摘要:
A deposition apparatus of depositing deposition material on a wafer in a vacuum chamber includes a deposition boat installed in the vacuum chamber to vaporize the deposition material, a wafer guide on which the wafer is loaded, the wafer guide having a rotational member rotating together with the wafer, a wafer-rotation device rotating the rotational member when the wafer guide approaches, and a wafer-transfer device reciprocating the wafer guide between an inlet of the vacuum chamber, the deposition boat and the wafer-rotation device.
摘要:
Provided is a patterned deposition source unit for forming a thin film on a substrate and a deposition method using the same. The patterned deposition source unit includes a main body that includes a loading section for loading a deposition material and a cover unit, which covers openings of the loading section and has a plurality of line shaped openings. The deposition material vaporized through line shaped openings of the cover unit can be vertically deposited on the substrate which moves back and forth over the main body. The method enables the improvement in the uniformity of a thin film by preventing dispersion of the deposition material in a conventional depositor, and the improvement in the density of a thin film by increasing vapor flux per unit area by reducing the distance between the deposition source unit and the substrate.

摘要:
An electromagnetic induced accelerator based on coil-turn modulation, including inner and outer cylinders with different diameters, the cylinders being coaxially disposed to form a channel which is a spatial portion therebetween; a discharging coil wound spirally inward along the upper surface of the channel for generating plasma by inducing a magnetic field and secondary current in the channel; and inner and outer coils wound helically around along the inner surface of the inner cylinder and the outer surface of the outer cylinder in parallel with each other for accelerating plasma in the direction of a common axis of the inner and outer cylinders by offsetting the magnetic field induced in the direction of the axis.
