1. A semiconductor device, comprising:

  • a first semiconductor layer of a first conductivity type;

    a second semiconductor layer of a second conductivity type on the first semiconductor layer;

    a third semiconductor layer of the first conductivity type on the second semiconductor layer, the second semiconductor layer being between the first and third semiconductor layers in a first direction;

    a first plurality of source elements each extending along the first direction from the third semiconductor layer into the second semiconductor layer and spaced from each other along a second direction perpendicular to the first direction;

    a first gate electrode extending along the first direction from the third semiconductor layer into the second semiconductor layer and spaced from the first plurality of source elements in a third direction perpendicular to the first and second directions, the first gate electrode extending continuously along the second direction parallel to the first plurality of source elements;

    a source electrode electrically connected to first plurality of source elements; and

    a drain electrode on the first semiconductor layer such that the first semiconductor layer is between the second semiconductor layer and the drain electrode in the first direction.
