  • Publication number: 20240382098
    Abstract: A device for measuring blood pressure receives a vibration signal from a vibration sensor which is used to measure a target area. The device then converts the vibration signal into a digital signal and performs a filtering process on the digital signal. The filtering process involves removing noise around the principal component wave that corresponds to the pulsation of the target area within a specific range in the digital signal. Subsequently, based on the digital signal that has been filtered, the device determines a systolic pressure determination time point and a diastolic pressure determination time point to generate a blood pressure measurement result.

  • Publication number: 20240371962
    Abstract: In some implementations, fluorine is oxidized after dry etching an oxide layer above a source/drain contact and before cleaning. Accordingly, less hydrofluoric acid is formed during cleaning, which reduces unexpected wet etching of the source/drain contact. This allows for forming a recess in the source/drain contact with a depth to width ratio in a range from approximately 1.0 to approximately 1.4 and prevents damage to a layer of silicide below the source/drain that can be caused by excessive hydrofluoric acid. Additionally, or alternatively, the recess is formed using multiple wet etch processes, and any residual fluorine is oxidized between the wet etch processes. Accordingly, each wet etching process may be shorter and less corrosive, which allows for greater control over dimensions of the recess. Additionally, less hydrofluoric acid may be formed during cleaning processes between the wet etch processes, which reduces the etching of the source/drain contact between processes.
