Abstract
A new integrated circuit structure which includes two types of active devices: a first set of IGFETs has silicide gates, and the second set has TiN gates. The same TiN thin film layer also provides local interconnect. Optionally the TiN-gate devices may be used for high-voltage devices and the silicide-gate devices used for logic devices.
