Abstract:
Provided are β-substituted Morita-Baylis-Hillman (MBH) derivatives, pharmaceutically acceptable salts, hydrates, solvates and stereoisomers thereof. The derivatives may be prepared by preparing β-iodo-MBH esters from a variety of carbonyl compounds such as aldehydes and ketones, or imines in the presence of a Lewis acid as a basic backbone, and substituting iodide on a vinyl position with a variety of substituents. In addition, the β-substituted MBH derivatives have an excellent pharmaceutical effect in preventing and treating cancer.
Abstract:
Provided are a plasma-damage-free sputter gun, which is capable of forming a layer at high speed, a sputter apparatus including the sputter gun, a plasma processing apparatus using the sputter gun, and a method of forming a layer using the sputter gun. The sputter gun includes: a yoke plate having a single-sided or double-sided opening; and a plurality of magnets disposed on the yoke plate at regular intervals. Each of the magnets includes upper and lower portions that are integrally formed and have different magnetic poles, and the magnets are arranged in a line. Accordingly, it is possible to form a layer at high speed without causing plasma damage using the above-described gun, apparatuses, and method.
Abstract:
The present invention provides a method of cutting nonmetal including glass stably, by which the glass substrate for fabricating a module of a display such as TFT-LCD, PDP and OLED can be cut fast and stably with precision without causing a damage to the substrate to enhance productivity and throughput. The present invention includes the steps of generating a laser beam by an Nd-YAG oscillator (10) using a laser diode as a light source, converting the laser beam generated from the Nd-YAG laser oscillator (10) to a short wavelength of a 200~400nm UV area by a wavelength converter, converting the laser beam generated from the Nd-YAG laser oscillator (10) the short wavelength to the laser beam having an ultra short pulse of 1~100ns through Q-switching, guiding the laser beam to a torch (6), condensing to apply the guided short wavelength laser beam to a specific location on a nonmetallic substrate, and allowing the substrate and the laser beam to make relative movements to cut the substrate into a predetermined shape.
Abstract:
Provided are a twin target sputter system for thin film passivation, which generates high density plasma between the same-shaped targets opposite to each other to thereby form a film at a high speed, and a method of forming the film using the same. The twin target sputter system for thin film passivation includes: a vacuum chamber; a substrate supporter which supports a substrate in the vacuum chamber; a pair of sputter guns each of which faces the substrate, and comprises a yoke plate opened to one side or opposite sides and a plurality of magnets disposed on the yoke plate at regular intervals; targets which are mounted on the pair of yoke plates, respectively; a gun supporter which supports the pair of sputter guns; and a power supply which supplies electric current to the targets, wherein the plurality of magnets each comprises upper and lower parts, the upper and lower parts are formed as a single body and different in magnetic polarity from each other, and the plurality of magnets are aligned in a line, and wherein the gun supporter or the substrate supporter is movable in the chamber. Using the twin target sputter system for thin film passivation and the method of forming a film using the same, an organic light emitting diode (OLED) and an organic thin film transistor (OTFT) can be fabricated by a simple thin film process without an encapsulation process using the existing metal can or glass substrate, thereby simplifying the process and lowering initial investment costs for fabricating the OLED.
