Also, because this IGBT is a voltage-driven type and easy to handle, the demand for the market is increasing toward larger capacities, and along with the increase in the size of semiconductor chips, there is a trend toward larger capacities. In order to increase the number of modules, a module structure in which a plurality of IGBTs are incorporated in the same package is often adopted.

In an insulated gate element (MOS control device) such as an IGBT, an emitter electrode as a main electrode and a gate electrode as a control electrode are formed side by side on one main surface of a semiconductor chip. Therefore IG
When assembling the BT chip by packaging, the collector on the second main surface side can be directly mounted on the metal base that also serves as a radiator, but the emitter electrode and gate electrode on the first main surface side can be externally mounted separately. It is necessary to pull it out through the lead-out terminal. So, in the conventional package assembly structure,
An external lead terminal for the emitter and the gate is provided on the upper surface side of the package case together with the above-mentioned metal base, and an aluminum conductor wire having a wire diameter of about 300 μm is wired between the emitter electrode and the external lead terminal and between the gate electrode and the external lead terminal. I try to bond it and pull it out.

By the way, in the above-mentioned conventional assembly structure, although sufficient heat can be dissipated from the collector side, heat is hardly dissipated from the emitter side, so that the current capacity is significantly limited. It Also, in a large current element, the number of bonding wires connected to the emitter electrode also increases. Especially, in the configuration in which a plurality of IGBTs are incorporated in the same package to form a module, the number of wires reaches several hundreds. Is increased, which causes a problem that a large surge occurs during the switching operation of the IGBT.

On the other hand, in order to solve the problems of heat dissipation and wiring inductance by the above-mentioned assembly structure, the IGBT is built in the flat package and formed on the main surface thereof, like the conventional pressure contact type semiconductor device. It is conceivable that the collector electrode and the emitter electrode are respectively brought into surface contact with the upper and lower electrode plates provided on the package side to be drawn out. However, in the IGBT, if the package-side electrode plate is brought into pressure contact with the emitter electrode on the insulating layer covering the gate electrode, this pressure may also be applied to the gate electrode and destroy the gate electrode structure. A flat element is constructed by avoiding the gate electrode portion and providing a portion called a collecting electrode having both heat dissipation and current passage and pressurizing the portion. Also, as the IGBT module, if a pressure contact type flat package is adopted in a composite device in which an IGBT and a flywheel diode attached thereto are incorporated in the same package,
The following problems arise. That is, since the IGBT and the flywheel diode, which are required in terms of electrical characteristics, generally have different chip height dimensions (wafer thickness), different semiconductor chips having different height dimensions are arranged side by side. Then, when the chips are assembled in the same flat package, the heights of the upper surfaces of the chips are not uniform, and it becomes extremely difficult to uniformly press and contact each semiconductor chip. To prevent this, a solder sheet is used to fix the semiconductor chip to the electrode plate of the flat package so as to absorb the height difference.

However, a carbon positioning jig is used for positioning the solder sheet and the semiconductor chip, soldering is performed, and then the jig is removed. Instead, a fluororesin assembly guide is used. Is used for positioning so that the collector electrode of the semiconductor chip and the convex part of the electrode plate of the flat package are in contact, but there is a dimensional tolerance between the carbon jig and the fluororesin assembly guide. However, there still remains a problem that the convex portions of (1) do not fit accurately and the convex portions press the gate electrode to destroy the semiconductor chip.

As described above, the common electrode plate on the package side with respect to the current collecting electrode portion provided in the area other than the gate electrode and having the heat dissipation for each of the plurality of semiconductor chips incorporated in the flat package is provided. No pressure is applied to the gate electrode part of the semiconductor chip by making pressure contact through each contact terminal body that has surface contact with the (emitter side) and secures parallelism and the same height. In addition, heat is efficiently radiated from the first main surface on the emitter side through the common electrode plate exposed on the outer surfaces of the contact terminal body and the package. As a result, heat dissipation from the second main surface side on the collector side is dramatically improved, and the current capacity of the semiconductor device can be increased. Moreover, since the bonding wire is not used for connecting the main electrodes, the internal inductance is also reduced.

According to the present invention, a plurality of semiconductor chips can be placed in a flat package in a flat package so that a uniform pressure contact can be achieved by surface contact without applying an undue pressing force to the gate electrodes of the semiconductor chips. Assembled, allowing heat to be dissipated from both sides of each semiconductor chip to increase the current capacity, and because the bonding wire is not used to draw out the current from the main electrode, the internal wiring inductance is also reduced, and the flat package has a hermetically sealed structure. In combination with this, the reliability of the semiconductor device can be greatly improved. In addition, the assembly guide ensures accurate positioning between the element and the contact terminal body, and pressure applied to the gate electrode portion due to displacement or the like is eliminated so that the gate electrode portion is not damaged. It can also be used in the element manufacturing process,
Compared to the case where a carbon jig is used for positioning during soldering and fluorocarbon resin is used for positioning during product manufacturing, the number of steps can be greatly reduced.
