Abstract: A semiconductor device includes: a drift region that is arranged on a main surface of a substrate, and has a higher impurity concentration than the substrate; a first well region that is connected to the drift region; and a second well region that is arranged adjacent to the first well region and faces the drift region. The second well region has a higher impurity concentration than the first well region. A distance between the source region that faces the drift region via the first well region and the drift region is greater than a distance between the second well region and the drift region, in a direction parallel to the main surface of the substrate. A depletion layer extending from the second well region reaches the drift region.

Abstract: A blowby gas treatment device includes a pressure control valve, a fresh air induction pipe, a first blowby gas pipe, a second blowby gas pipe, a shutoff valve, a one-way valve, and a PCV valve. A leak diagnosis includes a first-stage diagnosis to determine whether or not falling of a pressure in a crank case after closing of the shutoff valve under a non-supercharging condition is normal. A second-stage diagnosis is implemented by using an air fuel ratio feedback control, and determining whether or not a sensed intake air quantity obtained by an air flow meter is equal to an actual intake air quantity flowing into a cylinder set. When the sensed intake air quantity is equal to the actual intake air quantity, presence of an in-system leak is determined, and when the actual intake air quantity is larger, presence of an out-of-system leak is determined.
