Title: Evaluating method for particle contamination of surface of semiconductor substrate
Inventor: NARUTOMI TOSHIO
IPC: G01N21/94
Filed: 1988-03-26
Abstract: PURPOSE:To improve yield in the manufacture of a semiconductor element by a method wherein a substrate the rear of which is strained is immersed into hydrofluoric acid for removal of a natural oxide film, dipping it to and extraction from hydrofluoric acid are repeated several times, particles are attached forcibly onto the surface, and the coverage of the contaminated particles is measured for determination of the degree of contamination. CONSTITUTION:Substrates 3 introduced into a container 2 are dipped into the hydrofluoric acid tank 1 of 5% HF for five min, and natural oxidized films on the surfaces are gotten rid of. The substrates introduced into the container 2 are extracted from and introduced to the hydrofluoric acid tank 1 repeatedly one or five times, and the substrates 3 are immersed into a water tank 4 for ten min and washed, and spin-dried. Particles adhering on the surfaces of each substrate treated are measured by a laser surface inspection device. Accordingly, the semiconductor substrates, on the rears of which strain layers are shaped, are immersed repeatedly into hydrofluoric acid for simple measurement of the degree of particle contamination.

Abstract: PURPOSE:To prevent particles from occurring a member in contact with in- reactor atmosphere, a jig, etc., and also, elongate a maintenance cycle when forming a nitride film on the surface of a processed substance by a heat treatment device. CONSTITUTION:In a heat treatment device being so constituted as to form a nitride film at specified decompressed pressure and in high-temperature atmosphere on a wafer W being loaded in a reactor 3 as it is mounted on a wafer boat 10, a material having the same thermal expansion coefficient as the nitride film on the surface of the wafer W is used for the materials constituting the reactor 3 and the wafer boat 10. Since the thermal expansion coefficient is closely akin to it, cracks do not occur in the nitride film stacked on the thermal reactor 3 and the wafer 10.

Title: Manufacture of pitch based carbon fiber
Inventor: ITOU TADASHI
IPC: D01F9/14
Filed: 1982-04-30
Abstract: PURPOSE:To obtain inexpensive pitch based carbon fibers in a high carbonization yield, by heat-treating a pitchy material in a reducing solvent, advancing the thermal polycondensation while blowing a nonoxidizable compound through the solvent under a specific condition, spinning the resultant material, making the resultant fibers infusible, and carbonizing the infusible fibers. CONSTITUTION:A raw material pitchy material, e.g. coal tar pitch, is heat-treated in a reducing solvent, e.g. tetrahydroquinoline, and the solvent is recovered to give a reduced pitch. A nonoxidizing compound having <=400 deg.C boiling point at ordinary pressure in the gaseous or liquid state is then blown through the resultant pitch to distill off low-boiling components. The thermal polycondensation is further advanced to afford a pitch for spinning, which is then heated in air and made infusible. The resultant infusible fibers are heated in an inert gas atmosphere, e.g. nitrogen or helium, in a metallic furnace, etc. and carbonized and if necessary graphitized in an atmosphere, e.g. argon, in a graphitization furnace, to give the aimed pitch based carbon fibers.

Abstract: PURPOSE:To prevent the generation of a flow mark and a weld mark by forming a rib in an intersection part of a face plate and a side plate, and specifying thickness of the rib in a joint part of this rib and the side plate. CONSTITUTION:On the inside surface of a video cassette half, a rib 11 is provided from the vicinity of the reverse side of a gate part 5, joined to a side plate 4 in a joint part 12, and as for this rib 11, thickness l of a rib end part in the joint part 12 is set to 1/3 - 1/2 of thickness L of the rib in other part.
