摘要
A semiconductor chip assembly includes a semiconductor device, a heat spreader, a conductive trace and an adhesive. The semiconductor device is electrically connected to the conductive trace and thermally connected to the heat spreader. The heat spreader is aluminum and includes a post and a base. The post extends upwardly from the base into an opening in the adhesive, and the base extends laterally from the post. The adhesive extends between the post and the conductive trace and between the base and the conductive trace. The conductive trace includes a silver coating and a copper core and provides signal routing between a pad and a terminal.
