Abstract
A liquid-phase epitaxial growth device has a reservoir holder (1), a slider (14) movably mounted below the reservoir holder to enable each reservoir (2, 3, 4, 5) to be selectively uncovered so as to allow semiconductor melt in each reservoir to pass through each aperture (15, 16, 17, 18) in the slider, a movable substrate holder (22) for receiving one or more semiconductor substrates (25, 26) that are placeable below each aperture, and a member (19) for receiving semiconductor melt from each aperture when it is uncovered by movement of the substrate holder. A locking mechanism (30, 31, 32, and 33) enables the slider to be locked to the reservoir holder at one or more substantially fixed positions.
