And an Si3N4 film 5 is formed on the whole reverse side at low temperatures (-700 deg.C) to protect the distortion layers. Next, heat treatment is applied to the substrate 1 at 700-1,000 deg.C for 10-60hr under a dry oxide atmosphere to generate defective layers 6 in the substrate 1. Then, an SiO2 film on the surface grown with the defective layers 6 is removed and the substrate 1 is housed in an epitaxial growth furnace to grow an epitaxial layer 2 by guiding H2 carrier gas and SiH4 gas. In this way, it is possible to minimize the density of microdefects 4 generating on the layer 2 as low as -1X10<3> pieces/cm<2> by gettering geometric effect by the distortion layers 3, the film 5 and the defective layers 6 by low temperature oxidation.

Title: Traveling table unit
Inventor: HORI KOUHEI
IPC: F16C3/02
Filed: 1977-12-13
Abstract: PURPOSE: To fulfill high-precision table traveling and positioning without high- precision alignment and fabrication.  
     CONSTITUTION: Phosphor bronze spring piece 7a which is elastic in the Y direction perpendicular to the traveling direction. In addition, spring piece 7c which is elastic in the Z direction perpendicular to the X direction is connected via a board. Then, the other terminal of spring piece 7c is connected to X table 3. In this structure, rod 8 and table 3 can be connected together with precision even if motor 15, the traveling control system at scerew 10 side and table 5 at table 3 side are different in size one another. Since the flexible shaft of connection part 7 is elastic in traveling direction, the movement of the rod is transmitted to table 3 accurately. Highly-precise positioning can therefore be attained only by precisely forming the XY table 5 side and traveling control system side separately.

The vacuum-controlled valve 12 is operated by the vacuum in suction passage  3 transmitted through vacuum passage 13. That is, it is closed at the time of high-speed, high- load operation of engine when the vacuum in suction passage 3 is lowered, so as to stop supply of  the secondary air and to thereby prevent overheating of catalyst means 7. Further, a normally- closed electromagnetic valve 14 is also provided in the secondary-air passage 9, and a minimal-  flow by-pass passage 15 is provided in the manner by-passing the electromagnetic valve 14. On  the other hand, there are provided an O 2 -sensor 16 with its top end portion exposed in combustion  chamber 4 and a control circuit which energizes electromagnetic valve 14 and opens the same in  response to the output signal from the O 2 -sensor 16 in case that actual mixture ratio is higher than  theoretical mixture ratio. With such an arrangement, overheating of catalyst can be prevented  since unnecessary secondary air is not supplied at the time of lean combustion.

Title: Resist removing method
Inventor: SHIMOKAWA SHIGEKI
IPC: G03F7/30
Filed: 1985-07-08
Abstract: PURPOSE:To remove by exfoliation the negative type EB resist film on a mask substrate in a short time by performing a wet etching method by a method wherein, when an unnecessary resist is removed, hydrogen peroxide is brought into contact with water-soluble organic solvent. CONSTITUTION:When an unnecessary resist is going to be removed after the necessary pattern is formed on a photomask or a semiconductor element, hydrogen peroxide is brought into contact with a water-soluble organic solvent. The desirable quantity of hydrogen peroxide to be used is 50-70%. As the water-soluble organic solvent, an organic solvent wherein 20% (weight) or more of water is soluble is used, and dimethylsulfoxide and the like, for example, is considered suitable as the above-mentioned organic solvent. When the water solubility of said water-soluble organic solvent is low, a pure-water rinsing process to be performed after the resist is removed by exfoliation can not be performed easily in a short period of time, and the organic solvent is liable to remain. So the above-mentioned state of low water-solubility of organic solvent is undesirable.
