Patent JP-S63211678-A (JP)
Title: Manufacture of insulated-gate field-effect transistor
Inventor: YAGI ATSUO
IPC: H01L29/78
Filed: 1987-02-26
Abstract: PURPOSE:To prevent the generation of a parasitic capacity which is caused by the parts of the source and drain which creep under the thin gate insulating film by forming a channel forming region in self alignment with the section in which a gate is to be formed, or the section on which the thin part of the insulating layer is deposited. CONSTITUTION:On a preformed low impurity concentration region 12, an insulating layer 13 is formed which has a thin part 13A in a part in which a channel is to be finally formed, or a position in which a gate section is to be formed, and the remaining of which is made to be 13B, and with this as a mask an impurity doping is performed. Accordingly, a region in which the channel is to be formed is formed in alignment with the position where the thin part 13A is to be formed, or the position where a gate insulating film 16 is to be formed, and the respective opposed edges 17S, 17d of a source region 18S and a drain region 18d are constructed by the low impurity concentration region 12. With this, these regions are prevented from being opposed through the thin gate insulating film 16 to a gate electrode 15, so that the generation of a parasitic capacity is drastically reduced between the source and drain add the gate.

Filed: 1987-02-26
Abstract: PURPOSE:To enable the title device to be very small by providing a construction wherein the impurity regions have a uniform concentration distribution and make a stepped junction with a semiconductor substrate, and the junction is protected by a polysilicon layer. CONSTITUTION:After forming a gate insulating film 2 on the principal surface of a p-type semiconductor substrate 1, epitaxial layers 3-1, 3-2 are grown into which an n-type impurity was doped with a high concentration, and thereafter, by forming a polysilicon layer and oxidizing the surface of this layer, a gate electrode 6 is formed simultaneously with a source region 4-1 or a drain region 4-2. Since the semiconductor layers 3-1, 3-2 of a uniform concentration are provided as the impurity regions, the source region 4-1 or drain region 4-2 of a low sheet resistance and shallow junction can be constructed, and in addition, since the polysilicon layer is provided, a contact can be provided without destructing the shallow junction.

Patent JP-S62203757-A (JP)
Title: Grinder
Inventor: HIROSE SHIGEO
IPC: B24B49/16
Filed: 1986-03-01
Abstract: PURPOSE:To enable automatic grinding under constant pressure, by engaging a driving gear fitted on the drive shaft of a motor, with a driven gear fitted on a rotary shaft, and by coupling the rotary shaft and the drive shaft to each other through a link, and providing a spring between the link and a case at the side of the drive shaft. CONSTITUTION:When a ground surface 24 has a projection 25, a grindstone 15 comes into contact with the projection so as to ascend to compress a spring 19. As a result, pushing torque Ts increases so that the rotation of the grindstone 15 is retarded. For that reason, a link 16 is turned counterclockwise so that the spring 19 is compressed further. Consequently, the grindstone 15 goes up from the ground surface 24 so that a pushing force Fp decreases. Because of the decrease in the pushing force Fp, the spring 19 acts to turn the link 16 clockwise to increase the pushing force. In other words, if the height of the projection 25 is large, the increase in the pushing torque Ts is absorbed by a differential mechanism including the link 16, so that the grindstone 15 comes into contact with the ground surface 24 under constant pressure, regardless of the height of the projection 25.
