  • Publication number: 20090269914
    Abstract: Process for forming a dielectric. The process may include forming the dielectric on a metallization and capacitor arrangement. The process allows the direct application of a dielectric layer to a copper-containing metallization. Accordingly, two process gases may be excited with different plasma powers per unit substrate area, or one process gas may be excited with a plasma and another process gas may not be excited.

  • Patent number: 7342292
    Abstract: A capacitor assembly has a substrate, a first conductive auxiliary layer on the substrate, a capacitor dielectric, a second conductive auxiliary layer and a contact electrode. Thereby the first conductive auxiliary layer is connected to the capacitor dielectric within a first boundary area and the second conductive auxiliary layer is connected to the capacitor dielectric within a second boundary area. Thereby, an effective capacitor area is present where the first boundary area and the second boundary area overlap across the capacitor dielectric. The contact electrode is connected to the first conductive auxiliary layer in a contacting area, wherein the contacting area is disposed on a surface of the first conductive auxiliary layer opposite to the first boundary area and overlaps the effective capacitor area partly or not at all, so that at least part of the first conductive auxiliary layer within the effective capacitor area is adjacent to the substrate or not to the contact electrode.

  • Patent number: 7233053
    Abstract: To fabricate an integrated semiconductor product with integrated metal-insulator-metal capacitor, first of all a dielectric auxiliary layer (6) is deposited on a first electrode (2, 3, 5). This auxiliary layer (6) is then opened up (15) via the first electrode. Then, a dielectric layer (7) is produced, and the metal track stack (8, 9, 10) for the second electrode is then applied to the dielectric layer (6). This is followed by the patterning of the metal-insulator-metal capacitor using known etching processes. This makes it possible to produce dielectric capacitor layers of any desired thickness using materials which can be selected as desired. In particular, this has the advantage that via etches can be carried out significantly more easily than in the prior art, since it is not necessary to etch through the residual dielectric capacitor layer above the metal tracks.
