Abstract
A semiconductor device includes first member that includes a switch made of a semiconductor element made from an elemental semiconductor. The first member is joined to a second member including a radio-frequency circuit including a semiconductor element made from a compound semiconductor. The switch and the radio-frequency circuit are connected by a path. The path includes an inter-member connection wire made of a metal pattern arranged on an interlayer insulating film extending from a surface of the second member to a surface of the first member or a conductive member allowing a current to flow in a direction crossing an interface where the first member and the second member are joined.
