Abstract: A primer includes a layered thermite coating comprising alternating layers of metal oxide and reducing metal (thermite) deposited upon a substrate. The layered thermite coating may include a primary ignition portion adjacent to the substrate, and a secondary ignition portion deposited on the primary ignition portion. The alternating thermite layers may be thinner within the primary ignition portion than in the secondary ignition portion. The primary ignition portion is structured for sensitivity to a firing pin strike to the opposite side of the substrate. The secondary ignition portion is structured to burn at a rate that will ignite smokeless powder or other ignitable substances used in munitions.

Abstract: An energetic material having thin, alternating layers of metal oxide and reducing metal is provided. The energetic material may be provided in the form of a sheet, foil, cylinder, or other convenient structure. A method of making the energetic material resists the formation of oxide on the surface of the reducing metal, allowing the use of multiple thin layers of metal oxide and reducing metal for maximum contact between the reactants, without significant lost volume due to oxide formation. An ignition system for the energetic material includes multiple ignition points, as well as a means for controlling the timing and sequence of activation of the individual ignition points. A gas producing layer is also provided to increase pressure.

Abstract: A method for forming a metastable intermolecular composite (MIC) includes providing a vacuum level of <10?8 torr base pressure in a deposition chamber. A first layer of a first material of a metal that is reactive with water vapor is deposited, followed by depositing a second layer of a second material of a metal oxide on the first layer. The first and second material are capable of an exothermic chemical reaction to form at least one product, and the first and second layer are in sufficiently close physical proximity so that upon initiation of the exothermic reaction the reaction develops into a self initiating chemical reaction. An interfacial region averaging <1 nm thick is formed between the first layer and second layer from a reaction of the first material with water vapor. In one embodiment, the first material is Al and the second material is CuOx.

Abstract: Dielectric layers comprising a silicon oxide and having essentially constant thickness across a wafer are produced by a plasma-deposition method; in preferred processing, a wafer is supported on a surface which extends significantly past the edge of the wafer. Resulting layers may be further processed by localized etching of windows or vias, uniform layer thickness being particularly beneficial, when timed etching is used, to ensure uniformity of etched openings.

Abstract: A Si IC includes an Al-based layer which is deposited as a composite of sublayers of different composition Al-based materials. In one embodiment a first sublayer comprises an Al-Si-based alloy disposed so as to prevent substantial Si migration into the first sublayer, and a second sublayer, above the first, comprises an Al-based alloy with substantially no Si to alleviate precipitation-induced problems.
