Latest Patents

Andrea E Hoyt holds a patent for an "Acoustic-wave sensor for ambient monitoring of a photoresist-stripping." This acoustic-wave sensor is specifically designed for the ambient or vapor-phase monitoring of photoresist-stripping agents such as N-methylpyrrolidinone (NMP) and ethoxyethylpropionate (EEP). The sensor utilizes an acoustic-wave device, which can be a surface-acoustic-wave (SAW) device, a flexural-plate-wave (FPW) device, an acoustic-plate-mode (APM) device, or a thickness-shear-mode (TSM) device. The sensing region of the device includes a sensing film that absorbs the photoresist-stripping agent, leading to a shift in the frequency of oscillation of the acoustic wave. This shift indicates the ambient concentration of the agent, showcasing the sensor's effectiveness in real-time monitoring.
