  • Patent number: 11961912
    Abstract: The present application provides a semiconductor device and the method of making the same. The method includes recessing a fin extending from a substrate, forming a base epitaxial feature on the recessed fin, forming a bar-like epitaxial feature on the base epitaxial feature, and forming a conformal epitaxial feature on the bar-like epitaxial feature. The forming of the bar-like epitaxial feature includes in-situ doping the bar-like epitaxial feature with an n-type dopant at a first doping concentration. The forming of the conformal epitaxial feature includes in-situ doping the conformal epitaxial feature with a second doping concentration greater than the first doping concentration.

  • Publication number: 20240105515
    Abstract: A method includes forming a first low-dimensional layer over an isolation layer, forming a first insulator over the first low-dimensional layer, forming a second low-dimensional layer over the first insulator, forming a second insulator over the second low-dimensional layer, and patterning the first low-dimensional layer, the first insulator, the second low-dimensional layer, and the second insulator into a protruding fin. Remaining portions of the first low-dimensional layer, the first insulator, the second low-dimensional layer, and the second insulator form a first low-dimensional strip, a first insulator strip, a second low-dimensional strip, and a second insulator strip, respectively. A transistor is then formed based on the protruding fin.

  • Patent number: 10644378
    Abstract: An electronic device for detecting an antenna element includes a sensing circuit, a comparison circuit, an interface circuit, an internal LNA (Low Noise Amplifier), a bypass path, and a selection circuit. The sensing circuit generates a sensing voltage according to an input current. The input current is relative to the antenna element. The comparison circuit compares the sensing voltage with a first reference voltage, so as to generate a first control voltage. The sensing circuit is coupled through the interface circuit to an RF (Radio Frequency) node. The interface circuit is configured to reduce the interference between the antenna element and the electronic device. The selection circuit selectively couples the internal LNA or the bypass path to the RF node according to the first control voltage.

  • Patent number: 5715531
    Abstract: A synchronous tracking filter circuit for use in a broadcast satellite tuner that comprises four varactors and a strip-shaped inductor plate or pcb-printed strip line which produces a resonant frequency. The circuit is used in a doubly tuned resonant circuit to incorporate the tracking with the frequency changes of a voltage controlled oscillator (VCO) synchronously. The circuit can also control the image interference. This type of design is applicable in the tuner of an indoor broadcast satellite receiver unit to act as the synchronous tracking filter of input frequencies.
