Abstract
A substrate for an electronic device, including a nitride semiconductor film formed on a joined substrate including a silicon single crystal, where the joined substrate has a plurality of silicon single crystal substrates that are joined and has a thickness of more than 2000 μm, and the plurality of silicon single crystal substrates are produced by a CZ method and have a resistivity of 0.1 Ωcm or lower. This provides: a substrate for an electronic device having a nitride semiconductor film formed on a silicon substrate, where the substrate for an electronic device can suppress a warp and can also be used for a product with a high breakdown voltage; and a method for producing the same.
