Latest Patents

One of Long Vu's latest patents is an X-ray microanalyzer for thin films. This apparatus includes an X-ray source that irradiates a spot smaller than 500 micrometers on the surface of a sample. A first X-ray detector captures fluorescent X-rays emitted from the sample at a high angle relative to the surface. Additionally, a second X-ray detector captures X-rays from the spot at a grazing angle. The processing circuitry analyzes the signals from both detectors to determine properties of the surface layer within the irradiated area. Another significant patent involves the detection of voids in semiconductor wafer processing. This method tests the deposition and removal of materials within a recess on a sample's surface. An excitation beam is directed onto the sample, and the intensity of X-ray fluorescence is measured to determine the quantity of material deposited.
