  • Publication number: 20070069327
    Abstract: In a method for manufacturing an integrated semiconductor device with low capacitive coupling between a conductive member and a via, a semiconductor substrate with a surface is provided. The conductive member is formed on the surface of the substrate wherein the conductive member is provided for conducting a current in a direction parallel to the surface of the substrate. A sacrifice structure is produced. A via is formed for conducting a current in a direction vertical to the surface of the substrate. The sacrifice structure at least partially defines the shape and position of the via and separates the conductive member and the via. The sacrifice structure is removed thereby generating a void in place of the sacrifice structure.

  • Patent number: 6764954
    Abstract: The invention relates to a method for applying adjusting marks on a semiconductor disk. A small part structure consisting a non-metal is produced in an extensive metal layer and the semiconductor disk is subsequently planed in said region with the help of chemical and mechanical polishing. The structural sizes in the metal layer and the chemical-mechanical polishing process are adjusted to each other, in such a way that the small part non-metal structure protrudes above the extensive metal layer after polishing.
