Abstract:
A semiconductor device and a method for manufacturing the device include connecting a second wafer to a first wafer, forming a hard mask layer on and/or over a backside of the second wafer, forming a hard mask pattern over the second layer and then forming a via hole by etching the first and the second wafers to a predetermined depth using the hard mask pattern as an etching mask.
