Paper Abstract

Experiments on GaAs polycrystal formation for isolation were made by using a combined system of a focused-ion-beam implanter with molecular-beam-epitaxy equipment. We obtained 0.7-μm-wide micropolycrystals of an aspect ratio of 3.5 above 160-keV-Be-implanted (more than lx1015 cm-2) GaAs epilayers. Micropolycrystals exhibited almost planar form and high resistivity even with donor doping of 3.2x10l8 cm-3. Single crystal regions adjacent to the micropolycrystals had good crystal quality which was confirmed by microscopic Raman spectroscopy. This new technique of micropolycrystal formation is attractive for planar isolation processing of GaAs devices with novel structures.
