  • Publication number: 20240087980
    Abstract: A semiconductor device includes a substrate, a dielectric layer disposed over the substrate, and an interconnect structure extending through the dielectric layer. The dielectric layer includes a low-k dielectric material which includes silicon carbonitride having a carbon content ranging from about 30 atomic % to about 45 atomic %. The semiconductor device further includes a thermal dissipation feature extending through the dielectric layer and disposed to be spaced apart from the interconnect structure.

  • Patent number: 9510977
    Abstract: A wound dressing for covering a wound is formed of at least one absorbing member and a plurality of elongated activated carbon fibers. The at least one absorbing member is made of a foamed polymeric material and includes a plurality of pores. The activated carbon fibers are distributed in the at least one absorbing member and partially protrude into the pores. Each of the activated carbon fibers has a diameter of 2-15 ?m and a length of 40-1500 ?m. In light of the above, the tissue fluid leaking from the wound can be absorbed by the absorbing member to prevent the wound from soakage and the activated carbon fibers inside the absorbing member can emit far-infrared rays to promote the blood circulation around the wound for quickening healing of the wound.

  • Publication number: 20160166802
    Abstract: An antibacterial catheter includes a body having a urine passage, and an antibacterial carbon material disposed in the urine passage. The antibacterial carbon material has a BET specific surface area in a range between 500 m2/g and 1800 m2/g, and contains a plurality of pores including micropores that have a diameter less than 2 nm. The antibacterial carbon material has a micropore-to-pore volume ratio ranging from 30% to 50%. Because the antibacterial carbon material is disposed in the urine passage of the catheter, the bacteria outside the human body may not easily enter into the urinary bladder and the bacteria inside the urinary bladder can be destroyed, such that the urinary system can be effectively prevented from the bacterial infection.

  • Publication number: 20150366718
    Abstract: A three dimensional wound dressing includes a foam body having a planar bottom surface and a convex arc-shaped top surface. The three dimensional wound dressing can be placed into a cavity wound in such a way that the top surface is abutted against an inner wall and a bottom of the cavity wound to effectively absorb wound exudate therefrom. Because the integrity of the foam body of the wound dressing can be maintained after the wound dressing absorbs the wound exudate, a user or a medical staff can conveniently remove and replace the wound dressing.

  • Patent number: 9125963
    Abstract: A wound dressing for covering a wound includes a textile layer woven by polyacrylonitrile-based activated carbon fiber, and an absorbent layer provided on one side of the textile layer away from the wound. The activated carbon fiber is produced by polyacrylonitrile oxidized fiber in a moisturized carbon dioxide atmosphere at the temperature of 700° C. to 1200° C. for 1 to 60 minutes. The material of the absorbent layer is cotton, alginate, poly vinyl alcohol, or a combination thereof. The water absorbing ability of the absorbent layer is superior to that of the textile layer. Because the textile layer does not produce dust and can keep dry, the hard-to-heal wounds can be prevented.

  • Publication number: 20150061171
    Abstract: A method of manufacturing wound dressing, first adding the activated carbon fibers into a foam precursor where each of the activated carbon fibers has a diameter of 2-15 ?m and a length of 40-1500 ?m. The foam precursor is made of a polymeric material, and the activated carbon fibers is 0.1-5 wt % of the activated carbon fibers plus the polymeric material. Then foaming the foam precursor to make it become an absorbing member having a plurality of pores where the activated carbon fibers partially protrude into the pores. Thus, the tissue fluid leaking from the wound can be absorbed by the absorbing member to prevent the wound from soakage and the activated carbon fibers inside the absorbing member can emit far-infrared rays to promote the blood circulation around the wound for quickening healing of the wound.

  • Publication number: 20120288670
    Abstract: A film capable of emitting far infrared rays is composed of a surface layer and a carbonic layer coating the surface layer. The carbonic layer includes carbon of at least 60 wt %. When the film is applied to the human skin, the temperature of the skin can be heightened and the blood circulation can be enhanced, so the absorbability of the active ingredients in the film by the human skin can be enhanced. Beside, the film can resist ultraviolet rays to prevent the skin from ultraviolet injury.
