Patent ID: 7838998

Claim:
A semiconductor device comprising: a mounting substrate; and a semiconductor chip mounted on the mounting substrate in a flip chip manner, wherein the mounting substrate has a plurality of connection pads to which the semiconductor chip is connected, an insulating pattern formed of a solder resist material so as to cover a part of the connection pads, and a plurality of dummy patterns formed of a solder resist material for controlling a flow of an underfill infiltrated between the semiconductor chip and the mounting substrate, and wherein the plurality of connection pads include: first connection pads connected to a peripheral edge of the semiconductor chip; and at least one second connection pad connected to the semiconductor chip at a position that is spaced from the peripheral edge of the semiconductor chip such that the at least one second connection pad is surrounded by the first connection pads, wherein the dummy patterns are arranged in lattice shape surrounding the at least one second connection pad and forming a flow path that directs the underfill to surround the at least one second connection pad, and the dummy patterns are surrounded by the first connection pads.
