  • Publication number: 20100040983
    Abstract: A method of manufacturing integrated circuits includes determining a process-induced displacement (e.g., a stress-induced displacement) between primary structures on a substrate and providing a photomask with mask features assigned to the primary structures. The distances between the mask features are set such that the process-induced displacement is compensated.

  • Patent number: 6586308
    Abstract: A method for producing circuit structures on a semiconductor substrate is described. Photoresist structures are formed, which define functional circuit structures and dummy circuit structures, whereby the dummy circuit structures which are smaller than a minimum structural size are joined to an additional second dummy circuit structure. The additional circuit structure is provided in such a way that the minimum structural size, which is determined by a smallest required joint surface of the photoresist on the substrate, is exceeded. A semiconductor circuit is also provided, which includes functional circuit structures and dummy circuit structures, the dummy circuit structures being joined to the additional dummy circuit structures.

  • Patent number: 6086269
    Abstract: A method and an apparatus apply a substance, especially a developer, to a surface through jets. Each jet carries the substance to be applied to a predetermined portion of the surface, and each jet essentially applies a predetermined quantity of substance per unit of surface area, wherein at least one jet applies a maximum quantity of substance per unit of surface area to the surface. The quantity of substance per unit of surface area applied by each jet is selected in such a way that it is greater than 1% of the maximum quantity of substance per unit of surface area.
