IPC: H01L29/78
Filed: 1991-11-29
Abstract: PURPOSE:To suppress the generation of the leakage current caused by the generation of crystal defects and improve the quality of a semiconductor device, by providing the processes for embedding poly-Si in a necked part through an anisotropic etching and the process for injecting impurities into an substrate, etc., in the manufacture of the semiconductor device. CONSTITUTION:On an Si substrate 10, a poly-Si electrode 13 is formed via an oxide film 12, and the oxide film 12 is etched in an isotropic way. Then by the application of a thermal oxidation treatment, an oxide film 14 for covering the poly-Si electrode 13 and the oxide film 12 is formed thereon, and a necked part 20 is formed in the oxide film 14. Subsequently, a poly-Si 15a is deposited thereon extensively, and thereafter, by an anisotropic etching, the poly-Si is embedded in the necked part 20. Then, by the application of a thermal oxidation treatment, an oxide film 16 whose thickness becomes largeras the side of the Si substrate 10 is approached is formed on the sidewall of the poly-Si electrode 13. Also, for the formations of source and drain regions 18, 19, impurities are injected into the Si substrate 10. Therefore, any overetching can be suppressed, and the generation of crystal defects on the surface of the Si substrate 10 can be eliminated.

Title: Line of sight detector
Inventor: SHINDO OSAMU
IPC: A61B3/113
Filed: 1989-12-07
Abstract: PURPOSE:To temporarily determine the center of the pupil of an eye by regarding the intersection of a 1st and a 2nd straight line by linear approximation as a point of inflection when the edge of the pupil is not found as the intersection of a 3rd straight line and the 2nd straight line by linear approximation. CONSTITUTION:The pupil center 32 is found from the position of the edge 37 of the pupil and the direction of a line of sight is detected from the position relation between the pupil center 32 and a 1st Purkinje image PI. A processing circuit 20, on the other hand, finds the inflection point 5 as the intersection of the 1st and 2nd straight lines by linear approximation unless the inflection point 5 can be found as the intersection of the 3rd and 2nd straight lines by linear approximation. Consequently, the position of the pupil center 32 of the eye can be determined temporarily even if the intersection of the 2nd and 3rd straight lines obtained by a Newton method according to a 1st straight line can not be found by linear approximation.

Abstract: PURPOSE:To practice the error detecting of the memory area of which memory contents are updated by updating and storing data used for the error detecting for every time when the data are written in a data memory means. CONSTITUTION:In a normal processing, when data are written in the said mem ory area of a RAM 3, a writing flag is set, and when a timer interruption is generated, it is advanced to a sum checking subroutine. In the sum checking subroutine, it is judged whether the writing flag is set or not in advance, when the writing flag is set, a CPU 2 recalculates the sum value of the said memory area and stores it in a sum storing area 33, an continuously the writing flag is reset by a peripheral device control part 4. Thus, when the error detecting indication is generated, since it is detected whether there is an error in the memory contents of data memory means or not based on the data used for the storing error detecting, the error detecting of the memory area can be practiced.

Title: Automatic electronic component mounting device
Inventor: MOBARA MASAYUKI
IPC: B23P21/00
Filed: 1992-11-26
Abstract: PURPOSE:To eliminate the deterioration of the positional accuracy at the time of mounting of a component due to lost motion of a rotary system occurring when an angle of a component is corrected by rotating a suction nozzle, and hence to mount components at high speed. CONSTITUTION:When a mounting angle is O degrees, and when an angular deviation of a chip component detected by a recognition device 16 is 10 degrees, a CPU causes a rotating body to be rotated through 20 degrees in a clockwise direction by a first head rotating device 17 at a first angle correction station, and also causes the rotating body to be rotated through 10 degrees in a counterclockwise direction by a rotating device 18 at a second angle correction station, so that the rotating body is angularly positioned. If it is necessary to correct the position of the rotating body in X and Y directions due to lost motion, correction is carried out on the basis of the amount of an angular deviation stored in a RAM. When a recognized angular deviation is -5 degrees, the rotating body is first rotated through 20 degrees in a clockwise direction and then rotated through 25 degrees in a counterclockwise direction.
