Abstract:
A method for manufacturing a GaN-based compound semiconductor device, comprising the steps of:forming an In.sub.x Ga.sub.1-y N (0.ltoreq.x.ltoreq.1) layer on a substrate at a temperature T0 with a first carrier gas comprising an inert gas;forming an Al.sub.y Ga.sub.1-y N (0.ltoreq.y.ltoreq.1) layer on the In.sub.x Ga.sub.1-x N layer at the temperature T1 (T0.ltoreq.T1) with a second carrier gas different from the first carrier gas, andkeeping the first carrier gas while adjusting the temperature from T0 to T1.
