Abstract
An integrated circuit package where the integrated circuit chip is mounted on a conductive slug and electrically coupled to the slug. Besides acting as a heat spreader, the conductive slug may also function as a ground plane. This reduces the need for additional conductive layers and plated through hole connections for forming connections to, for example, ground. As a result, the conductive paths in the internal ground planes are not necessarily cut off by the plated through holes used for interconnecting ground connections thus avoiding some of the electrical performance degradation suffered by prior techniques. In addition, the invention allows more signals to be added and/or the size of the integrated circuit chip to be reduced to enhance electrical performance. It is to be understood that both the foregoing general description and the following detailed description are exemplary, but are not restrictive, of the invention.
