英文摘要 | PURPOSE:To reduce dispersion in composition of an epitaxial layer, in manufacturing a semiconductor element having a double heterostructure, by providing a slanted bottom part of a holder, which is located directly beneath an injecting port, so that used solution does not remain. CONSTITUTION:A boat is placed in the reacting of a liquid epitaxy apparatus. Temperature is increased to 700-800 deg.C in a hydrogen atmosphere. Then the temperature is kept for a specified time period. Thereafter, the boat is slowly cooled at a constant temperature decreasing speed. When the temperature is decreased to a growth starting temperature, a solution well 71 and the like are moved to the direction of an arrow (m) by one cell. At this time, a piston 42 on the solution 62 is pushed down with a tunnel 5. The solution 62 is injected to a gap formed with a substrate wafer 2 from an injecting port 9. The injected solution 62 is moved leftward in the Figure between the substrate wafer 2 and the container wall. Then the solution falls through a hole 93 at the left end and flows into a waste liquid well 8. Since a bottom part 92 of a lower holder beneath the injecting port 9 is slanted, the used solution does not remain. |
