Abstract

A semiconductor mounting structure is provided with: a semiconductor having first electrodes,a circuit board having second electrodes,bumps formed on the first electrodes,bonding members, which are arranged between the bumps and the second electrodes and electrically connect together the first electrodes and the second electrodes with the bumps therebetween,and reinforcing resin members arranged at the periphery of each bonding member so as to cover at least bonding portions between the bumps and the bonding members and the bonding members. The reinforcing resin members are arranged by being spaced apart from each other such that the adjacent reinforcing resin members are not in contact with each other and with the semiconductor. Thus, in the semiconductor mounting structure, impact resistance reliability of connecting sections is improved, and the semiconductor mounting structure can be easily repaired.

Description

technical field [0001] The present invention relates to a semiconductor mounting structure in which semiconductors such as a semiconductor chip (semiconductor element) and a semiconductor package are electrically connected to a circuit board, and a method for manufacturing the same. Background technique [0002] Mobile devices such as mobile phones and PDAs (Personal Digital Assistants) are becoming smaller and more functional, and mounting structures such as BGA (Ball Grid Array) and CSP (Chip Scale Package) are widely used as mounting technologies that can cope with this. . Mobile equipment is susceptible to mechanical loads such as drop shocks. Therefore, for mounting structures such as BGAs and CSPs that do not have shock-mitigating mechanisms, such as lead wires of a QFP (Quad Flat Package), it is important to secure shock-resistant reliability of the solder connection. [0003] Therefore, for example, when connecting a BGA type semiconductor package and an electronic...
