Abstract:
A method for producing a semiconductor device comprising:producing a plurality of monolithic electronic components on a semiconductor substrate, a first insulator layer covering said semiconductor substrate, a plurality of contact pads arranged on said first insulator layer and connected to electrodes of said monolithic electronic components, a second insulator layer covering said plurality of contact pads, and a plurality of plug-shaped conductive pieces penetrating said second insulator layer and being connected with said contact pads;producing a layer of a material which is conductive and accepts an etching process on said second insulator layer and a conductive layer produced on said layer of a material which is conductive and accepts an etching process;producing an etching mask in accordance with a design criteria of the semiconductor device, the design criteria specifying selected ones of said plug-shaped conductive pieces, said etching mask being produced such that a horizontal width of the etching mask is larger at locations corresponding to the selected ones of said plug-shaped conductive pieces than at locations corresponding to the unselected ones of said plug-shaped conductive pieces;using said etching mask to etch the conductive layer and the layer of a material which is conductive and accepts an etching process to connect an interconnection layer with only said selected ones of said plug-shaped conductive pieces.
