Abstract
There is provided an electronic package where the package components define a cavity. A semiconductor device and a portion of a leadframe occupy part of the cavity. Substantially the remainder of the cavity is filled with a compliant polymer, such as a silicone gel. Since the cavity is no longer susceptible to gross leak failure, the seal width of adhesives used to assemble the package may be reduced, thereby increasing the area available for mounting the semiconductor device.
