Abstract: In a semiconductor device, a layer of nitrogen doped polysilicon is applied to a gate oxide in turn provided on a semiconductor body, and then a silicide film is applied to the polysilicon layer. The nitrogen in the polysilicon layer inhibits growth of native oxide on the polysilicon layer prior to the application of silicide, and at subsequent high temperature processing steps, so that the problem of the silicide layer lifting from the polysilicon layer due to this native oxide growth is avoided during subsequent high temperature processing of the device.

Abstract: A method and system for providing a semiconductor device with device isolation and leakage current control which entails processing a semiconductor substrate to form a semiconductor circuit, and providing at least one high energy implant on the semiconductor circuit is disclosed. The high energy implant is provided at an angle to source and drain regions of the semiconductor circuit so as to allow a dosage from the at least one high energy implant below and away from the surface of the active device region. In so doing, a profile is provided in which dopant distribution is substantially uniform. Therefore, the breakdown characteristics are increased and the junction capacitance of the device is reduced. Accordingly, a device manufactured in accordance with the present invention has significant advantages over devices manufactured in accordance with conventional processes.
