Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a crystal film and crystal substrate whose through-dislocation density are uniformly low and in which a high quality crystal layer can be easily obtained, and a method for manufacturing a semiconductor device using those. SOLUTION: An lower layer portion 13a consisting of GaN is grown, a growing temperature (1,020 deg.C) is being kept, supply of material gas of Ga is stopped for 3 minutes, and the surface of the lower layer portion 13a is etched. Thereby, a recess portion 13b is spontaneously formed at a location of each through- dislocation D1. Then, the material gas of Ga is again supplied, the upper layer portion 13c is formed. At this time, a crystal growth does not progress at the bottom of the recess portion 13b, while the growth progresses in the lateral direction at the upper side. Therefore, the recess portion 13b is covered with the upper layer portion 13c, a void portion 13b1 is formed at the end of each through-dislocation D1. The through-dislocation D1 is blocked by the void portion 13b1, thereby, the transmission to the upper portion 13c can be prevented.
