  • Patent number: 6964875
    Abstract: Accurate determination of gate dielectric thickness is required to produce high-reliability and high-performance ultra-thin gate dielectric semiconductor devices. Large area gate dielectric capacitors with ultra-thin gate dielectric layers suffer from high gate leakage, which prevents the accurate measurement of gate dielectric thickness. Accurate measurement of gate dielectric thickness of smaller area gate dielectric capacitors is hindered by the relatively large parasitic capacitance of the smaller area capacitors. The formation of first and second dummy structures on a wafer allow the accurate determination of gate dielectric thickness. First and second dummy structures are formed that are substantially similar to the gate dielectric capacitors except that the first dummy structures are formed without the second electrode of the capacitor and the second dummy structures are formed without the first electrode of the capacitor structure.

  • Patent number: 6743666
    Abstract: A method of making a semiconductor device includes thickening source and drain regions. After a field effect device having a source region, a drain region, and a gate, is formed, a layer of semiconductor material is deposited on the device by a directional deposition method, such as collimated sputtering. Then the semiconductor material is selectively removed from side walls on either side of the gate, such as by isotropic back etching, leaving thickened semiconductor material in the source and drain regions, and on the gate.

  • Patent number: 6737337
    Abstract: A method of manufacturing a semiconductor device includes forming a buried insulator layer of a semiconductor-on-insulator (SOI) wafer with a dopant material, such as boron, therein. The insulator material with the dopant material may be formed by a number of methods, for example by thermal oxidation of a semiconductor wafer in the presence of an atmosphere containing the dopant material, by co-deposition of the insulator material and the dopant material, or by co-implantation of an insulator material and the dopant material. The dopant material may be the same as a dopant material in at least a region (e.g., a source, drain, or channel region) of a semiconductor material layer which overlies the insulator layer. The dopant material in the buried insulator layer may advantageously reduce the tendency of dopant material to migrate from the overlying material to the insulator layer, such as during manufacturing operations involving heating.
