Abstract:
1. A configuration for making contact with a semiconductor substrate, the configuration comprising: a first sealing ring; a second sealing ring being larger than said first sealing ring; a base body having a base-body surface, said first sealing ring and said second sealing ring disposed on said base-body surface, said first sealing ring being disposed completely inside a region of said base-body surface being surrounded by said second sealing ring, said base body having a first opening and a second opening formed therein each starting from said base-body surface and extending between said first sealing ring and said second sealing ring; a semiconductor substrate having a first main surface and a second main surface, said semiconductor substrate disposed on said first sealing ring and said second sealing ring with said first main surface facing said base body; a conductive layer having a surface disposed on said semiconductor substrate, said conductive layer disposed such that a current impressed into said conductive layer being uniformly distributed across said first main surface of said semiconductor substrate; a first line system connected to said first opening for admitting and discharging at least one electrically conductive liquid; a second line system connected to said second opening for admitting and discharging the electrically conductive liquid; and a contact wire disposed uncovered on said base-body surface of said base body between said first sealing ring and said second sealing ring.
