发明名称 Apparatus and method for enhanced thermal conductivity packages for high powered semiconductor devices
摘要 An apparatus and method for an enhanced thermally conductive package for high powered semiconductor devices. The package includes a semiconductor die having an active surface and a non-active surface and a metal layer formed on the non-active surface of the die. The package is intended to be mounted onto a metal pad provided on a printed circuit board. A solder is used to affix the metal layer on the non-active surface of the die to the metal pad of the printed circuit board. The interface between the die and the printed circuit board thus includes just three metal layers, including the non-active surface of the die, the solder, and the metal pad on the printed circuit board. The reduced number of metal layers improves heat dissipation and thermal conductivity of the package.
