Patents by Inventor John P. Verboncoeur

John P. Verboncoeur 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: 11371960
    Abstract: A microscale gas breakdown device includes a first surface and a second surface. The first surface and the second surface define a gap distance. The device includes a perturbation on the first surface or the second surface. The perturbation is defined by a height value and a radius value. The device includes a current source or a voltage source configured to apply a current or a voltage across the first surface and the second surface. In response to the current or the voltage being applied, a resulting discharge travels along a first discharge path in response to being exposed to a high pressure and a second discharge path in response to being exposed to a low pressure.
    Type: Grant

  • Patent number: 5980766
    Abstract: A method of designing a reactor 10. The present reactor design method includes steps of providing a first plasma etching apparatus 10 having a substrate 21 therein. The substrate includes a top surface and a film overlying the top surface, and the film having a top film surface. The present reactor design method also includes chemical etching the top film surface to define a profile 27 on the film, and defining etch rate data from the profile region. A step of extracting a reaction rate constant from the etch rate data, and a step of using the reaction rate constant in designing a second plasma etching apparatus is also included.
