  • Publication number: 20180358352
    Abstract: A device and structure for providing electrostatic discharge (ESD) protection. Schottky barrier diode (SBD) structure comprising a substrate of a first dopant polarity, a well region of a second dopant polarity formed on or within said substrate, an anode region of a first dopant polarity, a cathode of a second polarity, and a rectifying contact on said anode and/or said cathode, wherein said rectifying contact is formed substantially near the surface of said substrate to provide a rectifying barrier junction between the conducting layer and the semiconductor substrate, providing electrical coupling in said Schottky Barrier diode structure. The disclosure further includes SOI Schottky Barrier polysilicon-bound diodes (also known as Lubistor structures). Additionally, a diode configured SOI dynamic threshold MOSFET with rectifying barrier junctions on the drain or source region.

  • Patent number: 8946013
    Abstract: A disposable structure displaced from an edge of a gate electrode and a drain region aligned to the disposable structure is formed. Thus, the drain region is self-aligned to the edge of the gate electrode. The disposable structure may be a disposable spacer, or alternately, the disposable structure may be formed simultaneously with, and comprise the same material as, a gate electrode. After formation of the drain regions, the disposable structure is removed. The self-alignment of the drain region to the edge of the gate electrode provides a substantially constant drift distance that is independent of any overlay variation of lithographic processes.
