An electrostatic discharge protection device including a gate electrode formed on a substrate. First and second diffusion regions of a first conductivity type are formed in the substrate with the gate electrode located in between. A first silicide layer is formed in the first diffusion region. A silicide block region is formed between the gate electrode and the first suicide layer. A third diffusion region is formed below the first silicide layer to partially overlap the first diffusion region. The third diffusion region and first silicide layer have substantially the same shapes and dimensions. The third diffusion region and a portion below the gate electrode located at the same depth as the third diffusion region contain impurities of a second conductivity type. The third diffusion region has an impurity concentration that is higher than that of the portion below the gate electrode.

Silicidation of a polysilicon line having frcc upper sidewalls is performed so that no stress is applied to the sidewalls of the polysilicon line, resulting in the formation of a reduced stress silicide structure. This is accomplished by forming a polysilicon line having spacers on either side which extend above the upper surface of the polysilicon line but which are spaced from the edge of the polysilicon line. A layer of a metal such as titanium or tungsten is provided in contact with the top surface polysilicon line. The structure is annealed to cause the metal to react with the polysilicon to form a layer of silicide. Since the upper side portions of the polysilicon line are spaced away from the spacers during the silicidation anneal, the growing silicide region has room to expand without being subjected to lateral stresses in the silicidation process. The suicide is formed in a reduced stress condition, as compared to conventional processes, so that the silicide layer produced will be more readily converted to the desired low resistivity phase of silicide.

A method of preventing an inmate from committing suicide is disclosed wherein an oximeter having an RF transmitter associated therewith is mounted on a bracelet which is locked onto the inmate's wrist or ankle. The RF transmitter transmits data collected by the oximeter and furnishes the same to a control station monitor including an RF receiver. Should the oximeter sense that the oxygen saturation level of the inmate has dropped to a predetermined level, an alarm is automatically activated to enable personnel to rush to the inmate's cell or room. If the oximeter is a pulse oximeter, pulse rate data will also be transmitted to the central station so that the alarm will be activated should the pulse rate of the inmate drop to a predetermined level.

Methods are presented for fabricating transistor gate structures, wherein upper and lower metal suicides are formed above a gate dielectric. In one example, the lower silicide is formed by depositing a thin first silicon-containing material over the gate dielectric, which is implanted and then reacted with a first metal by annealing to form the lower silicide. A capping layer can be formed over the first metal prior to annealing, to prevent oxidation of the metal prior to silicidation, and a barrier layer can be formed over the lower silicide to prevent reaction with subsequently formed silicon material. In another example, the lower silicide is a multilayer silicide structure including a plurality of metal silicide sublayers.

A suicide cap structure and method of fabricating a suicide cap having a low sheet resistance. The method provides a semiconductor substrate and a MOSFET structure comprising a gate insulator on the substrate, an Si-containing gate electrode on the gate insulator layer, and source/drain diffusions.

Described is a MOS gate-controlled SCR (UGSCR) structure with a U-shaped gate (UMOS) for an ESD protection circuit in an IC device which is compatible with shallow trench isolation (STI) and self-aligned suicide (salicide) fabrication technology. The UMOS gate is located in a p-substrate and is surrounded by an n-well on either side. Adjacent to one side of the UMOS gate, a first n+ diffusion is formed which straddles the first n-well. The n+ diffusion together with a p+ pickup diffused next to it form the cathode of the SCR (thyristor). Adjacent to the other side of the UMOS gate, a second n+ and p+ diffusion are formed in a second n-well. The second n+ and p+ diffusion together with the UMOS gate form the anode of the SCR and the input terminal of the circuit to be protected. The SCR is formed by the first n+ diffusion/n-well (cathode), the p-substrate, the second n-well and the second p+ /n+diffusion (anode). A latchup immune circuit is achieved by creating a U-shaped gate structure which is lined with a thick gate oxide--similar to a field oxide--under the poly gate.
