GaN substrate, method for producing GaN substrate, method for producing GaN crystal, and method for manufacturing semiconductor device |
abstract |
The present invention provides a disc-shaped GaN substrate used in a disc-shaped GaN substrate whose angle between the normal of the main surface manufactured by the paving method and the m-axis is 0° or more and 20° or less and has a diameter of 45 to 55 mm The technique of reducing the number of crystal regions to 4 or less. According to a preferred embodiment, there is provided a GaN substrate having a first main surface and a second main surface on the opposite side, and the angle between the normal of the first main surface and the m-axis is 0° or more And a disc-shaped GaN substrate with a diameter of 45 mm or more and a diameter of 20 mm or less and consisting of 4 or less crystal regions exposed on both the first main surface and the second main surface, and the 4 or less crystal regions The direction of the orthographic projection of the c-axis on the first main surface is aligned. |
