Abstract: Provided is a method of depositing a thin film on a substrate using an impulse feeding process. The method includes performing a second reaction gas continuous feeding process of continuously feeding a second reaction gas into a chamber in which the substrate is installed, and performing a number of times, during the second reaction gas continuous feeding process, a process cycle including a first reaction gas feeding process of feeding a first reaction gas into the chamber and a first reaction gas purge process of purging the first reaction gas that is not adhered onto the substrate. The second reaction gas continuous feeding process includes a second reaction gas impulse process of feeding the second reaction gas at an impulse flow rate greater than a basic flow rate during the first reaction gas purge process.

Abstract: A camera module comprises a lens array including at least one lens, a lens accommodating unit having an inner space, in which the lens array is arranged, and an incident hole, and a housing mounted on a circuit board. The housing has a counter-engagement part engaged with an engagement part formed at the lens accommodating unit such that the lens accommodating unit is moved in the direction of the optical axis. An image sensor has an image area on which light is focused. The image sensor is electrically connected to the circuit board. A filter is disposed between the lens array and the image sensor. The filter includes a transparent medium through which light introduced along the optical axis is transmitted to the image area, and a prevention film for preventing electromagnetic waves generated by the image sensor from being emitted out of the housing.

Abstract: An electrodeless lighting system includes: a resonator installed at an outlet of a waveguide guiding microwave energy generated from a magnetron and defining a cavity allowing light to pass therethrough while resonating microwave therein; a bulb positioned in the resonator and enclosing a radiation material for emitting light by the microwave energy; and one or plural microwave concentrating units installed at the inner circumferential surface of the resonator and concentrating microwave energy discharged from the outlet of the waveguide to the bulb. By concentrating microwave to electrodeless plasma bulb positioned inside the resonator, a stability in an initial lighting and light efficiency can be enhanced.

Abstract: Provided is an in-situ thin-film deposition method in which a TiSix/Ti layer or TiSix/Ti/TiN layer can be continuously deposited. The method serves to deposit a thin layer as a resistive contact and barrier on a loaded wafer and is performed in a thin-film deposition apparatus including a transfer chamber having a robot arm therein and a plurality of chambers installed as a cluster type on the transfer chamber. The method includes depositing a TiSix layer on the wafer by supplying a first reactive gas containing Ti and a second reactive gas containing Si to a first chamber; and transferring the wafer to a second chamber using the transfer chamber and depositing a TiN layer on the TiSix layer.

Abstract: A thin film deposition apparatus that can effectively use a chemical source having a high vaporization temperature is provided. The thin film deposition apparatus includes a chamber for depositing a thin film on a wafer, a canister for accommodating a liquid chemical source to be supplied to the chamber, and a vaporizer for vaporizing the liquid chemical source bubbled in the canister and providing the vaporized chemical source to the chamber. The vaporizer is installed on a top surface or lateral surface of the chamber by an adaptor block to be incorporated into the chamber. A first gas line between the vaporizer and the chamber is formed within the adaptor block.

Each of the plurality of bodies has a plurality of holes to allow a refrigerant pipe to pass through the plurality of bodies. The connecting part connects the plurality of bodies to each other, with a recess being provided on the connecting part to allow the connecting part to be easily bent. A manufacturing method includes preparing a plurality of fins arranged to provide two or more parallel rows of fin arrays, preparing an end plate provided on a side of the fin arrays to connect the fin arrays to each other, inserting a refrigerant pipe into the fin arrays and the end plate to provide an assembly including the refrigerant pipe, the fin arrays, and the end plate, and bending the assembly at a predetermined angle around the connecting part of the end plate.

Abstract: Provided is a method of depositing a metal nitride film having a multilayer structure and different deposition speeds on a substrate. The method is performed by forming a first lower metal nitride film on the substrate at a first deposition speed, forming a second lower metal nitride film on the first lower metal nitride film at a second deposition speed, and forming an upper metal nitride film having a large content of nitrogen (N) on a lower TiN film which is formed by the forming of the first lower metal nitride film and the second lower metal nitride film, at a third deposition speed, to improve stability with respect to exposure to air/moisture. The deposition speed of the metal nitride film having a multi-layer structure satisfies a relationship that the second deposition speed ?the first deposition speed ?the third deposition speed.
