  • Patent number: 8664025
    Abstract: The width of scribe lines may be reduced in semiconductor devices by applying a process technique in which trenches may be formed first from the rear side on the basis of a required width of the corresponding trenches, while subsequently it may be cut into the substrate from the front side on the basis of a reduced thickness of the corresponding saw blades, thereby also enabling a reduction of the scribe line width. Furthermore, contamination of the front side, i.e., of the metallization system, may be reduced, for instance, by performing an optional intermediate cleaning process.

  • Patent number: 8658509
    Abstract: In sophisticated semiconductor devices comprising high-k metal gate electrode structures formed on the basis of a replacement gate approach, semiconductor-based resistors may be provided without contributing to undue process complexity in that the resistor region is recessed prior to depositing the semiconductor material of the gate electrode structure. Due to the difference in height level, a reliable protective dielectric material layer is preserved above the resistor structure upon exposing the semiconductor material of the gate electrode structure and removing the same on the basis of selective etch recipes. Consequently, well-established semiconductor materials, such as polysilicon, may be used for the resistive structures in complex semiconductor devices, substantially without affecting the overall process sequence for forming the sophisticated replacement gate electrode structures.

  • Patent number: 8642452
    Abstract: Device structures with a reduced junction area in an SOI process, methods of making the device structures, and design structures for a lateral diode. The device structure includes one or more dielectric regions, such as STI regions, positioned in the device region and intersecting the p-n junction between an anode and cathode. The dielectric regions, which may be formed using shallow trench isolation techniques, function to reduce the width of a p-n junction with respect to the width area of the cathode at a location spaced laterally from the p-n junction and the anode. The width difference and presence of the dielectric regions creates an asymmetrical diode structure. The volume of the device region occupied by the dielectric regions is minimized to preserve the volume of the cathode and anode.
