    Abstract: The production of a semiconductor wafer useful in e.g. chip cards, comprises providing a semiconductor substrate (1) from a first semiconductor material with a first surface and a second surface, which faces the first surface, applying a first semiconductor layer (2) from a second semiconductor material epitaxially on the second surface, and partially removing the substrate from the first semiconductor layer. The epitaxial application of a second semiconductor layer (3) from a third semiconductor material on the first semiconductor layer takes place to the desired target thickness. The production of a semiconductor wafer useful in e.g. chip cards, comprises providing a semiconductor substrate (1) from a first semiconductor material with a first surface and a second surface, which faces the first surface, applying a first semiconductor layer (2) from a second semiconductor material epitaxially on the second surface, and partially removing the substrate from the first semiconductor layer. The epitaxial application of a second semiconductor layer (3) from a third semiconductor material on the first semiconductor layer takes place to the desired target thickness. After the partial removing, the first semiconductor layer is partly removed via corroding. Before corroding a prefabricated device is attached as an etching mask at the first surface of the substrate. The device covers an external area of the first surface and limits an opening that releases an internal area of the first surface of the substrate, and is again removed after corroding. A semiconductor component (4) is formed in the first- and second semiconductor layer before the partial removing of the substrate.

    Abstract: A damascene method of forming conductive lines in an integrated circuit chip. Trenches are etched by a plasma formed by capacitively coupling a gas mixture at 500 to 3000watts under a pressure of 50 - 400mTorr. The gas mixture includes 2 - 30sccm of C4F8, 20 - 80sccm of CO, 2 - 30sccm of O2 and 50 - 400sccm of Ar. Gas flow can be adjusted to an optimum level, thereby achieving a high degree of uniformity. Wafers falling below a selected uniformity may be reworked. A damascene wiring layer formed in the trenches with an acceptable flow exhibit a high degree of sheet resistance uniformity and improved line to line shorts yield.
