Patent ID: 6894373

Claim:
An electronic circuit unit comprising: an alumina substrate; thin film circuit elements including at least one capacitor, at least one resistor, and at least one inductance element formed on one surface of the alumina substrate; an upper conductive pattern and lower conductive pattern formed on the one surface and an opposing surface of the alumina substrate, respectively, the upper and lower conductive patterns being thin films; at least one semiconductor chip wire bonded to the upper conductive pattern; a thermosetting resin that seals the circuit elements, upper conductive pattern, and semiconductor chip on the alumina substrate; and an edge electrode sputtered on a side surface of the alumina substrate, wherein an edge of the upper conductive pattern is exposed from a side surface of the thermosetting resin, and the edge electrode provides a connection between respective edges of the upper conductive pattern and the lower conductive pattern, and ground electrodes are disposed near corners on a first side of the one surface and on a second side opposing the first side with non-ground electrodes disposed between the ground electrodes, and on the second side a ground electrode is disposed adjacent to one of the other two ground electrodes.
