Abstract:
Provided is a self-support diamond substrate made of diamond and a method for producing such a substrate. A foundation substrate is prepared, several pieces of columnar diamond made of diamond single crystal are formed over one surface of the foundation substrate, the diamond single crystal is grown from the tip of each piece of columnar diamond, each piece of diamond single crystal is brought into coalescence to form a diamond substrate layer, the diamond substrate layer is separated from the foundation substrate, and the diamond substrate is produced from the diamond substrate layer. The difference between the highest point and the lowest point in the thickness direction of the diamond substrate is more than 0 μm and 485 μm or less and the variation of the angle of the crystal axis over the entire surface of the diamond substrate is more than 0° and 3.00° or less.

Claim (Index 8):
The diamond substrate according to  claim 1 , wherein:\n a shape of the diamond substrate in a plane direction is a square shape, a circular shape, or a circular shape with an orientation flat surface, and a length of a diagonal line is 10 mm or more in case of square shape and a diameter is 0.4 inches or more in case of circular shape.
