  • Publication number: 20230241862
    Abstract: A device for protecting a body from damage The protective device comprises an outer protective cover, the outer protective cover comprising a thermal energy conduction element for transferring thermal energy through at least part of the outer protective cover and an inner assembly located adjacent the outer protective cover, the inner assembly comprising a thermal energy transfer device adapted to transfer thermal energy to and/or from the thermal energy conduction element. The thermal conduction element comprises a graphite-like or pyrolytic graphite-like material and the thermal energy transfer device comprises a thermal energy transfer fluid.

  • Publication number: 20210078309
    Abstract: There is provided a composite structure, comprising a protective structure comprising a plurality of ballistic layers arranged as a stack; and an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure. The ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb a force acting on the protective structure. A part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers.

  • Patent number: 6799907
    Abstract: Provided is a method for increasing an etching selectivity of photoresist material. The method initiates with providing a substrate with a developed photoresist layer. The developed photoresist layer on the substrate is formulated to contain a hardening agent. Next, the substrate is exposed to a gas, where the gas is formulated to interact with the hardening agent. A portion of the developed photoresist layer is then converted to a hardened layer where the hardened layer is created by an interaction of the hardening agent with the gas. Some notable advantages of the discussed methods of increasing the selectivity of a photoresist include improved etch profile control. Additionally, by combining fabrication steps such as the hardening of the photoresist in an etch chamber, downstream etching processes may be performed without having to transfer the wafer to an additional chamber, thereby improving wafer throughput while minimizing handling.
    Type: Grant
