摘要： A process of fabricating a sub-micron MOSFET device, featuring a high dielectric constant gate insulator layer, and a metal gate structure, has been developed. Processes performed at temperatures detrimental to the high dielectric, gate insulator layer, such as formation of spacers on the sides of subsequent gate structures, as well as formation of source/drain regions, are introduced prior to the formation of the high dielectric, gate insulator layer. This is accomplished via use of a dummy gate structure, comprised of silicon nitride, used as a mask to define the source/drain regions, and used as the structure in which sidewall spacers are formed on. After selective removal of the dummy gate structure, creating an opening in an interlevel dielectric layer exposing the MOSFET channel region, deposition of the high dielectric, gate insulator layer, on the surface of the MOSFET channel region, is performed.

摘要： A process for fabricating a MOSFET device, featuring a narrow lateral delta doping, or a narrow anti-punchthrough region, located in the center of the MOSFET channel region, has been developed. The process features formation of the narrow, anti-punchthrough region, via use of an ion implantation procedure, performed using an opening, comprised with sidewall spacers, as an implant mask. After formation of the narrow, anti-punchthrough region, the sidewall spacers are removed, and a gate insulator layer, and a polysilicon gate structure, are formed in the spacerless opening, defining a channel region wider than the narrow, anti-punchthrough region.

摘要： A semiconductor structure may implement a metal-oxide-metal capacitor. When layer design rules change from one layer to the next, the structure may change the direction of the interleaved plates of the capacitor. For example, when the metallization width or spacing design rules change from layer M3 to layer M4, the structure may run the capacitor traces in different directions (e.g., orthogonal to one another) on M3 as compared to M4. Among the layers that adhere to the same design rules, for example layers M1, M2, and M3, the structure may run the capacitor traces in the same direction in each of the layers M1, M2, and M3. In this way, the capacitor traces overlap to large extent without misalignment on layers that have the same design rules, and the structure avoids misalignment of the capacitor traces when the design rules change.

摘要： According to an exemplary embodiment, a power clamp for providing on-chip ESD and mistrigger event protection includes a clamping transistor coupled between a power bus and a ground. The power clamp further includes a number of inverter stages coupled in series, where a first inverter stage has an output coupled to the clamping transistor. The power clamp further includes a turn-off resistor coupled between the power bus and an input of the first inverter. The turn-off resistor is configured to cause the clamping transistor to automatically turn off after having been turned on. The turn-off resistor determines a period of time that the clamping transistor is turned on after an ESD or mistrigger event has occurred on the power bus. The power clamp further includes a timing circuit coupled to the inverter stages. The power clamp further includes a feedback transistor coupled between a second inverter stage and the power bus.
