Cornelius A H A Mutsaers 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).

  • Semiconductor device with a superparaelectric gate insulator
    Patent number: 8106434
    Abstract: A semiconductor device includes a channel region 18 of semiconductor, a conductive gate electrode 12 adjacent to the channel region 18 and a gate dielectric 10 between the conductive gate electrode 12 and the channel region 18. The gate dielectric 10 is formed of a material that is a ferroelectric in bulk but in a superparaelectric state. The gate dielectric may be for instance of formula AXO3, where A is a group I or II element, and X is titanium, niobium, zirconium and/or hafnium. Such a gate dielectric 10 may be formed for example by low temperature deposition of the gate dielectric 10 or by using dopants of metal oxides to prevent domain growth, or both.
    Type: Grant
