IPC: H01S5/00
Filed: 1993-09-10
Abstract: PURPOSE:To provide a method of molecular beam epitaxy for a substrate having patterns of grooves, in which the substrate is rotated for such control that it is flattened with the patterns maintained. CONSTITUTION:A deposition source 4 of a group V element, As, and a deposition source 2 of a group III element, Ga, in the same direction to the source 4 and a Ga deposition source 3 in the symmetrical direction are laid out directed at a GaAs substrate 1 having a groove in at a beam incident angle smaller than an inclination angle of a groove side wall. While the substrate 1 is being rotated, when the substrate makes a growth with the As deposition source 4 and the Ga deposition source in the same direction, a GaAs crystal thin film will grow so as to keep the groove shape. On the other hand, when the growth proceeds with the Ga deposition source 3 symmetrical to a vertical axis of the substrate, the growth is promoted to flatten the groove shape.
