Abstract
A function test is implemented for an individual circuit level (1) that is provided for vertical integration in a semiconductor component. Stacks of circuit levels respectively provided over or under this circuit level in the finished component are simulated as test heads (2, 3). These test heads are provided with terminal contacts for reversible contacting. The circuit level (1) under test is connected to these test heads (2, 3) during the function test, and the test heads are removed after the test.
