Abstract: PURPOSE:To prevent the degradation in characteristics by setting semiconductor substrates slantwise on a boat and inserting the boat into a vertical processing equipment in the oxidation, diffusion, annealing of them or film formation in such an equipment. CONSTITUTION:Semiconductor substrates 11 are slantwise set on a boat 13, and the boat 13 is inserted into a vertical processing equipment 15. The processing equipment 15 is then heated to a specified temperature using a heater 19. Further, oxidizing gas is introduced through a gas inlet 17 for oxidation, inert gas for diffusion or annealing, and film material gas for film formation. Thus the semiconductor substrates 11 are subjected to a required oxidation, diffusion, annealing, or film formation process. This prevents the formation of spontaneous oxide films and the implantation of airborne impurities into semiconductor substrates. This causes no degradation in characteristics and obtains excellent semiconductor devices.

Abstract: PROBLEM TO BE SOLVED: To provide an oil-treating agent which enables an oil to be recovered efficiently and can be scattered accurately on a spot aimed at by treating the surface of a lipophilic oil-solidifying agent with a hydrophobic material. SOLUTION: When an oil and water coexist, the surface of a lipophilic oilsolidifying agent is brought into contact with water hence the agent loses its oil-absorbing capacity and becomes easily sinkable and dispersible under the surface of water. Therefore, the surface of an oil-solidifying agent is treated with a hydrophobic material to be given water repellency, and thus, the agent comes to preferentially absorb an oil and becomes easily floatable on the surface of the sea or water and easily recoverable. For example, a hydrophobic silicon dioxide having methyl groups in its component can be pref. used the hydrophobic material. A hydrophobic silicon dioxide having an average particle size of 2-20 μm is effective. An oil-fixing agent having a particle size of 16 meshes or lower is effective.  Pref., 1-10 pts.wt. hydrophobic silicon dioxide is mixed into 100 pts.wt. oil-fixing agent.
