Semiconductor Switching Module
First Claim
1. A semiconductor switching module, comprising:
- a power semiconductor element embodied in planar technology and including a base layer, a copper layer, at least one power semiconductor chip fitted on the copper layer, and a further electrically conductive layer, which covers at least one load terminal of the power semiconductor chip; and
means for reliably connecting the load terminal to a load circuit to be switched, the means including at least one contact device and at least one prestress device, the at least one prestress device being formed such that the at least one contact device presses with a contact area areally onto the further electrically conductive layer,and the contact area including an area form corresponding to an area form of the load terminal.

Abstract
A semiconductor switching module includes a power semiconductor element that is embodied in planar technology. In at least one embodiment, the power semiconductor element is provided with a base layer, a copper layer, and at least one power semiconductor chip that is mounted on the copper layer, and another electrically conducting layer which covers at least one load terminal of the power semiconductor chip. According to at least one embodiment of the invention, devices are provided for safely connecting the load terminal to a load circuit. The devices are configured such that a contact area thereof presses in a planar manner onto the electrically conducting layer.
