Abstract:
1. A circuit device having top, side, and bottom surfaces, the circuit device comprising: conductive patterns separated by isolation trenches, each conductive pattern comprising a respective upper surface facing the top surface of the circuit device and a respective lower surface facing the bottom surface of the circuit device; circuit elements comprising terminals electrically connected to the conductive patterns; and a sealing resin covering the conductive patterns, the circuit elements, the upper surface and the side surfaces and not covering back sides of the conductive patterns, wherein the sealing resin disposed in the isolation trenches projects downward from the lower surface of the conductive patterns; wherein the conductive patterns are equally separated by the isolation trenches and wherein the circuit device is hexahedral and all surfaces except for the bottom surface comprise the sealing resin.
