20140362272 | METHOD OF GENERATING PIXEL ARRAY LAYOUT FOR IMAGE SENSOR AND LAYOUT GENERATING SYSTEM USING THE METHOD - A method of generating a pixel array layout for an image sensor (wherein the image sensor includes a plurality of unit pixels, and each of the plurality of unit pixels includes a plurality of transistors) includes forming each unit pixel to include a shallow trench isolation (STI). The STI is between a deep trench isolation (DTI) area and one of a p-well region and source and drain regions of each transistor. The p-well region is below a gate of each of the transistors, and the DTI area is filled with at least two materials. | 12-11-2014 |
20140374868 | IMAGE SENSOR AND METHOD OF MANUFACTURING THE SAME - An image sensor includes a plurality of photo detectors and a plurality of trench isolations configured to isolate the photo detectors from each other. Each of the trench isolations includes a plurality of films in a multi-layer structure. A method of manufacturing an image sensor includes forming a plurality of trench isolations to isolate a plurality of photo detectors from each other, forming a first film in each of the trench isolations, and forming a second film that constructs a multi-layer structure together with the first film. | 12-25-2014 |

20110073761 | APPARATUS FOR DETECTING RADIOACTIVITY OF INTERNAL PARTS AND EXTERNAL PARTS OF WHOLE BODY - An apparatus for detecting radioactivity of a whole body is disclosed. which is The apparatus for detecting radioactivity of a whole body is divided into upper and lower parts, the upper and lower parts are divided into front, rear, left and right portions, respectively, a radioactivity detection unit is installed at each of the front, rear, left and right portions, radioactivity values detected by each of the radioactivity detection units are compared and analyzed such that radioactivity values detected by the radioactivity detection units positioned at upper front and rear parts are compared, radioactivity values detected by the radioactivity detection units positioned at upper left and right parts are compared, and also radioactivity values detected by the lower radioactivity detection units are compared in the same manner, thus determining whether or not the internal parts or external parts of the body of a detection target have been contaminated by radioactivity. | 03-31-2011 |
20120055521 | SEGMENTAL ULTRASONIC CLEANING APPARATUS FOR REMOVING SCALES AND SLUDGE ON TOP OF TUBE SHEET IN HEAT EXCHANGER - Disclosed herein is a segmental ultrasonic cleaning apparatus configured to remove scales and/or sludge deposited on a tube sheet. The segmental ultrasonic cleaning apparatus includes a plurality of segment groups arranged in a ring shape on a top surface of a tube sheet along an inner wall of the steam generator, in which each of the segment groups includes an ultrasonic element segment and a guide rail support segment loosely connected to each other by metal wires through hand holes located at a lower portion of the steam generator, such that ultrasound waves radiated from an ultrasonic transducer in each of the ultrasonic element segments travels along the surface of the tube sheet, with the segment groups tightly connected in the ring shape by tightening the metal wires via wire pulleys of flange units. | 03-08-2012 |
