Title: Method of forming insulation film for separating semiconductor elements from each other
Inventor: JANG SE AUG
IPC: H01L21/76
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics and reliability of a semiconductor element, by forming its element isolation insulation film through a PBL method utilizing stacked silicon films. SOLUTION: Forming a pad oxide film 13 on a semiconductor substrate 11, a stacked polycrystalline silicon film 15 is formed on the film 13. Then, forming a nitride film 17 on the film 15, a PBL structure is formed in the laminated structure of the oxide film 13, the film 15, and the nitride film 17. Etching next the nitride film 17, the silicon film 15 is also etched in this case by a fixed thickness to form subsequently a field oxide film 19 with a predetermined thickness in the exposed portion of the silicon film 15. In this field oxidizing process, wet and dry oxidizing processes are performed in parallel with each other.  Thereby, making minimum the difference between the oxidizing velocities of the crystal grain and the crystal grain size of the polycrystalline silicon which is generated in the wet oxidizing process, the characteristic of the interface between the element isolating region and the active region of a semiconductor element is improved to make reducible the length of a bird beak by preventing the degradation of the characteristic of its gate oxide film in the succeeding processes thereof.

Title: Vibration surpression structure of floor
Inventor: NIWA MINORU
IPC: E04B5/43
Filed: 1992-05-27
Abstract: PURPOSE:To suppress vibration of a floor at a low cost by a method wherein a stretch material through which the intermediate part in a longitudinal direction of a beam is coupled to a fixing part positioned therebelow is arranged in a normal state that a tensile force is exerted. CONSTITUTION:A stretch material 5 through which the central part in a longitudinal direction of the beam, having a long span easy to vibrate, of a beam 2 is coupled to a fixed part 4 positioned therebelow is arranged in a normal state that a tensile force is exerted. In which case, the fixing part, corresponding to a lowermost stage beams 2, of the fixed parts 4 is a foundation beams 2a. The fixed parts corresponding to other beams 2 are a beam right therebelow. Thus, the stretching material 5 is operated as a column on which a normally up stress is exerted and energy of vibration generated at the beam 2 is transmitted to other beam 2 through the stretch material 5 for damping. The position in a vertical direction of a coupling part between the beam 2 and the stretch material 5 is fixed. As a result, the coupling part forms the vibration node of the beam 2, vibration of the beam 2 does not have a long period equivalent to the span thereof but has the nature of a short period equivalent to a distance between the two ends in a longitudinal direction thereof and the coupling part, and vibration of a floor is suppressed.

Title: Method for variable rectangular electron beam exposure
Inventor: OSADA TOSHIHIKO
IPC: H01L21/027
Filed: 1980-09-27
Abstract: PURPOSE:To perform an excellent exposure by a method wherein, when the rectangular beam shape is to be changed by shifting the first slit image in X and Y directions on the second slit, the matching by rotating is performed in such a manner that the beam end position on the bean transverse section on the sample surface is not shifted. CONSTITUTION:When the rectangular beam formed by the first slit 13 and the second slit 15 passes through a differentiation circuit, it is turned to a waveform a. Then, the differential waveform of the first slit 13, when passing through the second slit, which has moved on the first slit along Y axis, is changed to a waveform b. This is because of the rotation of the second slit, which retards the rotating speed by t1 seconds. In order to eliminate the deviation, the second slit is rotated is in such a manner that the t1 is zeroed. Through these procedures, the rotating positions of the two slits are matched and each side of a rectuangular electron beam can be faced sample surface in parallel, thereby enabling to perform an excellent exposure.

Filed: 1986-06-11
Abstract: PURPOSE:To surely grip cloth in cooperation with a needle section of a stationary member, by moving a movable member to a gripping position where its needle section pierces through the cloth so that the cloth is scooped up. CONSTITUTION:The fixing position of a retainer plate 22 is adjusted corresponding to the number of cloths C to be gripped at one time by a cloth gripping device 2 so that the projecting amount of needle sections 10b, 11b from through- holes 22a is adjusted to a predetermined value.

Title: Adaptive filter adapting method and device
Inventor: SUGIYAMA AKIHIKO
IPC: H04B3/23
Filed: 1986-06-10
Abstract: PURPOSE:To shorten a converging time without disturbing adaptation mutually by starting adaptation of a second filter after the convergence of a first filter is detected. CONSTITUTION:First, in order to generate an echo replica corresponding to the symmetrical component of a sending pulse, only the coefficient of an adaptive filter 13 is converted. Since an echo is sufficiently suppressed and a residual echo is small after convergence, the output of a substractor 6 comes to be almost a receiving signal and the output of an adder 9 and the output of the substractor 6 do not have the correlation. Namely, the output of a correlating device 10 is first large, later decreased and arrives at a minimum value. Consequently, when the output of the correlating device 10 is observed and comes to be shorter than the threshold specified beforehand, the adaptation of the coefficient of the adaptive filter 14 is started. At the time of converging the coefficient of the filter 14, the filter 13 executes continuously the adaptation, and when two filters are assembled, the filters are converged so that they come to be optimum.

Abstract: PURPOSE: To manufacture an NPN transistor without having any additional process, by forming the NPN transistor at the same time as a manufacturing process of a double polysilicon CMOS/FAMOS, using the same process. CONSTITUTION: An NPN transistor 4 is formed in addition to an FAMOS 1, a PMOS 2 and an NMOS 3 on a single board 12 by a single manufacturing process. Specifically, an N-type well 14 of the transistor 4 is formed at the same time as formation of an N-type well 16 of the PMOS 2, and a P<-> layer functioning as the base layer of the transistor 4 is formed at the same time as formation of a P<-> layer for threshold voltage implant of the FAMOS 1. Also, an emitter 64 of the transistor 4 is formed at the same time as formation of a source/drain layer 66 of the FAMOS 1. A collector contact region 85 of the transistor 4 is formed at the same time as formation of a source/drain region 86 of the NMOS 3, and a base contact region 88 of the transistor 4 is formed at the same time as formation of a source/drain region 90 of the PMOS 2.

Title: Semiconductor device
Inventor: HAYASHI TETSUYA
IPC: H01L29/78
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent errors in turning on of a current-controlled power element having U-shaped insulated electrodes, when a positive potential is instantaneously impressed upon a drain electrode. SOLUTION: A semiconductor device is provided with gate regions 8, which are arranged in such a way that the regions 8 are respectively sandwiched between fixed- potential insulated electrodes 6 and divided by grooves and cathode regions 14 which are insulated from a drain region 2, maintained at the same potential as that at the gate regions 8, and provided in the grooves. Then rectifying junctions are formed of the cathode regions 14 and insulating electrodes 6, and the depths of the electrodes 6 and gate regions 8 are made equivalent to each other. Since the end sections of the electrodes 6 are not surrounded by the gate regions 8, the possibility of the concentration of electric fields to the end sections of the electrodes 6 and the deterioration of the breakdown voltage of the semiconductor device by the electric field is eliminated.  Since the electrodes 6 can be formed to about equal depths with the gate areas 8, the capacitances between the gate regions 8 and source regions become larger, even if a positive potential is instantly impressed upon the drain region 2, no high potential is impressed upon the gate regions 8, and accordingly, the errors in turning on of the semiconductor device hardly occur.
