In a process for producing a ceramic housing (1), first of all a ceramic
base body (4) comprising a ceramic base (2) and side parts (3) is
produced. Then, a metal frame (7) is placed onto the ceramic base body
(4) and a window (11) is soldered onto a side opening (6). After a
photoactive semiconductor chip has been introduced into the ceramic base
body (4), the ceramic housing (1) is closed off using a metal cover (12).
