Abstract

A robust, low inductance electronic package for small area semiconductor chips is provided which includes a flexible polymer film having electronic circuitry on one or more major surfaces, a bumped flip chip integrated circuit attached to the first surface, an array of solder balls to the second surface, and the device encapsulated in a plastic molding compound. An assembly and packaging method is disclosed wherein multiple devices are encapsulated simultaneously on a continuous polymer film, thereby providing a method compatible with high volume and low cost manufacturing processes and equipment.
