  • Publication number: 20250031404
    Abstract: A semiconductor device may include one or more transistor structures that include a plurality of source/drain regions and a gate structure between the source/drain regions. The semiconductor device may further include one or more dielectric layers between a source/drain contact structure and a gate structure of the one or more of the transistor structures. The one or more dielectric layers may be manufactured using on oxidation treatment process to tune the dielectric constant of the one or more dielectric layers. The dielectric constant of the one or more dielectric layers may be tuned to reduce the parasitic capacitance between the source/drain contact structure and the gate structure (which are conductive structures). In particular, the dielectric constant of the one or more spacer dielectric may be tuned using the oxidation treatment process to lower the as-deposited dielectric constant of the one or more dielectric layers.

  • Publication number: 20200289425
    Abstract: Disclosed herein are drug-containing vesicles, each of which includes a carbon dot liposome (C-dot liposome) formed by a plurality of Janus particles, which are self-assembled into the C-dot liposome; and a drug encapsulated within the C-dot liposome. Also disclosed herein is a method of producing the drug-containing vesicles. The method includes, mixing a plurality of Janus particles with a drug solution (e.g., an anti-cancer drug solution) to form a mixed solution; and producing the drug-containing vesicles either by a film-hydration method or an injection method. In the film-hydration method, the mixed solution is condensed until a film-like structure is formed; and sonicating the film-like structure in a salt solution to produce the drug-containing vesicle. In the injection method, the mixed solution is rapidly injected into a salt solution to produce the drug-containing vesicle. Also encompasses in the present disclosure are methods for treating a subject afflicted with a cancer.

  • Publication number: 20110249452
    Abstract: Provided is a compound light-condensing apparatus preferably including a lens body with refractive index n, and light-incident surface and light-ejected surface. The light-ejected surface has one set of Fresnel lens. When an incident light passes through the Fresnel lens structure, a focus with focal length F is formed. Two types of Fresnel lens structure are disposed on a light-ejected surface. More particularly, plural prism bodies are orderly disposed on the second type of Fresnel lens structure. The prism bodies counted from the central line is j and two adjacent prism bodies are spaced by p. The distance Tj is from a base surface to light-ejected surface. An included angle ?j between ejected light and light-ejected surface is formed. By orderly changing the refractive angle of ejected light can be changed for achieving shorter focal length and better light condensation.
