Abstract

A method of production of a multilayer circuit board comprised of a multilayer structure circuit formed by a plurality of interconnect layers and insulation layers stacked together and a semiconductor chip included therein, including the steps of placing a semiconductor chip having a polished back surface, with its active surface facing downward, on an already formed lower interconnect layer and forming an insulation layer over the layer on which the semiconductor chip has been placed, the method further including the step of treating the polished back surface of the semiconductor chip to improve its bondability with the insulation layer before the step for formation of the insulation layer.
