A plasma etching method using selective polymer deposition, and a method of forming a contact hole using the plasma etching method are provided. The plasma etching method uses a method of reinforcing an etch mask by selectively depositing polymer on only a photoresist pattern, which is an etch mask. That is, a dielectric film is plasma etched for a predetermined period of time using the photoresist pattern as an etch mask, and polymer is selectively deposited on only the photoresist pattern which is thinned by plasma etching, thereby forming a polymer layer. Following this, the dielectric film is plasma etched using the photoresist pattern and the polymer layer as a mask. Thus, dielectric film etching providing high resolution and an excellent profile can be performed using the thinned photoresist pattern as a mask, and a contact hole and a self-aligned contact hole each having a very high aspect ratio, and a self-aligned contact hole having an excellent profile, can be formed.

The present invention relates to a method and a device for controlling the hand-over message transmission power of a mobile station in a mobile communication system. The present invention comprises the processes of: acquiring uplink data relating to a hand-over target base station; using the uplink data to determine the maximum transmission power of a hand-over ranging message; and transmitting a hand-over ranging message having a power level below the determined maximum transmission power to the hand-over target base station.

The present invention provides materials and methods for making proton conductive polymer, polymer membranes comprising the proton conductive polymer, membrane-electrode assemblies comprising the polymer membrane, and fuel cells comprising the membrane-electrode assemblies. The proton conductive polymer can be formed in the following manner: a) silicon inorganic polymers and silane compounds having amino groups are dissolved in a solvent to form a precursor; b) said precursor undergoes condensation polymerization to form a network of inorganic polymers; and c) the network and a reactant are contacted with one another to form the proton conductive polymer.

摘要:
In the method of forming fine patterns of a semiconductor integrated circuit, a mask layer is formed over a semiconductor structure having a first region and a second region. A portion of the mask layer over the first region is removed to expose the semiconductor structure, and sacrificial layer patterns are formed over the exposed semiconductor structure. Then, spacers are formed on sidewalls of the sacrificial layer patterns and the mask layer, and portions of the spacers are removed to create fine mask patterns. The semiconductor structure is then patterned using the fine mask patterns to create fine patterns.
