Abstract:
A method for manufacturing the semiconductor apparatus includes an anchor process of forming a barrier metal film and carrying out physical etching making use of sputter gas. The anchor process is carried out at the same time on a wire connected to the lower portion of a first aperture serving as a penetration connection hole and a wire connected to the lower portion of a second aperture serving as a connection hole having an aspect ratio different from the aspect ratio of the penetration connection hole. The first and second apertures are apertures created on a semiconductor substrate obtained by bonding first and second semiconductor substrates to each other. The present technology can be applied to the semiconductor apparatus such as a solid-state imaging apparatus.
