  • Patent number: 12068392
    Abstract: A method and structure for doping source and drain (S/D) regions of a PMOS and/or NMOS FinFET device are provided. In some embodiments, a method includes providing a substrate including a fin extending therefrom. In some examples, the fin includes a channel region, source/drain regions disposed adjacent to and on either side of the channel region, a gate structure disposed over the channel region, and a main spacer disposed on sidewalls of the gate structure. In some embodiments, contact openings are formed to provide access to the source/drain regions, where the forming the contact openings may etch a portion of the main spacer. After forming the contact openings, a spacer deposition and etch process may be performed. In some cases, after performing the spacer deposition and etch process, a silicide layer is formed over, and in contact with, the source/drain regions.

  • Publication number: 20240241259
    Abstract: A time-of-flight (ToF) three-dimensional (3D) sensing system includes a projector that generates an emitted light corresponding to an emitted signal; a sensor that generates a received signal according to a reflected light; and a decoder that determines a distance between the sensor and the object according to the received signal. The emitted signal associated with the emitted light is generated in a basis period, and the received signal associated with the reflected light is generated by the sensor with a first phase shift with respect to a beginning of the basis period. No emitted light is generated in a supplemental period following the basis period, and the received signal has a second phase shift with respect to a beginning of the supplemental period. The distance between the sensor and the object is determined according to the first phase shift and the second phase shift.

  • Publication number: 20240243114
    Abstract: An electronic package structure includes first and second package modules combined with each other. The first package module includes a substrate and a first electronic component disposed thereon, at least one second electronic component, and an insulation film. The first electronic component and the second electronic component are adjacent to each other. The insulation film includes a base material and a foam glue body, and the foam glue body is viscous and compressible. The second package module includes a heat dissipation plate and a liquid metal and an insulation protrusion portion disposed thereon. The liquid metal is pressed by the heat dissipation plate and the first electronic component. The insulation protrusion portion covers and abuts against the insulation film to press the foam glue body through the base material so as to deform the foam glue body and enable the foam glue body to cover the second electronic component.

  • Patent number: 8913953
    Abstract: A method for controlling a function is used for an electronic device. The electronic device includes a first sensor and a second sensor. In the method for controlling the function, a first determination result is generated by determining if a neighboring object neighboring to the electronic device belongs to a target species with assist of the first sensor. A second determination result is generated by determining if the neighboring object belongs to an exception species with assist of the second sensor. The function executed by the electronic device is adjusted according to the first determination result and the second determination result.
