Abstract
A semiconductor device includes: a first circuit pattern having a recessed part in a planar view; a second circuit pattern positioned in the recessed part; a plurality of semiconductor chips bonded onto the first circuit pattern; and wires connecting top electrodes of the plurality of semiconductor chips to the second circuit pattern, wherein a width of the second circuit pattern increases from upstream to downstream on a current path by which a current flows through the second circuit pattern, and the first circuit pattern has a step in a planar view on a side of the recessed part, and a width of the recessed part increases in a tiered way to match an increase in the width of the second circuit pattern.
