  • Publication number: 20240113112
    Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.

  • Patent number: 11944970
    Abstract: A microfluidic detection unit comprises at least one fluid injection section, a fluid storage section and a detection section. Each fluid injection section defines a fluid outlet; the fluid storage section is in gas communication with the atmosphere and defines a fluid inlet; the detection section defines a first end in communication with the fluid outlet and a second end in communication with the fluid inlet. A height difference is defined between the fluid outlet and the fluid inlet along the direction of gravity. When a first fluid is injected from the at least one fluid injection section, the first fluid is driven by gravity to pass through the detection section and accumulate to form a droplet at the fluid inlet, such that a state of fluid pressure equilibrium of the first fluid is established.

  • Patent number: 9533130
    Abstract: A syringe includes a sleeve and a pressure vessel with high pressure fluid therein. The sleeve further comprises a sleeve piston. As the high pressure vessel contacts the sleeve piston, and a bump on the sleeve piston destroys the airtight status of the high pressure vessel. While the seal of the high pressure vessel is removed, the compressed fluid flows into the sleeve through the opening of the high pressure vessel and the hole of the sleeve piston. When the closed end of the sleeve moves closer to the closed end of the sleeve piston, the fluid in the sleeve is pressed and flows out of the sleeve through the sleeve hole of the sleeve.

  • Patent number: 9398659
    Abstract: An integrated LED lamp and a data transmission circuit and a synchronization circuit thereof are provided. Integrated LEDs of the present invention only need two pins, such that the originally existing LED package method can be adopted. In addition, by using two pins, the present invention can synchronize the LEDs or further update a displayed pattern. Because the old package technology has been well developed, the present invention can avoid the risk of the yield reduction caused by the new package technology in addition to reductions of the wire and the manufacturing cost.
