Title: Insulated gate type transistor
Inventor: KONAKA MASAMIZU
IPC: H01L29/78
Filed: 1985-08-30
Abstract: PURPOSE:To reduce parasitic capacitance between a gate and a drain, to prevent a short channel effect and a hot electron effect and to suppress punch-through between a source and the drain, by providing a low concentration region having the reverse conducting type with respect to a substrate at the side wall part of a gate insulating film. CONSTITUTION:On a one-conducting type semiconductor substrate 1, first semiconductor layers 4 and 5 including low concentration impurities having the reverse conducting type are laminated. The first semiconductor layers 4 and 5 are selectively removed, and a groove part is formed. An insulating gate film 9 is embedded in the groove part. Said first semiconductor layers 4 and 5 are made to remain at a part, where the side wall of the gate 9 is in contact with an insulating film 8. At the other part around the layers, second semiconductor layers 6 and 7, which have the same conducting type with respect to the semiconductor 1 and have the impurity concentration higher than that of the substrate 1, are formed at deeper positions. Third semiconductor layers 2 and 3, which have the reverse conducting type with respect to the semiconductor substrate 1 and include high concentration impurities, are formed at upper shallow positions on the layers 6 and 7. Said third semiconductor layers 2 and 3, which are isolated by the insulating gate 9, are made to be a source and a drain. Thus a depletion layer, which is extended on the drain and the substrate, is suppressed. Punch-through is hard to occur even in a minute element.

Title: Polishing liquid for chemicomechanical polishing and polishing method therefor
Inventor: YOSHIDA HIDEAKI
IPC: B82Y10/00
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a high polishing speed to an insulating film by providing a polishing liquid formed of pure water, polishing abrasive grains whose secondary grain size after cohesion is within a specified range and a pH regulator with a specified concentration. SOLUTION: This polishing liquid is such that the secondary grain size after cohesion of polishing abrasive grains is adjusted to 50-120 nm, the concentration of a pH regulator is adjusted to 0.9-1.8 wt.%. The manufacturing method includes the steps of first preparing pure water in which silica particles are charged as polishing abrasive grains, and secondary adding ammonia as a pH regulator to the liquid to be alkaline with a pH of 10-11. For example, according to an experiment of polishing a plasma CVD silicon oxide film, the polishing speed is increased as the ammonia concentration is heightened, and increased the smaller the secondary grain size of polishing abrasive grains is. When the secondary grain size of the polishing abrasive grain is smaller than 50 nm, dispersion is difficult, and when it is 120 nm or more, the effect of improving the polishing speed is small.  When the ammonia concentration is 1.8 wt.% or more, volatilization of ammonia is remarkable, and when it is 0.9 wt.% or less, the effect of improving polishing speed is small.

IPC: B65H45/20
Filed: 1988-07-30
Abstract: PURPOSE:To get rid of any damage to a push-in pallet and any flaw to a workpiece in making excessive bending force so as not to be imposed on the push-in pallet by paralleling the push-in pallet being inserted into a holding jaw with a straight line passing through each rotational center of two rollers, when the push-in pallet is pulled out. CONSTITUTION:A workpiece is continuously feeding to space between two rollers 1, 1' continuously rotating, and at a spot where a push-in pallet 2 of a roller one one side comes nearer to a holding claw 3 of a roller on the other, this push-in pallet 2 is projected out, having it held by the holding claw 3 of the other side roller so as to put a fold on the workpiece. In addition, at a spot where both rollers are rotated as far as the specified angle, only the push-in pallet 2 is pulled out of the holding claw 3 in leaving the workpiece left behind. At this time, since the push-in pallet 2 is paralleled with a straight line passing through each rotational center of both these rollers, it is smoothly pulled out without receiving large bending force from the holding claw 3. In this state, at a spot where these rollers are further rotated as far as the specified angle, holding of the workpiece by the holding claw 3 is released, thus folding is completed.

Abstract: PURPOSE:To form a recorded image of a selected color on a recording medium to be recorded by applying heat energy to a heat sensitive transfer recording medium, then varying the shape of a separating member to control a time until an ink sheet or an erasing sheet and the medium to be recorded are separated, and transferring a predetermined ink layer on the medium. CONSTITUTION:When a motor 43 is rotated from an initial position to a standby position, a thermal head 29 is contacted with a platen through a printing sheet and a ribbon 10 at a predetermined angle, and a head arm 28 does not rotate, but since it is rotated along a cam trace 42a of a head pressure arm 45, a pressing force F is applied by a spring 31 to a thermal head 28. At this time, when the rotating speed of a ribbon is so selected that a leaf springlike separating member 40 overcomes Fo, the ribbon starts separating from the end face X of the head. Here, when the ribbon tension is weakened, it is contacted with the platen by a pressing force F'' at a point of a distance l from the end face X of the head, the timing of separating the ribbon from a printing sheet on the platen can be delayed by l, thereby coping, for example, with various types of ribbons, such as multicolor ribbon, etc.
