    Abstract: The circuit includes a first semiconductor substrate supporting the electronic circuit, and a second substrate carrying an electromechanical component. The two substrates are glued together forming a sealed and protective enclosure for the auxiliary component. The first phase of manufacture includes forming the semiconductor chip (PC) within a first substrate, and forming a cavity in the upper surface of this substrate to accommodate an auxiliary component. A wall remains around the cavity, leaving the cavity as a well. The second phase includes formation of the auxiliary component (CAX) on a second semiconductor substrate (SB2), separate from the first. The second substrate is then turned over and applied to the first substrate as a lid with the auxiliary component hanging within the cavity of the first substrate. The two substrates are glued together forming a sealed and protective enclosure for the auxiliary component.

    Abstract: Metal contacts are self-positioned on a wafer of semiconductor product. Respective placement areas for a metal contact are determined by a selective deposition of a growth material over a region of the substrate surface (for example, through epitaxial growth). The growth material is surrounded by an insulating material. The grown material is then removed to form a void in the insulating material which coincides with the desired location of the metal contact. This removal of the grown material exposes the region on the substrate surface. Conductive material is then deposited to fill the void and thus form the metal contact directly with the region of the substrate surface.
