    Abstract: This invention provides a process for producing a large-size group III nitride crystal in which the dislocation density of at least the surface thereof is wholly low. The production process is characterized in that it comprises the step of providing a base substrate (1) comprising a group III nitride seed crystal having a main area (1s) and a polarity reversed area (1t) having polarity reversed in direction to the main area (1s), and the step of growing a group III nitride crystal (10) by a liquid phase method on the main area (1s) and the polarity reversed area (1t) in the base substrate (1), and a first area (10s) having a higher growth rate of the group III nitride crystal (10) grown on the main area (1s) covers a second area (10t) having a lower growth rate of the group III nitride crystal (10) grown on the polarity reversed area (1t).

    Abstract: This invention provides a method for manufacturing a gallium nitride crystal, which, when a gallium nitride crystal is grown using a gallium nitride substrate including a translocation aggregation region and an inversion region is used as a seed crystal substrate, can manufacture a gallium nitride crystal, which has low translocation density and, at the same time, has good crystallinity and, in addition, is less likely to cause cracking upon polishing after slicing. In embedding the translocation aggregation region and the inversion region (17a) for growth of a gallium nitride crystal (79), the gallium nitride crystal (79) is grown at a growth temperature of above 1100°C and 1300°C or below. According to this constitution, the translocation taken from the translocation aggregation region and inversion region (17a) can be reduced, and the occurrence of new translocation on the translocation aggregation region and inversion region (17a) can be suppressed. Good crystallinity of the gallium nitride crystal (79) can be realized, and, at the same time, cracking is less likely to occur in polishing after slicing of the gallium nitride crystal (79).
