Abstract

A multichip semiconductor device is disclosed in which chips are stacked each of which comprises a semiconductor substrate formed on top with circuit components and an interlayer insulating film formed on the top of the semiconductor substrate. At least one of the chips has a connect plug of a metal formed in a through hole that passes through the semiconductor substrate and the interlayer insulating film. The chip with the connect plug is electrically connected with another chip by that connect plug.
