Patent ID: 7643311

Claim:
An electronic circuit device, comprising: a support; first and second circuit portions including first and second integrated circuit chips, respectively, the first and second circuit portions being covered respectively with first and second insulating blocks; first and second metal cages respectively covering the first and second insulating blocks; and first and second conductive strip patterns formed on a first surface of the support and completely laterally surrounding the first and second circuit portions, respectively, the first and second metal cages being electrically connected to the first and second conductive strip patterns and being connected to the support via the conductive strip patterns, wherein the first and second insulating blocks are separated from each other by a recess, the first metal cage having a first wall positioned along a first side of the recess, the second metal cage having a second wall positioned along a second side of the recess, and the first and second conductive strip patterns sharing a common conductive strip positioned along a third side of the recess, the first and second walls being separated from one another and being electrically connected to each other and to the common conductive strip.
