摘要： An apparatus for forming a thin film has a vacuum container to which an active gas, an inert gas or a mixture thereof is introduced, and a source of evaporation from which a substance is evaporated. A counter electrode is disposed in the vacuum container for holding a substrate for forming a thin film thereon in such a manner as to be opposed to the source of evaporation. A grid is disposed between the source of evaporation and the counter electrode and having openings which allow the evaporated substance to pass therethrough. A filament for thermionic emission is disposed between the grid and the source of evaporation. A target is also disposed between the filament and the source of evaporation for emitting sputtered particles. A power source device establishes predetermined electric potential relationships between the grid, the filament, and the target.

摘要： A thin film deposition system includes an evacuated casing in which there is introduced an active gas or an inert gas or a mixture thereof. An evaporant carried by an evaporation source in the evacuated casing is evaporated and travels toward a substrate supported on the electrode. A filament for emitting thermions is disposed between the evaporation source and the electrode, and a grid for passing the evaporated material therethrough is disposed between the filament and the electrode. Power supplies are electrically connected to the evacuated casing, the evaporation source, the electrode, the filament, and the grid, for keeping the filament negative in potential with respect to the evacuated casing and the grid. Alternatively, the evacuated casing may not be connected to the power supplies so that the grid is kept positive with respect to the filament. The grid may be of a double-layer structure, with the gas inlet means connected to the grid.

摘要： A thin film deposition system includes a vacuum or evacuated casing in which there is introduced an active gas or an inert gas or a mixture thereof. A filament emits thermions which impinge upon gas molecules to ionize them into positive ions. The ions bombard a target, from which particles are emitted toward a substrate. The particles emitted from the target are also ionized by the thermions. In the vicinity of a grid, more particles from the target are ionized by thermions which are vertically oscillated and ionized molecules of the gas. The ions are accelerated toward the substrate and bombard the substrate, thereby depositing a thin film thereon. The thin film deposition system may additionally have an evaporation source for supporting an evaporant which emit particles to be deposited on the substrate.

摘要： A thin film forming apparatus including a vacuum tank capable of introducing an active gas and/or an inert gas thereinto; a source of evaporable substance disposed in the tank; a counter electrode disposed opposite to the source of evaporable substance in the tank and holding a substrate on which a thin film is to be vapor-deposited; a filament disposed between the source of evaporable substance and the counter electrode for generating thermal electrons; a grid disposed between the filament and the source of evaporable substance, and allowing evaporated substance to pass therethrough; and power source means for putting the grid at a positive potential relative to the counter electrode. Electrons emitted from the filament form a plasma in the vicinity of the grid and ionize evaporable substance from the source of evaporable substance before being absorbed by the grid. The ionized evaporated substance then is accelerated toward the substrate for low-temperature deposition on the substrate. Therefore, even a material having low thermal resistance, such as plastics, can be used as the substrate.
