Abstract: FIELD: camouflage covers for war material, such as tanks, ships, rockets and missiles, special satellites. SUBSTANCE: suppressing screen is cellular structure whose cells are joined together to form regular hexahedral truncated pyramids terminating into hollow paraboloid of revolution whose wall thickness is two to four times thinner than wedge-shaped wall of pyramid. Wall inclination angle and wall thickness are interrelated by expression l= l+h ctg(90-α),, where lis wedge-shaped wall thickness with one incline plane; lis wall thickness at base; h is pyramid height; 90-α is wall inclination angle; at h=100 mm, and treatment tolerance of +-0.05 mm, angle. With modular manufacture of cells, pyramid walls are wedge-shaped and have two incline planes. In this case, l= l+2h ctg(90-α).. Inner surfaces of cells are covered with thirty-layer insulating coat with alternating layers of high and low refraction indices; thickness of each layer is 120-150 nm. On external side, cell walls are hermetically sealed by radio-transparent material coat. Beam suppression effect is ensured by relation between dimensions of pyramid base an total depth of cells. The latter is two to four times greater than pyramid base of which three fourths fall on pyramid and one fourth, on paraboloid. Thermal protection is afforded by self- contained, self-tracking, and self-adjusting cell vacuum system; for the purpose, cells are interconnected through holes measuring 5*6 mm in walls at pyramid top and sections are interconnected via air lines and common manifold with vacuum pump; common manifold provided with check valve and vacuum recorder. EFFECT: improved camouflage of war material against radar beams at various incidence angles, matched frequencies with waveform and linear dimensions of small objects, nonlinear radar and multiposition radar signals, barely visible objects, nonlinear radar and multifrequency signals of multiposition radars, reduced effectiveness of radars in selecting signals reflected both from moving and motionless targets; provision for self-contained, self- tracking, and self-adjusting thermal protection against aerodynamic heating for aerospace vehicles.

IPC: H01L21/312
Filed: 2003-04-01
Abstract: Preparation methods and stabilization processes for low k polymers that consist of sp2C-X and HC-sp3Cα-X bonds. A preparation method is achieved by controlling the substrate temperature and feed rate of the polymer precursors. One stabilization process includes a post annealing of as-deposited polymer films under the presence of hydrogen under high temperatures. The reductive annealing of these films is conducted at temperatures from -20 DEG C to -50 DEG C to +20 DEG C to +50 DEG C of their Reversible Crystal Transformation ("CRT") temperatures, then quenching the resulting films to -20 DEG C to -50 DEG C below their "CRT" temperatures. The reductive annealing is conducted before the as-deposited film was removed from a deposition system and still under the vacuum. "Re-stabilization" processes of polymer surfaces that are exposed to reactive plasma etching are also disclosed; thus, further coating by barrier metal, cap layer or etch-stop layer can be safely applied.
