Abstract
A semiconductor device in which a semiconductor has good heat dissipation efficiency, a display employing such a semiconductor device and a method for manufacturing a semiconductor device. A conductive pattern providing a semiconductor-connecting terminal portion and further providing first and second external-connection terminal portion on the opposite sides of the semiconductor-connecting terminal portion is formed on the surface of a flexible insulating substrate to produce a flexible printed wiring board on which a semiconductor is mounted and connected with the semiconductor-connecting terminal portion in the conductive pattern. In such a semiconductor device, a slit is formed in the insulating substrate to surround the semiconductor while leaving a part around the semiconductor thus providing a semiconductor holding part. The insulating substrate is turned down such that the surface comes inside excepting the semiconductor holding part, and the slit is formed such that the mounted semiconductor projects from the backside of the insulating substrate to the outside when the first and second external-connection terminal portion are connected, respectively, with other components.
