| 20110253823 | RAW SILICON CRUSHER - The raw silicon crusher comprises a pair of beds; and a pair of crushing surfaces on the beds crushing the quenched pure raw silicon by applying pressure; wherein each of the beds comprises a case; pure silicon members arranged inside of the case and protruding from the opening; a block of pure ice fixing the pure silicon members to the case, and each of the crushing surfaces comprises surfaces of ends of protrusions; and surface of the block of ice. | 10-20-2011 |
| 20110217486 | METHOD FOR PROCESSING A CHEMICAL VAPOR DEPOSITION (CVD) AND A CVD DEVICE USING THE SAME - A method for CVD processing, comprises the steps of: fixing both ends of a silicon substrate to a pair of electrode mounts; lowering a resistance value of the silicon substrate by raising temperature of the silicon substrate with heat from an outer heater provided outside the case; heating the silicon substrate to a temperature at which the CVD process can be started by applying electrical current, and lowering an atmosphere temperature in the CVD space by stopping the outer heater; and forming a thin film on a surface of the silicon substrate by injecting source gas into the CVD space, when the silicon substrate is heated to the temperature at which the CVD process can be started and the atmosphere temperature in the CVD space is lowered to a predetermined temperature. | 09-08-2011 |
| 20110209693 | SILICON HEATING FURNACE - The silicon heating furnace is constructed by combining two semi-cylindrical furnaces. Each of the semi-cylindrical furnaces has a semi-cylindrical housing, an insulator, heaters, and an isothermal material. Radial direction separation preventing members are arranged in inner side of both ends of circumferential direction of the housing to prevent a separation of the insulator to radial direction. End face of circumferential direction covers are fixed on the radial direction separation preventing members to cover the end faces of circumferential direction of the insulator. Cooling pipes for end faces of circumferential direction through which cooling water passed are arranged between the end faces of circumferential direction of the insulator and the end face of circumferential direction covers. | 09-01-2011 |
