Ian Christopher Mayes 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: 9482605
    Abstract: A cartridge suitable for use in a bond testing machine includes a plurality of a different test tools. A rotary mechanism is provided and each of the plurality of different test tools is mounted to the rotary mechanism angularly spaced from one another. A drive unit is coupled to the rotary mechanism and is configured to rotate the rotary mechanism to move each of the plurality of different test tools to and from a use position. An air interface receives compressed air from a corresponding air interface on a positioning assembly of the bond testing machine.
    Type: Grant

  • Patent number: 8680852
    Abstract: A method of detecting defects using eddy currents is disclosed. The method comprises: exciting eddy currents in a test material using an eddy current probe driven by a drive signal; detecting induced eddy currents in the test material; converting the detected signal into integer values using an analog to digital converter; and adding or subtracting the generated integer values to or from each of two accumulators, or taking no action, so that one accumulator produces a value proportional to one component of the detected signal and the other produces a value proportional to another component of the detected signal and using these values to detect the presence of a defect.

  • Publication number: 20090229997
    Abstract: A sealing ring assembly and an improved method for mounting a sealing ring into an electrochemical cell used for Electrochemical Capacitance Voltage (ECV) profiling measurements. The ring is located in a holder having at least one secondary bore providing fluid communication between a forward face of the holder and the central bore of the ring, directed parallel to but tangentially offset relative to the inner wall of the central bore so as to impart a degree of rotational flow to electrolyte entering the sealing ring through the or each secondary bore which effectively removes gas bubbles and refreshes the electrolyte. The holder facilitates ring removal with a much reduced risk of damage to the delicate sealing surface.

  • Patent number: 7113276
    Abstract: The invention relates to a method and apparatus for detecting defects in a semiconductor or silicon structure at room temperature, and in an efficient time, using photoluminescence. The invention employs the use of a high intensity beam of light preferably having a spot size between 0.1 mm–0.5 microns and a peak or average power density of 104–109 w/cm2 with a view to generating a high concentration of charge carriers, which charge characters detect defects in a semiconductor by interacting with same. These defects are visible by producing a photoluminescence image of the semiconductor. Several wavelengths may be selected to identify defects at a selective depth as well as confocal optics may be used.
