An inexpensive pre-molded package for electronic semiconductor circuit with increased thermal extraction capability, improved electrical performance, improved dielectric constant of sealing medium, optically transmissive sealing lid, and partially reduced electromagnetic radiation. In one embodiment, the pre-molded package includes electronic semiconductor circuit, a plurality of electrically conductive leads, a heat spreader, a plurality of electrically conductive bond wires, and a seal lid. Preferably, a surface of the heat spreader remains exposed to the exterior of the pre-molded package. In another embodiment, the pre-molded package includes a semiconductor circuit, a plurality of electrically conductive leads, a heat spreader, a plurality of electrically conductive bond wires, and an optically transmissive seal lid.
