Abstract
To shorten a carrier lifetime in an epitaxial layer.A technical idea of the present disclosure is that a carrier lifetime distribution including, as an element, a carrier lifetime in an epitaxial layer measured at a plurality of measurement points has the following features. (1) In a case in which the average value of the carrier lifetime is defined as τ<sub>m</sub>, τ<sub>m</sub> ≤ 0.4 µs is satisfied. (2) In a case in which the standard deviation of the carrier lifetime distribution is defined as σ<sub>τ</sub>, σ<sub>τ</sub> ≤ 0.5 τ<sub>m</sub> is satisfied.
