  • Patent number: 11923034
    Abstract: Disclosed herein are related to an integrated circuit including a semiconductor layer. In one aspect, the semiconductor layer includes a first region, a second region, and a third region. The first region may include a circuit array, and the second region may include a set of interface circuits to operate the circuit array. A side of the first region may face a first side of the second region along a first direction. The third region may include a set of header circuits to provide power to the set of interface circuits through metal rails extending along a second direction. A side of the third region may face a second side of the second region along the second direction. In one aspect, the first side extending along the second direction is shorter than the second side extending along the first direction, and the metal rails are shorter than the first side.

  • Patent number: 10274387
    Abstract: A pressure sensing device including a light source, at least one resonant structure, a cladding body, a first substrate and a second substrate is provided. The light source is configured to provide an original broadband light. The resonant structure includes a plurality of semiconductor rod structures arranged into a row at intervals along a single arranging direction, and each of the semiconductor rod structures has a lattice constant on the arranging direction. The original broadband light is transmitted between the semiconductor rod structures, and a resonant light is produced, wherein each of the semiconductor rod structures has a length perpendicular to the arranging direction and has a width parallel to the arranging direction, the length and the width are less than the wavelength of the resonant light. The cladding body completely covers the semiconductor rod structures of the at least one resonant structure.
