  • Patent number: 6261931
    Abstract: A method for growing high-quality gallium nitride over a substrate is disclosed. The method comprises growing first layer with a high dislocation density over the substrate, a second layer having a high number of point defects and a reduced dislocation density as compared to the dislocation density of the first layer over the first layer, and a third layer having a reduced number of point defects as compared to the second layer over the second layer. The resulting gallium nitride is semi-insulating, which inhibits parasitic current flow and parasitic capacitive effects, yet it not so insulating that electron flow in adjacent transistor channels is inhibited.
