Patents by Inventor Dale P. Hallock

Dale P. Hallock has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6028339
    Abstract: A dual work function CMOS device and method for producing the same is disclosed. The method includes: depositing a first layer of a doped material, either n-type or p-type, over a substrate to be doped; defining the areas that are to be oppositely doped; depositing a second layer of an oppositely doped material over the entire surface; and subjecting the entire CMOS device to a high temperature, drive-in anneal. The drive-in anneal accelerates the diffusion of the dopants into the adjacent areas, thereby doping the gate polysilicon and channels with the desired dopants. A nitride barrier layer may be utilized to prevent the second dopant from diffusing through the first layer and into the substrate beneath.
    Type: Grant

  • Patent number: 5226732
    Abstract: An improved contactless temperature measurement system is provided which includes a workpiece, a chamber containing the workpiece with the walls thereof being substantially transmissive to radiation at wavelengths other than a given wavelength and substantially reflective at the given wavelength to remove the dependence of the apparent or measured temperature on the workpiece emissivity variations or fluctuations.

  • Patent number: 4481046
    Abstract: A method for diffusing a conductivity determining impurity in a semiconductor substrate and making electrical contact thereto by depositing a conductive layer made of a rare earth hexaboride material containing a predetermined amount of silicon in it over a surface portion of the substrate and heating the substrate for a predetermined period of time at a predetermined temperature which is sufficient to cause boron from the hexaboride material to diffuse into the adjoining portion of the substrate to modify its conductor characteristics. At the same time a good electrical ohmic contact is established between the conductive layer and the adjoining substrate portion while the conductive layer retains its conductivity even after the outdiffusion of some of its boron into the substrate during the heat treatment.
