Abstract
A process for producing a semiconductor device comprises the following process steps: provision of a semiconductor substrate (); formation of a functional layer () on a semiconductor surface () of the semiconductor substrate (); and production of at least one doped section () on the semiconductor surface () by driving a dopant into the semiconductor substrate () from the functional layer (). The functional layer () is formed in such a way that it passivates the semiconductor surface (), acting as a passivation layer upon completion of the semiconductor device.
