IPC: H01L27/148
Filed: 1990-11-14
Abstract: PURPOSE:To reducing afterimages without decreasing the maximum charge amount by eliminating potential recesses in a drawing of energy level generated in the most vicinity of a high-doped p<++> region and a threshold control p<+> region. CONSTITUTION:This device comprises a p-type silicon substrate 1, an n-type region 2, a CCD buried channel 3, a p-type layer 4, a threshold p<+> type region 11, a high-doped p<++> region 6, and a gate 7. A surface distance 12 between the high-doped p<++> region 6 and the threshold control p<+> region 11 is narrower than the distance 13 of a part slightly inward from the surface. Therefore, potential recesses in a drawing of energy level are eliminated in the n-type region 2 between the high-doped P<++> region 6 and the threshold control P<+> region 11, so that signal charges become easy to read. This reduces read charge remains and afterimages.

Filed: 1993-12-13
Abstract: PURPOSE:To densify an SiO2 film near its boundary and restructure a network of boundary atoms to reduce boundary level density by treating a very thin SiO film with a plasma that contains nitrogen. CONSTITUTION:An amorphous silicon film.is deposited on a glass substrate 1 by LPCVD using Si2H6. An SiO2 film 3 for gate oxide is deposited on a semiconductor layer 2 by remote plasma CVD. The film thickness is preferably 1 to 10nm; if less than 1nm the semiconductor layer may be damaged, and if more than 10nm nitrogen may not diffuse to the boundary between the semiconductor layer and the oxide film 3.

Filed: 1990-11-19
Abstract: PURPOSE:To assure stable suction without allowing water, saliva, dust, etc., to remain in a vacuum main pipe by providing a washing liquid supply tank for passing a washing liquid to the vacuum main pipe. CONSTITUTION:A stop valve 12 of a return pipe 10 is held closed and the inside of the pipe is maintained in a suction state by the operation of a suction blower 3 when solenoid valves 5 of branch pipes 4 at >=1 points are opened and the system is under use. The stop valve 12 is opened for a prescribed period of time and the blower 3 is run when all the solenoid valves 5 are put into the sealed state. The water, saliva, dust, etc., sucked from a suction adapter 7 are transported toward a liquid-gas separator 2 by the air sucked from the stop valve 12 even after the solenoid valves 5 are closed. Since the water in the vacuum main pipe 1 is removed, the inside of the main pipe 1 is always in the dry state. A prescribed volume of the washing liquid is supplied from the washing liquid supply tank 11 through the return pipe 10 to the vacuum main pipe 1 during the time when the diagnosing time ends. This washing liquid peels or dissolves the residues remaining in the main pipe 1 from the pipe wall and the residues dispersed in the washing liquid are transported to the separator 2 and are removed.
