Abstract
A pressure sensor device is assembled by forming cavities on a surface of a metal sheet and then forming an electrically conductive pattern having traces and bumps over the cavities. An insulating layer is formed on top of the pattern and then processed to form exposed areas and die attach areas on the surface of the metal sheet. The exposed areas are plated with a conductive metal and then electrically connected to respective ones of the bumps. A gel is dispensed on the die attach areas and sensor dies are attached to respective die attach areas. One or more additional semiconductor dies are attached to the insulating layer and bond pads of these dies are electrically connected to the exposed plated areas. A molding compound is dispensed such that it covers the sensor die and the additional dies. The metal sheet is removed to expose outer surfaces of the bumps.
