  • Publication number: 20240172434
    Abstract: A semiconductor device includes a stacked gate structure, a plurality of stacks and a first conductive layer. The stacks are disposed aside the stacked gate structure and arranged along both a first direction and a second direction perpendicular to the first direction, wherein the stacks are extended continuously along the first direction and segmented in the second direction. The first conductive layer is disposed between segmented portions of the stacks along the second direction, wherein top surfaces of the segmented portions of the stacks are higher than a top surface of the first conductive layer.

  • Patent number: 11925017
    Abstract: A semiconductor device is provided. The semiconductor device includes a substrate, a stacked gate structure, and a wall structure. The stacked gate structure is on the substrate and extending along a first direction. The wall structure is on the substrate and laterally aside the stacked gate structure. The wall structure extends along the first direction and a second direction perpendicular to the first direction. The stacked gate structure is overlapped with the wall structure in the first direction and the second direction.

  • Patent number: 11733378
    Abstract: The present disclosure provides a detection system and a detection method. The microphone of the detection system receives the response signal formed according to the shape of the sealed cavity. The conversion unit transfers the response signal in the time domain to the frequency domain signal in the frequency domain. The calculation unit obtains every frequency value corresponding to the frequency gradient being zero of each frequency waveform which is chosen of the response signal. The average unit averages every frequency value corresponding to the frequency gradient being zero of each chosen frequency waveform into the average frequency value and outputs an average frequency value. The determination unit determines whether the average frequency value is located in the corresponding frequency tolerance range, so that the wearing status of the in-ear earphone is confirmed.

  • Patent number: 10969906
    Abstract: The present disclosure provides a control method for a touch device. The control method of the touch device allows the plurality of pressure sensors to be activated to detect the pressure on the touch position of the touch panel while the capacitive touch sensor is probably invalid and the touch device is abnormal. Therefore, the touch device works continuously when the capacitive touch sensor is probably invalid.
