Abstract:
PURPOSE: An extreme ultraviolet photoresist film with pentacene and a method for forming the same are provided to be used in a semiconductor process with a width of less than 30 nm by forming the photosensitive film for the extreme ultraviolet radiation having the thickness of less than several nm. CONSTITUTION: The pentacene is evaporated in vacuum on the solid sample by using the thermal evaporation(S200). The solid sample deposited with the pentacene is radiated with the extreme ultraviolet(S210). The pentacene on a portion where the ultra violet ray is not radiated is removed by heating the solid sample deposited with the pentacene(S230).

Abstract:
A patterning method using a polyatomic molecule is provided to perform a minute surface pattering by using an extreme ultraviolet, a soft X ray, and a polyatomic molecule. A molecule layer(102) is formed by absorbing a polyatomic molecule on a surface of a solid. The polyatomic molecule is NH2 or H2O. A pattern is formed by selectively irradiating an extreme ultraviolet or a soft X-ray on a part of the surface of the molecule layer. A silicone substrate on which the molecule layer is formed is positioned inside a chamber of an ultra high vacuum state. A molecule pattern is formed by absorbing a functional molecule to the pattern.
Abstract:
A patterning method using monatomic molecule is provided to realize the surface patterning elaborate and minute by using the extreme ultraviolet radiation with short wave length. The monatomic molecule is absorbed to the surface of the solid and forms the molecule layer. The contaminant layer is formed on the surface of the formed molecule layer. The extreme ultraviolet radiation or the soft X-ray(Soft X-ray) is selectively irradiated onto the surface of the formed contaminant layer and the pattern is formed. The silicon substrate in which the contaminant layer is formed is positioned within the chamber with the ultra-high vacuum state, the extreme ultraviolet radiation or the soft X-ray is irradiated.

PURPOSE: A manufacturing method of a germanium nano crystalline is provided to secure the structural stability by forming a germanium nitride barrier in nano units around the germanium nano crystalline. CONSTITUTION: A manufacturing method of a germanium nano crystalline(500) comprises the steps of: forming a germanium nitride thin film by a ionized nitrogen gas on a germanium board(100); and forming the germanium nano crystalline surrounded by the germanium nitride film through post-heating the germanium nitride thin film. The ionized nitrogen gas is obtained by direct current ion gun in the form of a hot filament. The ionized nitrogen gas is usually in the N2+ status. The step of forming germanium nitride thin film operates in the room temperature. The step forming germanium nitride thin film operates in the pressure of 0.5×10-6-10×10-6 torr.

Abstract:
A method for manufacturing a nano crystalline-silicon in a silicon-based nano structure is provided to control the size and density of a nano silicon nitride by employing a post-thermal process with respect to the nano silicon nitride at nitrogen gas atmosphere. Nitrogen gas is injected into a chamber of a vacuum state and then ionized therein. Nano silicon nitride is formed on a surface of a silicon substrate by using a sample current that is generated by the ionized nitrogen ion gas. The ionized nitrogen ion gas is generated by using a DC(Direct Current) ion gun of a hot-filament type. Nano crystalline-silicon is formed in the nano silicon nitride through a post-thermal process at nitrogen gas atmosphere.
