Abstract:
Introduced here is a plasma polymerization apparatus. Example embodiments include a reaction chamber in a shape substantially symmetrical to a central axis. Some examples further include a rotation rack in the reaction chamber. The rotation rack may be operable to rotate relative to the reaction chamber about the central axis of the reaction chamber. Examples may further include two reactive species discharge mechanisms positioned around a perimeter of the reaction chamber and configured to disperse reactive species into the reaction chamber in a substantially symmetrical manner from the outer perimeter of the reaction chamber toward the central axis of the reaction chamber, such that the reactive species form a polymeric coating on surfaces of the one or more substrates during said dispersion of the reactive species, and a collecting tube positioned along the central axis of the reaction chamber and having an air pressure lower than the reaction chamber.

Claim (Index 11):
A plasma polymerization coating device comprising:\n a vacuum chamber, characterized in that a top view cross section of a chamber body inner wall along a perimeter of the vacuum chamber is: a circle with the same diameter as other top view cross sections, or a polygon with the same edge length as other top view cross sections, wherein the polygon has at least 6 edges; porous electrodes installed in the vacuum chamber proximal to the inner wall of the vacuum chamber, the porous electrodes forming a porous arched structure with a distance from the inner wall of the vacuum chamber, the porous electrodes connected with a radio frequency power source; at least two discharge cavities provided on an outer wall of the vacuum chamber in a sealed manner, each discharge cavity having a discharge source provided therein, the discharge source connected to a power source, each discharge cavity connected with one end of a carrier gas pipe, the other end of the carrier gas pipe configured for connection to a carrier gas source; at least two layers of metal grid arranged at where the discharge cavities connect to the inner walls of the vacuum chamber, the metal grid being electrically insulated from the inner wall of the vacuum chamber, the metal grid connected to a pulse power source; a monomer vapor pipe connected to the vacuum chamber, an outlet end of the monomer vapor pipe located in front of the discharge cavity, the other end of the monomer vapor pipe configured for connection to a monomer vapor source; a tail gas collecting tube vertically provided along a central axis of the vacuum chamber, one end of the tail gas collecting tube extending out from the vacuum chamber and connected to a vacuum pump, wherein holes are provided on walls of the tail gas collecting tube; and a rotation rack, for carrying a substrate to be treated, provided in the vacuum chamber, the rotation rack having a rotation shaft that is coaxial with the central axis of the vacuum chamber.
