  • Patent number: 11221431
    Abstract: A sensor for monitoring CO2 in a fluid regardless of the phase properties of the fluid, i.e., regardless of whether the fluid contacting the window is a liquid water-based phase, a liquid oil-based phase, a mixture of liquid water and liquid oil-based phases, or a gas phase. The sensor includes an internal reflection window for contacting with the fluid. A mid-infrared light source directs a beam of mid-infrared radiation into the window and the beam is internal reflected at an interface between the window and the fluid. The reflected beam is passed through three narrow bandpass filters which preferentially transmit mid-infrared radiation over bands of wavelengths corresponding to absorbance peaks of water, oil and CO2. The amount of CO2 is determined from the intensities of the mid-infrared radiation passing through the three filters.

  • Patent number: 10823683
    Abstract: A method for detecting defects in deep features like channel holes, via holes or trenches based on laser-enhanced electron tunneling effect. A substrate having thereon a film stack is provided. First and second deep features are formed in the film stack. The first deep feature has a sacrificial oxide layer disposed at its bottom. The second deep feature comprises an under-etch defect. The sacrificial oxide layer has a thickness of less than 50 angstroms. The substrate is subjected to a laser-enhanced electron beam inspection process. The substrate is scanned by an electron beam and illuminated by a laser beam. The laser beam induces electron tunneling across the sacrificial protection layer, thereby capturing a bright voltage contrast (BVC) signal corresponding to the first deep feature, and detecting a dark voltage contrast (DVC) signal corresponding to the second deep feature.
