Abstract: Eine erste metallische Hartmaskenschicht über einer dielektrischen Zwischenverbindungsebenen-Schicht wird mit einem Leitungsmuster strukturiert. Oberhalb der ersten metallischen Hartmaskenschicht wird wenigstens eine Schicht aus einem dielektrischen Material, eine zweite metallische Hartmaskenschicht, eine erste organische Planarisierungsschicht (OPL) sowie ein erstes Photoresist angebracht. Ein erstes Durchkontakt-Muster wird von der ersten Photoresistschicht in die zweite metallische Hartmaskenschicht hinein transferiert. Eine zweite OPL und ein zweites Photoresist werden angebracht und mit einem zweiten Durchkontakt-Muster strukturiert, das in die zweite metallische Hartmaskenschicht hinein transferiert wird. Ein erstes Kombinationsmuster aus dem ersten und dem zweiten Durchkontaktmuster wird in die wenigstens eine Schicht aus einem dielektrischen Material transferiert. Ein zweites Kombinationsmuster, welches das erste Kombinationsmuster mit den Gebieten der Öffnungen in der ersten metallischen Hartmaskenschicht begrenzt, wird in die dielektrische Zwischenverbindungsebenen-Schicht hinein transferiert.

Abstract: Embodiments of the present invention provide a structure. The structure includes a plurality of field-effect-transistors having gate stacks formed on top of a semiconductor substrate, the gate stacks having spacers formed at sidewalls thereof; and one or more conductive contacts formed directly on top of the semiconductor substrate and interconnecting at least one source/drain of one of the plurality of field-effect-transistors to at least one source/drain of another one of the plurality of field-effect- transistors, wherein the one or more conductive contacts is part of a low-profile local interconnect that has a height lower than a height of the gate stacks.

Abstract: THE PRESENT INVENTION PROVIDES A METHOD FOR FORMING SELF-ALIGNED SPACERS (502) ON THE HORIZONTAL SURFACES WHILE REMOVING SPACER MATERIAL FROM THE VERTICAL SURFACES. THE PREFERRED METHOD USES A RESIST(302) THAT CAN BE MADE INSOLUBLE TO DEVELOPER BY THE USE OF AN IMPLANT. BY CONFORMALLY DEPOSITING THE RESIST OVER A SUBSTRATE (202) HAVING BOTH VERTICAL AND HORIZONTAL SURFACES, IMPLANTING THE RESIST, AND DEVELOPING THE RESIST, THE RESIST IS REMOVED FROM THE VERTICAL SURFACES WHILE REMAINING ON THE HORIZONTAL SURFACES. THUS, A SELF-ALIGNED SPACER IS FORMED ON THE HORIZONTAL SURFACES WHILE THE SPACER MATERIAL IS REMOVED FROM THE VERTICAL SURFACES. THIS HORIZONTAL-SURFACE SPACER CAN THEN BE USED IN FURTHER FABRICATION. THE PREFERRED METHOD CAN BEUSED IN MANY DIFFERENT PROCESSES WHERE THERE IS EXISTS A NEED TO DIFFERENTIALLY PROCESS THE VERTICAL AND HORIZONTAL SURFACES OF A SUBSTRATE.FIG. 1

Abstract: Disclosed is a process for forming a film comprising a polysilane composition on a substrate. The film is formed by vapor deposition directly on a substrate, thus avoiding the cumbersome steps ordinarily encountered in preparing and applying polysilanes by conventional spin application techniques. The film is used in a lithographic process for forming an image on a substrate.

Abstract: A first metallic hard mask layer over an interconnect-level dielectric layer is patterned with a line pattern. At least one dielectric material layer, a second metallic hard mask layer, a first organic planarization layer (OPL), and a first photoresist are applied above the first metallic hard mask layer. A first via pattern is transferred from the first photoresist layer into the second metallic hard mask layer. A second OPL and a second photoresist are applied and patterned with a second via pattern, which is transferred into the second metallic hard mask layer. A first composite pattern of the first and second via patterns is transferred into the at least one dielectric material layer. A second composite pattern that limits the first composite pattern with the areas of the openings in the first metallic hard mask layer is transferred into the interconnect-level dielectric layer.
