A semiconductor a first device includes semiconductor chip and a second semiconductor chip to which different power-supply voltages are supplied, connection bonding wires connecting the first semiconductor chip and the second semiconductor chip to each other, and a sealing resin provided to fill a gap between a first lead frame on which the first semiconductor chip is mounted and a second lead frame on which the second semiconductor chip is mounted so as to cover the respective circumferences of the first semiconductor chip and the second semiconductor chip. The respective surfaces of the first lead frame and the second lead frame in the regions opposed to each other are covered with an insulating protection film including a material having higher electrical breakdown voltage than a material included in the sealing resin.

Semiconductor device

A semiconductor device includes a conductive support member, a control element, an insulating element, a driver element and a sealing resin. The conductive support member includes a first lead and a second lead. The first lead has a first pad portion. The second lead has a second pad portion. The second pad portion is adjacent to the first pad portion in a first direction perpendicular to a thickness direction of the first pad portion. The control element is mounted on the first pad portion. The insulating element is mounted on the first pad portion and electrically connected to the control element. The driver element is mounted on the second pad portion and electrically connected to the insulating element. The sealing resin covers the first pad portion, the second pad portion, the control element, the insulating element and the driver element. As viewed in the thickness direction, the first pad portion has a first edge adjacent to the second pad portion in the first direction and extending in a second direction perpendicular to the thickness direction and the first direction. The first edge has a first end and a second end opposite in the second direction. As viewed in the thickness direction, the second pad portion has a second edge adjacent to the first edge in the first direction and extending in the second direction. The second edge has a third end and a fourth end opposite in the second direction. One of the third end and the fourth end is located between the first end and the second end in the second direction.

A semiconductor device includes a conductive support member, a first semiconductor element, and a second semiconductor element. The conductive support member includes a first die pad and a second die pad separated from each other in a first direction. The first die pad and the second die pad overlap each other when viewed along the first direction. The first die pad has a first main surface mounting the first semiconductor element, and a first back surface opposing the first main surface. The second die pad has a second main surface mounting the second semiconductor element, and a second back surface opposing the second main surface. When viewed along a second direction, a distance in the first direction between the first back surface and the second back surface is larger than a distance in the first direction between the first main surface and the second main surface.

A semiconductor device includes a conductive support member, a first semiconductor element, a second semiconductor element, an insulating element, and a sealing resin. The conductive support member includes a first die pad and a second die pad, which are separated from each other in a first direction. The first die pad and the second die pad overlap each other when viewed along the first direction. When viewed along a thickness direction, a peripheral edge of the first die pad has a first near-angle portion including a first end portion in a second direction orthogonal to both the thickness direction and the first direction. The first near-angle portion is separated from the second die pad in the first direction toward the first end portion in the second direction.
