  • Publication number: 20250107117
    Abstract: A Schottky diode includes a substrate with an epitaxy layer on which a cathode region and an anode region are defined. A cathode structure and an anode structure are formed in the cathode region and the anode region respectively and horizontally separated by a distance. The anode structure includes a plurality of p-type doped regions diffused from the epitaxy layer toward the substrate, with an interval is formed between adjacent two p-type doped regions. A backside metal film and a backside protection layer are sequentially formed on a back surface of the substrate. Since the manufacturing of the Schottky diode does not involve wire bonding and molding processes, the overall thickness of the Schottky diode is reduced and heat dissipation is improved. With the backside metal film on the back side of the substrate, an equivalent resistance and a forward voltage of the Schottky diode can be reduced.

  • Publication number: 20250075989
    Abstract: A liquid-cooling heat sink includes a substrate, a fin assembly, and a housing. The substrate has a longitudinal direction. The fin assembly is arranged on the substrate and includes multiple fins arranged at interval to form flow channels along the longitudinal direction. Each flow channel includes an inlet and an outlet opposite to each other. A turbulence structure divides a cross-section of at least one of the flow channels into at least two diverging passages. The housing arranged on the substrate covers the inlets and includes an inlet port and a chamber. Accordingly, the number of fins may be increased in a fixed space, and each flow channel has a smaller cross-sectional area to increase flow velocity of a dielectric liquid. Moreover, this reduces the flow resistance of the dielectric liquid in a turbulent flow area in each flow channel to improve the heat dissipation efficiency.

  • Publication number: 20250048493
    Abstract: Techniques pertaining to power saving by data throughput pattern prediction in wireless communications are described. A user equipment (UE) determines whether a probability of a first value being greater than a second value is higher than a threshold. The UE triggers a radio resource control (RRC) connection release with a network responsive to the probability being higher than the threshold. The first value represents a succeeding continuous duration of no uplink (UL) and downlink (DL) data. The second value represents an RRC inactivity timer duration plus a threshold duration.

  • Publication number: 20250048706
    Abstract: A sidewall protection layer is formed on sidewall spacers of a dummy gate structure of a semiconductor device prior to etching an underlying fin structure to form a source/drain recess. The sidewall protection layer enables the profile of the source/drain recess to be precisely controlled so that etching into residual dummy gate material near the source/drain recess is minimized or prevented. The sidewall protection layer may be removed or retained in the semiconductor device after formation of the source/drain recess. The sidewall protection layer reduces the likelihood of the source/drain regions of the semiconductor device contacting the metal gate structures of the semiconductor device after the dummy gate structures are replaced with the metal gate structures. Thus, the sidewall protection layer reduces the likelihood of electrical shorting between the source/drain regions and the metal gate structures.

  • Patent number: 12219747
    Abstract: SRAM designs based on GAA transistors are disclosed that provide flexibility for increasing channel widths of transistors at scaled IC technology nodes and relax limits on SRAM performance optimization imposed by FinFET-based SRAMs. GAA-based SRAM cells described have active region layouts with active regions shared by pull-down GAA transistors and pass-gate GAA transistors. A width of shared active regions that correspond with the pull-down GAA transistors are enlarged with respect to widths of the shared active regions that correspond with the pass-gate GAA transistors. A ratio of the widths is tuned to obtain ratios of pull-down transistor effective channel width to pass-gate effective channel width greater than 1, increase an on-current of pull-down GAA transistors relative to an on-current of pass-gate GAA transistors, decrease a threshold voltage of pull-down GAA transistors relative to a threshold voltage of pass-gate GAA transistors, and/or increases a ? ratio of an SRAM cell.
