Abstract
In the present invention, a first circuit patterncomposing a semiconductor element is formed on the front side of a substrate, a first insulating layeris formed on the first circuit pattern, solder electrodesfor external connection are formed on the first insulating layer, a second insulating layeris formed on the backside of the substrate, a second circuit patternis formed on the second insulating layer, through viasare formed to connect the first circuit patternand the second circuit pattern, chip passive componentsare placed on the second circuit pattern, and the backside of the substrate is integrally molded with epoxy resinsuch that the epoxy resincovers the chip passive components
