Reliability of a semiconductor module is improved. In a resin mold step of assembly of a semiconductor module, an IGBT chip, a diode chip, a control chip, a part of each of chip mounting portions are resin molded so that a back surface of each of the chip mounting portions is exposed from a back surface of a sealing body. After the resin molding, an insulating layer is bonded to the back surface of the sealing body so as to cover each back surface (exposed portion) of the chip mounting portions, and then, a TIM layer is bonded to an insulating layer. Here, a region of the TIM layer in a plan view is included in a region of the insulating layer.

Method of manufacturing semiconductor module and semiconductor module

Method of packaging power semiconductor module including power transistors

An improvement is achieved in the heat dissipation property of an electronic device including power transistors. A semiconductor module includes first and second packages included in an inverter circuit. In the first package, a semiconductor chip having a high-side power transistor is embedded. In the second package, a semiconductor chip having a low-side power transistor is embedded. At the both wide surfaces of the first and second packages, first metal electrodes electrically coupled to respective collector electrodes of the power transistors and second metal electrodes electrically coupled to respective emitter electrodes of the power transistors are exposed. To the first and second metal electrodes of the first and second packages, four respective bus bar plates having areas larger than those of the first and second metal electrodes are joined.

Electronic device

An electronic device includes a first substrate, a wiring substrate (second substrate) disposed over the first substrate, and an enclosure (case) in which the first substrate and the wiring substrate are accommodated and that has a first side and a second side. A driver component (semiconductor component) is mounted on the wiring substrate. A gate electrode of a first semiconductor component is electrically connected to the driver component via a lead disposed on a side of the first side and a wiring disposed between the driver component and the first side. A gate electrode of a second semiconductor component is electrically connected to the driver component via a lead disposed on a side of the second side and a wiring disposed between the driver component and the second side.

Power module having control substrate mounted above power substrate with control substrate drivers located between the power substrate power transistors

An electronic device includes: a substrate having an upper surface (front surface) on which a semiconductor chip is mounted, and a lower surface (back surface) opposite to the upper surface; and a housing (case) fixed to the substrate through an adhesive material. The housing has through-holes each formed on one short side and the other short side in an X direction. The substrate is disposed between the through-holes. A part of the upper surface of the substrate is fixed so as to face a part of a stepped surface formed at a height different from that of a lower surface of the housing. Further, an interval (distance) between a part (stepped surface) extending along a short side of the housing in the stepped surface and the upper surface of the substrate is larger than an interval (distance) between a part (stepped surface) extending along a long side of the housing in the stepped surface and the upper surface of the substrate.

On the assumption that a pair of hanging parts is provided in a lead frame and a clip includes a main body part and a pair of extension parts, the pair of the extension parts is mounted and supported on the pair of the hanging parts. Accordingly, the clip is mounted on a lead (one point) and the pair of the hanging parts (two points), and the clip is supported by the three points.

Semiconductor device and manufacturing method thereof

Each of first and second semiconductor devices mounted on a substrate includes an emitter terminal electrically connected with a front surface electrode of a semiconductor chip and exposed from a main surface of a sealing body located on a front surface side of the semiconductor chip. Each of the first and second semiconductor devices includes a collector terminal electrically connected with a back surface electrode of the semiconductor chip and exposed from the main surface of the sealing body located on a back surface side of the semiconductor chip. The collector terminal of the first semiconductor device is electrically connected with the emitter terminal of the second semiconductor device via a conductor pattern formed on an upper surface of the substrate.

Reliability of a semiconductor device is improved. A third semiconductor chip on which a control circuit is formed, and a first semiconductor chip of a plurality of IGBT chips are electrically connected via a high-side relay board. That is, the first semiconductor chip and the third semiconductor chip are electrically connected via a first wire, a high-side relay board and a second wire. Similarly, the third semiconductor chip on which the control circuit is formed and a second semiconductor chip of a plurality of IGBT chips are electrically connected via a low-side relay board. That is, the second semiconductor chip and the third semiconductor chip are electrically connected via the first wire, the low-side relay board and the second wire.

Semiconductor module

For example, a semiconductor device has a lead connected to a second portion of a chip mounting part on which a semiconductor chip to be a heat source is mounted and a lead connected to a third portion of the chip mounting part on which the semiconductor chip to be the heat source is mounted. Further, each of the leads has a protruding portion protruding from a sealing member. In this manner, it is possible to enhance a heat dissipation characteristic of the semiconductor device.

Semiconductor device

To provide a technique that can improve the data retention characteristic of an MRAM device by improving the resistance against an external magnetic field in a semiconductor device including the MRAM device. A first magnetic shield material is disposed over a die pad via a first die attach film. Then, a semiconductor chip is mounted over the first magnetic shield material via a second die attach film. Furthermore, a second magnetic shield material is disposed over the semiconductor chip via a third die attach film. That is, the semiconductor chip is disposed so as to be sandwiched by the first magnetic shield material and the second magnetic shield material. At this time, while the planar area of the second magnetic shield material is smaller than that of the first magnetic shield material, the thickness of the second magnetic shield material is thicker than that of the first magnetic shield material.

A semiconductor device in which memory chips are stacked on the surface of a wiring substrate has a microcomputer chip and an interposer chip arranged on the surface of the memory chip. The pads of the microcomputer chip and the pads of the interposer chip are arranged almost circularly and are connected by bonding wires.

A sealing resin is provided for encapsulating the die pad, the first and second semiconductor chips and the wires so that the other surface of the die pad is exposed.
