Abstract
An integrated circuit structure has a number of device areas each of which is configurable in a subsequent customizing process as a field effect transistor, a bipolar transistor or as a pair of those devices. Configuration of the structure is determined by correspondingly selective etching of a polysilicon layer disposed on the structure.
