20120267356 | GROUNDING STRUCTURE, AND HEATER AND CHEMICAL VAPOR DEPOSITION APPARATUS HAVING THE SAME - A ground structure for a PECVD apparatus includes a ground connector is positioned in a receiving portion of a ground mount that is connected to an electrical reservoir. A cylindrical ground clamp holds the ground connector and includes an opening portion along a sidewall in a longitudinal direction. An outer surface of the ground connector makes contact with an inner surface of the ground clamp. A pair of stumbling portions are folded from an outer surface of the ground clamp and spaced apart from each other by a width of the opening portion. A ground wiring is connected to the ground clamp and the ground mount, and the ground current flows to the ground mount via the ground clamp by the ground wiring, thus the ground current is grounded to the electrical reservoir. Accordingly, the electric arc is prevented between the ground connector and the ground clamp. | 10-25-2012 |
20120061002 | METHOD OF MANUFACTURING MULTILAYER CERAMIC SUBSTRATES - In a method of manufacturing a multilayer ceramic substrate, first and second sheet stacks are formed by pressurizing a plurality of unsintered ceramic sheets, respectively. A hole is formed to penetrate through the second sheet stack. A third preliminary sheet stack is formed by positioning the second sheet stack on the first sheet stack. First and second thin films are formed at top and bottom of the third preliminary sheet stack, respectively. A third sheet stack is formed by pressurizing the first and the second thin films and the third preliminary sheet stack. The first and the second thin films are removed from the third sheet stack, thereby forming a preliminary multilayer ceramic substrate. The preliminary multilayer ceramic substrate is sintered. Accordingly, the reliability and stability of the manufacturing process for the multilayer ceramic substrate is sufficiently improved with reduced cost due to the flat molds and thin films. | 03-15-2012 |
20100327191 | Ion Implanter, Internal Structure of Ion Implanter and Method of Forming A Coating Layer in the Ion Implanter - An ion implanter includes a process chamber and a coating layer. The process chamber receives a substrate and provides a space to perform an ion implantation process on the substrate. The coating layer is disposed on an inner wall of the process chamber to reduce contamination of the substrate and includes the same material as that of the substrate. | 12-30-2010 |
