Title: Method of gettering
Inventor: AOKI MASAKI
IPC: H01L21/322
Filed: 1989-11-14
Abstract: PURPOSE:To reduce leakage current through p-n junctions due to heavy-metal precipitation by performing rapid thermal annealing after an IG process and a preprocess to enable gettering of the precipitated heavy metal such as silicide remaining around the wafer surface. CONSTITUTION:A silicon wafer is subjected to the conventional IG process to form a layer having internal defects. Prior to a device process, LOCOS process (for forming field oxide) is performed in which wells are formed by impurity (p-type or n-type) doping. The wafer is then subjected to rapid thermal annealing at 800-1200 deg.C. For example, the wafer is heated to about 1000 deg.C at a rate of 160 deg.C/sec, held at 1000 deg.C for one minute, and cooled rapidly at a rate higher than 100 deg.C/sec, e.g. at about 110 deg.C/sec. The wafer is then subjected to the device process.

Title: Forming method for thermal transfer master sheet
Inventor: ASAMI SHINICHI
IPC: B41M5/41
Filed: 1986-12-09
Abstract: PURPOSE:To form a thermal transfer master sheet where contamination of non-image portion is reduced, by bringing a polyvinylidene chloride-containing layer of a thermal transfer recording medium into a tight contact with a document, then lapping a master base film over a dye-containing layer, thereafter projecting light containing infrared ray from the film side onto a film and forming a transfer image. CONSTITUTION:A copy having a light absorbing or heat generating image is contacted tightly with the face of a polyvinylidene chloride-containing layer of a thermal transfer recording medium comprising a dye-containing layer containing thermal sublimation or thermal vaporization dye and exhibiting adhesive property through heating, and a polyvinylidene chloride-containing layer, then the base film of a master sheet is lapped over the dye containing-layer and infrared ray is projected onto the base film. Consequently, the image portion of the copy generates heat to produce a master sheet where the dye-containing layer of the thermal transfer recording medium corresponding to the image portion is adhered onto the base film. Since the dye-containing layer corresponding to non-image portion is protected by said polyvinylidene chloride- containing layer, a clear coy having non-contaminated background can be obtained by employing said master sheet.

Filed: 1987-11-24
Abstract: PURPOSE: To provide an excellent radiation characteristic of visible light and bright illumination, by forming a thin layer made of a fluorescent material on the internal surface of a transparent box body into which the light is introduced through a fiber-optic cable. CONSTITUTION: The light such as the sunbeam, etc., guided through a fiber-optic cable 4 is emitted from the end surface of the fiber-optic cable 4. A visible component of the emitted light is diffused by a thin layer 9 made of a fluorescent material and it passes through the box body 1 to be emitted outward as the illuminating light. Components except the visible light among the light emitted from the fiber-optic cable 4 excite the fluorescent material to generate fluorescence by luminescent effect, and it is emitted outward through the box body 1. Consequently, the illuminating light can be obtained from the light components except the visible light among the light guided through the fiber- optic cable 4, as well as from the visible light, thus high illumination can be obtained.

Title: Charge transfer element
Inventor: OKADA YOSHIHIRO
IPC: H01L21/339
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To simplify the manufacturing process of a charge transfer element by automatically correcting the variation in characteristics of the element, by adding a voltage value decided based on the threshold of a transistor formed together with a reset transistor in the same process to a reset clock. SOLUTION: When, for example, the threshold of a reset transistor 4 becomes lower than a desired value, the potential at the junction between a transistor 21 and a resistor 22 rises, because the threshold of the transistor 21 also becomes lower similarly. Consequently, the lowered amount of the threshold of the reset transistor 4 is offset, because the transistor 26 tends to be turned on and an offset potential VOS becomes lower. Therefore, it becomes unnecessary to individually make setting in an offset circuit 20 constituted in the above- mentioned way at every charge transfer element and, accordingly, the manufacturing process of the element can be simplified and the manufacturing cost of the element can be reduced, because the variation in operation characteristics of each element can be relieved in the element.
