Abstract: A deposition method capable of forming an oxide film with a predetermined film thickness ratio using a deposition gas with which a small film thickness ratio is obtained and a deposition gas with which a large film thickness ratio is obtained. When forming an oxide film having a larger film thickness on the surface of a substrate than on the bottom surface of the hole so that the film thickness ratio of the oxide film formed on the surface of the substrate to the oxide film formed on the bottom surface of the hole becomes a predetermined ratio, plasma is generated from a gas mixture including tetraethoxysilane and oxygen to form an oxide film and then plasma is generated from a gas mixture including silane and nitrous oxide.

Abstract: An internal anchor board-up system for windows is disclosed. The internal anchor board-up system may include an exterior window cover, one or more interior clamping beams, and bolts or fasteners connecting the cover to the beam. The exterior cover is preferably transparent, such as a plexiglass cover, so that the internal anchor board-up system is substantially more aesthetically pleasing than traditional board-up systems relying upon plywood. Further, a transparent plexiglass or acrylic cover is stronger and harder to cut through than plywood.
