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].
A notched compound semiconductor wafer which has a plane orientation tilted from a (100) plane in a [0-10] or [010] direction and which has a notch in a [001] direction.
