Abstract: A method for manufacturing a nitride semiconductor device including: forming an N-type region in a nitride semiconductor layer; implanting ions of an acceptor element into a region under the N-type region in the nitride semiconductor layer; and forming a first P-type region under the N-type region by subjecting the nitride semiconductor layer to heat treatment and activating the acceptor element. The forming the N-type region includes implanting ions of a donor element into the nitride semiconductor layer such that concentration of the donor element in the N-type region is equal to or greater than concentration of the acceptor element in the first P-type region. The implanting ions of the acceptor element into a region under the N-type region includes implanting ions of the acceptor element such that concentration of the acceptor element in the first P-type region is 1×1019 cm?3 or more and 1×1021 cm?3 or less.

Abstract: A navigation ECU includes a route calculator section, an automated driving distance calculator section, and a display processor section. The route calculator section calculates a plurality of route candidates to a destination designated by a user. The automated driving distance calculator section calculates an automated driving enabled distance that is a distance of a road segment, where a vehicle is able to be run by an automated driving, with respect to each of the plurality of route candidates. The display processor section displays a route selection screen view containing the information which indicates an automated driving enabled distance versus a full length, with respect to each of the plurality of route candidates.
