Patents by Inventor Ken MacWilliams

Ken MacWilliams 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).

  • Publication number: 20070042580
    Abstract: An integrated microelectronic circuit has a multi-layer interconnect structure overlying the transistors consisting of stacked metal pattern layers and insulating layers separating adjacent ones of said metal pattern layers. Each of the insulating layers is a dielectric material with plural gas bubbles distributed within the volume of the dielectric material to reduce the dielectric constant of the material, the gas bubbles being formed by ion implantation of a gaseous species into the dielectric material.
    Type: Application

  • Patent number: 7049200
    Abstract: A method of forming a sidewall spacer on a gate electrode of a metal oxide semiconductor device that includes striking a first plasma to form an oxide layer on a side of the gate electrode, where the first plasma is generated from a oxide gas that includes O3 and bis-(tertiarybutylamine)silane, and striking a second plasma to form a carbon-doped nitride layer on the oxide layer, where the second plasma may be generated from a nitride gas that includes NH3 and the bis-(tertiarybutylamine)silane. The first and second plasmas may be formed using plasma CVD and the bis-(tertiarybutylamine)silane flows uninterrupted between the striking of the first plasma and the striking of the second plasma.
