  • Publication number: 20250095724
    Abstract: The invention provides a layout pattern of static random access memory (SRAM), which at least comprises a plurality of gate structures located on a substrate and spanning the plurality of fin structures to form a plurality of transistors distributed on the substrate, wherein the plurality of transistors comprise two pull-up transistors (PU), two pull-down transistors (PD) to form a latch circuit, and two access transistors (PG) connected to the latch circuit. In each SRAM memory cell, the fin structure included in the pull-up transistor (PU) is defined as a PU fin structure, the fin structure included in the pull-down transistor (PD) is defined as a PD fin structure, and the fin structure included in the access transistor (PG) is defined as a PG fin structure, wherein a width of the PD fin structure is wider than a width of the PG fin structure.

  • Publication number: 20250058286
    Abstract: A moisture-permeable composite membrane is manufactured by the step of subjecting a mixture to a crosslinking treatment. The mixture contains a polyisoprene, a polyurethane with a polar functional group, a crosslinking agent, and a vulcanizing agent. In the mixture, a weight ratio of the polyurethane with the polar functional group to the polyisoprene ranges from 1:0.55 to 1:6.60. A method for manufacturing the moisture-permeable composite membrane is also provided.

  • Publication number: 20250040039
    Abstract: A package assembly includes a substrate, an electronic component and a cover. The electronic component and the cover are disposed on the substrate, wherein the electronic component is located within a chamber between the cover and the substrate. A cooling liquid may be filled in a heat dissipation space of the cover, so as to dissipate the heat generated by the electronic component. Furthermore, the cooling liquid may be filled in the chamber where the electronic component is located, so as to directly dissipate the heat generated by the electronic component.

  • Patent number: 11598405
    Abstract: A planetary reducer contains: a sun gear rod, a gear assembly, a first external gear, and a second external gear. The sun gear rod includes an extension and a toothed section. The gear assembly includes a post, a first planetary gear, and a second planetary gear. Some of multiple teeth of the first planetary gear and some of multiple teeth of the second planetary gear expose outside the post. A number of the multiple teeth of the first planetary gear is different from a number of the multiple teeth of the second planetary gear. The first external gear includes a first surrounding portion and a first toothed portion which meshes with the first planetary gear. The second external gear includes a second surrounding portion and a second toothed portion which meshes with the second planetary gear.
