Assignee: X-FAB SEMICONDUCTOR FOUNDRIES GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method for producing a semiconductor device comprising:
providing a layout of a trench isolation structure (10, 10′) that electrically isolates a first active component region from a second active region (20, 22);
in addition to an isolation trench base wall (30) extending a direction of extension of the trench isolation structure (10, 10′), enlarging or extending an entire electrically conductive sidewall of the trench isolation structure by providing isolation trench portions (32a; 32b; 30c, 30d) with electrically conductive sidewall portions (14a, 14b, 14c″); and
producing the semiconductor device by using the layout.
