Latest Patents

One of his latest patents is the "Ultrasensitive high Q-factor AT-cut-quartz crystal microbalance femtogram mass sensor." This device is designed to detect environmental contaminants, diseases, and acute medical conditions related to heart failure. It identifies pathogens or troponins before infection or damage to heart muscles using an ultrasensitive high Q-factor AT-cut quartz crystal microbalance (QCM) that can measure from a single picogram to a single femtogram. The device features a set of five disks of a QCM with a 10 mm diameter and a fully coated bottom electrode. The upper electrode has a center dot with varying diameters labeled as 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm. The full coating denotes an electrically continuous thickness of at least one monolayer. Measured parameters from the five disks include Q-factors, impedance, dissipation factors (D), and frequency shift (Δf). Q-factors are utilized to calculate the Allman deviation σ(τ), and measured frequencies are converted to mass sensitivity using the Sauerbrey mass sensitivity coefficient (K).

Another significant patent is the "Non-contact measurement of the dopant content of semiconductor layers." This system and method allow for the non-contact measurement of the dopant content of semiconductor material by reflecting infrared (IR) radiation off the material. The radiation is split into two beams, which pass through pass band filters of differing wavelength ranges. By comparing the energy levels passed through each filter, the dopant content can be calculated by referencing a correlation curve made up of known wafer dopant content for that system.
