Title: Manufacture of mos type semiconductor device
Inventor: YOSHIDA MASAYUKI
IPC: H01L29/78
Filed: 1983-10-14
Abstract: PURPOSE:To contrive the simplification of the manufacturing process and the improvement of element reliability by providing the processes of forming a gate electrode, forming a film for reactive ion etching, leaving a laminated film, and forming an insulation film pattern. CONSTITUTION:After a gate oxide film 32 is formed on a P type Si substrate 31, the gate electrode 33 is formed by patterning through RIE etching. Next, the resist pattern used for the patterning of the gate electrode is removed, and thereafter a thermal oxide film 34 is formed. After application of a resist film 35 over the entire surface, a resist pattern 35' is left only on the side wall of the gate electrode. On treatment with the mixed solution of H2O2 and H2SO4, only the resist pattern is removed, and only a thermal oxide film pattern 34' and a gate oxide film pattern 32' are left. Then, when As ions are implanted, the gate electrode serves as a blocking mask, and an N type source region 36 and an N type drain region 37 are formed by self-alignment method.

Filed: 1990-07-19
Abstract: PURPOSE:To laminate a nonwoven cloth and core material and to harden the center part of a polishing disk, by getting a fiber entangled, sticking it at the intersection thereof and bonding it. CONSTITUTION:A nonwoven fabric 1 and core material 2 are laminated, by extending the fiber 4 of the nonwoven fabric 1 into the core material 2, or, fibers 4, 5 are entangled with the fiber 5 of the core material 2 being extended into the nonwoven fabric 1. In this state, the nonwoven fabric 1 and core material 2 are not sticked but held in a lamination state with the fibers 4, 5 being entangled. The lamination body of the nonwoven fabric 1 and core material 2 are cut in a disk shape. An adhesive is coated on this lamination body cut in a disk shape. An abrasive grain is blown when this adhesive is not hardened yet. At this stage, the abrasive grain is sticked to the surface of a nonwoven fabric fiber 4. Moreover, the adhesive is input to a die in the state of its being not hardened, the center part is formed with its center part being thinly pressed and the adhesive is hardened in a heating furnace. A desired polishing disk is thus obtained.

IPC: G01N3/08
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a pull strength testing equipment that can absorb a counterforce, at the same time transfer a rotary force, and can be automated at the connection part between a rotary member and a pull shaft. SOLUTION: A pull strength measuring equipment is provided with a strain gauge 6c for measuring a tensile force being generated in a pull shaft 9, a storage means for storing a value that is measured by the strain gauge 6c, a comparison means for comparing the measurement value that is stored by the storage means with a value that is measured by the strain gauge 6c later, and a control means for performing control so that a peak value for stopping a motor 20 can be measured based on a result that is compared by the comparison means. Therefore, only a rupture value has been coped with conventionally but the strength of an object to be measured can be determined simply by checking the strength peak value. Also, when a storage value is smaller than the measurement value, the peak value can be determined and the storage value can be set to the peak value.

Filed: 1985-08-30
Abstract: PURPOSE:To facilitate control of a threshold voltage and so forth and realize reduction of a leakage current and improvement of dielectric strength by a method wherein a high concentration region and low concentration regions on both sides of the high concentration region are provided in a channel region and those two types of regions have identical conductive type. CONSTITUTION:P<->type regions 23 and 24 have impurity (boron) concentration of, for instance, 1X10<16>cm<-3> and a P<+>type region 20 has impurity concentration of, for instance, 5X10<16>cm<-3>. By forming a high impurity concentration region 20 between low impurity concentration regions 23 and 24 like this, although both regions are composed of P-type semiconductors, the surface potential as an MOS transistor is partially elevated and this elevated surface potential can be made to function as a energy barrier against monority carries. With this constitution, the threshold voltage of the MOS transistor can be controlled. moreover, as this controllability is realized not by increasing the impurity concentration of the substrate but by setting the concentration rather lower, a P-N junction capacitance can be reduced and reduction of a leakage current and improvement of dielectric strength can be also realized.

Filed: 1987-08-03
Abstract: PURPOSE:To provide a monitor function and to switch optical paths without moving an optical path switching part by utilizing the polarizing and separating operation of polarizing prisms, photodetecting a half of input light by a light receiving element and outputting the remaining half as output light directly. CONSTITUTION:The 1st and 2nd polarizing prisms 16a and 16b are arranged their polarizing films opposite each other, and the 1st polarizing prism 16a is used for photodetection and the 2nd polarizing prism 16b is used for optical transmission. The polarizing and separating operation of the polarizing prism 16 utilizes the difference in reflection coefficient between P polarized light and S polarized light at a Brewster angle. A half of the input light is therefore inputted to the light receiving element at all times and the remaining half becomes the output light, and when an LD is used as the light emitting element, the majority of the sent light becomes the output light at the time of optical transmission, but when an LED is used, the half of the sent light becomes the output light and a movable part functions only to cut of the light signal. Consequently, the monitoring function is provided, the optical axes of a movable block and a receptacle which switch optical axes are easily adjusted, and the cost is reduced.
