20080295772 | CHEMICAL VAPOR DEPOSITION APPARATUS AND PLASMA ENHANCED CHEMICAL VAPOR DEPOSITION APPARATUS - A chemical vapor deposition (CVD) apparatus and a plasma enhanced chemical vapor deposition (PECVD) apparatus that reduce the number of fine particles inside a chamber. The CVD and the PECVD apparatuses each include a chamber; a gas injection unit that injects a gas into the chamber; a gas exhaust unit that exhausts the gas to the outside of the chamber, and is positioned facing the gas injection unit; a film formation unit that incorporates a film formation region on which a film is formed from the gas, and is positioned between the gas injection unit and the gas exhaust unit; and a electrostatic induction unit, which is positioned around a region corresponding to the film formation region in order not to overlap with the film formation region, and is connected to a voltage source that is insulated from the chamber. | 12-04-2008 |
20090121231 | THIN FILM TRANSISTORS, METHOD OF FABRICATING THE SAME, AND ORGANIC LIGHT-EMITTING DIODE DEVICE USING THE SAME - Aspects of the invention relate to thin film transistors, a method of fabricating the same, and an organic light-emitting diode device using the same. A thin film transistor according to an aspect of the invention includes a semiconductor layer formed from polysilicon in which a grain size deviation is within a range of substantially ±10%. Accordingly, aspects of the invention can improve non-uniformity of image characteristics due to a non-uniform grain size in polysilicon produced by a sequential lateral solidification (SLS) crystallization process. | 05-14-2009 |
