摘要： 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.

摘要： A layer of a semiconductor material is epitaxially grown on a single-crystal semiconductor structure and on a polycrystalline semiconductor structure. The epitaxial layer is then etched in order to preserve a non-zero thickness of said material on the single-crystal structure and a zero thickness on the polycrystalline structure. The process of growth and etch is repeated, with the same material or with a different material in each repetition, until a stack of epitaxial layers on said single-crystal structure has reached a desired thickness. The single crystal structure is preferably a source/drain region of a transistor, and the polycrystalline structure is preferably a gate of that transistor.

摘要： A method is provided for fabricating transistors of first and second types in a single substrate. First and second active zones of the substrate are delimited by lateral isolation trench regions, and a portion of the second active zone is removed so that the second active zone is below the first active zone. First and second layers of semiconductor material are formed on the second active zone, so that the second layer is substantially in the same plane as the first active zone. Insulated gates are produced on the first active zone and the second layer. At least one isolation trench region is selectively removed, and the first layer is selectively removed so as to form a tunnel under the second layer. The tunnel is filled with a dielectric material to insulate the second layer from the second active zone of the substrate. Also provided is such an integrated circuit.
