  • Patent number: 7141507
    Abstract: A method for producing a semiconductor structure including preparing a semiconductor substrate, and generating a lower first, a middle second and an upper third masking layer on a surface of the semiconductor substrate. The method further includes forming at least one first window in the upper third masking layer, structuring the middle second masking layer using the first window for transferring the first window, structuring the lower first masking layer using the first window for transferring the first window, and enlarging the first window to form a second window. The method for further includes restructuring the middle second masking layer using the second window for transferring the second window, structuring the semiconductor substrate, using the structured lower third masking layer, restructuring the lower first masking layer using the second window, and restructuring the semiconductor substrate using the restructured lower third masking layer.

  • Patent number: 7049228
    Abstract: A process for introducing structures that have different dimensions, particularly with regard to depth, in which just one lithography level is required, is disclosed. This is achieved by use of a layer stack deposited on a substrate, where one layer in particular is used to store information related to the dimensioning of the different structures. The layer is partially opened up to expose the substrate at locations corresponding to where deep structures are to be formed. Deep structures are subsequently etched into the substrate, after which the layer is opened up at locations corresponding to where shallow structures are to be formed. The latter locations are subsequently etched to the desired depth of the shallower structures. The process can be used instead of conventional the dual damascene technology for the structuring of contact holes and interconnects.

  • Patent number: 6809800
    Abstract: An apparatus (100) for patterning the surface of a semiconductor wafer (130). A stage (148) is coupled to a motor (150) that is adapted to move the stage (148) and a semiconductor wafer (130) in a horizontal direction at a first speed A. A mask (140) is disposed above the semiconductor wafer (130), the mask (140) being coupled to a motor (142) that is adapted to move the mask (140) in a horizontal direction at a second speed B. The ratio of the first and second speeds is different than the magnification factor, which may be other than 1:1 if a lens (120) is used. The mask (140) and the wafer (130) may be moved in the same horizontal direction simultaneously during the exposure process at different speeds B and A, respectively, to provide a magnification or demagnification of the mask (140) pattern onto the wafer (130) surface.

  • Patent number: 6740594
    Abstract: A method for removing a carbon-containing polysilane from a semiconductor substrate without stripping the polysilane during manufacture of a semiconductor device, the method entailing the steps in the following order of coating a carbon-containing polysilane on a semiconductor substrate and coating a resist on the polysilane; patterning the resist with exposure and development; transferring the pattern from the resist to the polysilane using an etch process selective to the resist; stripping the resist; transferring the pattern from the polysilane to a hardmask using an etch selective to the hardmask; subjecting the polysilane to thermal or plasma/thermal oxidation to convert the polysilane to silicon oxide; and etching the substrate and stripping off the hardmask.
