 2007-273929 (filed on October 22, 2007), and the entire content of the prior application is described in this specification by reference. [0003] The present invention relates to a semiconductor device incorporating a semiconductor element. Background technique [0004] With the continuous miniaturization of electronic equipment, the miniaturization and integration of semiconductor elements themselves, as well as the high-density mounting technology in semiconductor packages, are progressing day by day. Conventionally, in the packaging of semiconductor elements, there are wire bonding connections using gold wires or the like and flip chip connections using solder balls or the like as methods of connecting the wiring board of the package and the semiconductor elements. [0005] Although the wire bonding c...
