  • Publication number: 20240128626
    Abstract: A transmission device includes a daisy chain structure composed of at least three daisy chain units arranged periodically and continuously. Each of the daisy chain units includes first, second and third conductive lines, and first and second conductive pillars. The first and second conductive lines at a first layer extend along a first direction and are discontinuously arranged. The third conductive line at a second layer extends along the first direction and is substantially parallel to the first and second conductive lines. The first conductive pillar extends in a second direction. The second direction is different from the first direction. A first part of the first conductive pillar is connected to the first and third conductive lines. The second conductive pillar extends in the second direction. A first part of the second conductive pillar is connected to the second and third conductive lines.

  • Publication number: 20240120239
    Abstract: A method for modulating a threshold voltage of a device. The method includes providing a fin extending from a substrate, where the fin includes a plurality of semiconductor channel layers defining a channel region for a P-type transistor. In some embodiments, the method further includes forming a first gate dielectric layer surrounding at least three sides of each of the plurality of semiconductor channel layers of the P-type transistor. Thereafter, the method further includes forming a P-type metal film surrounding the first gate dielectric layer. In an example, and after forming the P-type metal film, the method further includes annealing the semiconductor device. After the annealing, and in some embodiments, the method includes removing the P-type metal film.

  • Patent number: 11848608
    Abstract: A control circuit for controlling a switching regulator includes a timer, a comparator, a driver circuit and a controller. The timer generates an input signal indicative of whether a predetermined amount of time has elapsed since an activation of a drive signal. The comparator is configured to compare a feedback voltage with a reference voltage to generate a comparison signal. The driver circuit is controlled by a control signal to generate the drive signal according to one of the input signal and the comparison signal. The control signal indicates whether a mode is enabled. When the mode is enabled, the driver circuit is configured to generate the drive signal according to the input signal. The controller is configured to, in response to an activation of the input signal, generate the control signal according to a result of a comparison of the feedback voltage with another reference voltage higher than the reference voltage.
