Abstract:
Disclosed is a paste composition for printing including conductive powders, a binder, a dispersing agent, and a solvent. The dispersing agent includes a block copolymer of polyethylene oxide (PEO)-polypropylene oxide (PPO)-polyethylene oxide (PEO), or a block copolymer of polypropylene oxide (PPO)-polyethylene oxide (PEO)-polypropylene oxide (PPO).
Abstract:
A method of forming a pattern includes forming a mask pattern on a substrate; etching the substrate by deep reactive ion etching (DRIE) and by using the mask pattern as an etch mask; partially removing the mask pattern to expose a portion of an upper surface of the substrate; and etching the exposed portion of the upper surface of the substrate. In the method, when a pattern is formed by DRIE, an upper portion of the pattern does not protrude or scarcely protrudes, and scallops of a sidewall of the pattern are smooth, and thus a conformal material layer may be easily formed on a surface of the pattern.
Abstract:
Disclosed herein are a method and an apparatus for preparing a metal composite powder by using gas spraying. The method of preparing a metal composite powder by using gas spraying includes introducing a matrix phase in a chamber, including a reinforcing phase in the chamber, melting the introduced matrix phase to form a melt, adding the reinforcing phase in the melt, stirring the melt with the added reinforcing phase to form a melt mixture, atomizing the melt mixture together with a gas to form a metal composite powder containing the reinforcing phase, and collecting the metal composite powder formed.
Abstract:
The present invention relates to a wrinkle-removing apparatus. When the wrinkle removing apparatus of the present invention adopting a vacuum suction system is tightly applied to the shallow wrinkles on a forehead or to deep wrinkles, a vacuum is created by means of the elasticity of the wrinkle-removing apparatus, in order to strongly suck and pull wrinkles outwardly from the skin. Repeated use of the apparatus with the above-described condition enables a substance such as subcutaneous fat or collagen to replace the wrinkles at the back surface of the wrinkled skin when wrinkles are pulled outwardly from the skin, and finally, skin wrinkles are removed even when the apparatus is no longer used.
Abstract:
The present invention relates to a cation-exchanged zeolite catalyst for an transiodination and a process for producing mono-iodo benzene by using it. Particularly, the cation-exchanged zeolite catalyst has a molar ratio of Si/Al from 5 to 100 and is ion-exchanged with an alkali metal or an alkaline earth metal in range of 2% to 50% of ion exchange capacity.Further, the process for producing mono-iodo benzene of the present invention comprises the step of performing a transiodination by using the cation-exchanged zeolite catalyst to produce mono-iodo benzene from reactants including benzene and one or more multi-iodo benzenes selected from the group consisting of di-iodo benzene and tri-iodo benzene.
Abstract:
Disclosed is a guidance service method and an apparatus thereof. That is, the method provides a terminal device that connects to a voice call with a step-based service menu through voice information, receives selection information of the terminal device based on the step-based service menu, through the voice call, and displays, in the terminal, a service screen configured based on the selection information of the terminal device that is received through the voice call, in parallel with reception of the voice information, and thereby improving understanding and convenience of the guidance service for a user.

Abstract:
A semiconductor heterostructure having: a substrate (SS); a buffer layer (h); a spacer layer (d, e, f); a barrier layer (b, c); and which may also include a cover layer (a) is provided. The barrier layer is doped (DS); and the barrier and spacer layers are made of one or more semiconductors having wider bandgaps than the one or more materials forming the buffer layer, the heterostructure being characterized in that: the barrier layer comprises a first barrier sublayer (c) in contact with the spacer layer, and a second barrier sublayer (b), distant from the spacer layer; and in that the second barrier sublayer has a wider bandgap than the first barrier sublayer. The invention also relates to a HEMT transistor produced using such a heterostructure and to the use of such a transistor at cryogenic temperatures.

Disclosed are a process module, a fabrication method thereof, and a substrate processing method using the process module. The process module includes a structure in which cell substrates are fixed on a carrier member by an adhesive according to a preset alignment standard. The fabrication method includes aligning the cell substrates according to a preset alignment standard, applying an adhesive to at least one of surfaces facing each other between the cell substrates and the carrier member, and attaching the cell substrates to the carrier member by using the adhesive. The substrate processing method includes performing the substrate processing process of the cell substrates at the same time by using the process module integrated with the cell substrates. The substrate processing method selectively includes calibrating the alignment standard for the cell substrates in the substrate processing process to an alignment state of the cell substrates in the process module.
