Abstract
There is provided a notched compound semiconductor crystal having the same specification even if it is turned over. With respect to a compound semiconductor wafer produced by slicing a compound semiconductor crystal having a crystal plane of (100) plane, the crystal is sliced so as to be tilted from the (100) plane in a direction of [101] or [10−1] when a notch is formed in a direction of [010], or the crystal is sliced so as to be tilted from the (100) plane in a direction of [0−10] or [010] when a notch is formed in a direction of [001], or the crystal is sliced so as to be tilted from the (100) plane in a direction of [001] or [00−1] when a notch is formed in a direction of [0−10], or the crystal is sliced so as to be tilted from the (100) plane in a direction of [010] or [0−10] when a notch is formed in a direction of [00−1].
