Tape automated bonding(tab)semiconductor device and method for making the same

摘要

Deformation of TAB tapes due to temperature changes is prevented by thermo-mechanical leads. In one embodiment of the invention, a semiconductor device (30) includes an electronic component (31) and a TAB tape. The tape includes a carrier film (12) and electrical leads (20) formed on the carrier film. The electrical leads are electrically coupled to the electronic component. Also included on the carrier film are thermo-mechanical leads (32) which are formed in opposing regions of the carrier film, regions which are typically void of leads. The thermo-mechanical leads have approximately the same lead pitch as the electrical leads in order to provide a uniform distribution of stresses across the TAB tape upon exposure to varying temperatures.
