Abstract: FET designs that exhibit low leakage in the presence of the edge transistor phenomenon. Embodiments includes nFET designs in which the work function ?MF of the gate structure overlying the edge transistors of the nFET is increased by forming extra P+ implant regions within at least a portion of the gate structure, thereby increasing the Vt of the edge transistors to a level that may exceed the Vt of the central conduction channel of the nFET. In some embodiments, the gate structure of the nFET is modified to increase or “flare” the effective channel length of the edge transistors relative to the length of the central conduction channel of the FET. Other methods of changing the work function ?MF of the gate structure overlying the edge transistors are also disclosed. The methods may be adapted to fabricating pFETs by reversing or substituting material types.

Abstract: Methods and structures for mitigating back gate effects in high voltage and low voltage semiconductor devices of a same integrated circuit fabricated in a silicon-on-insulator technology are described. According to one aspect, one or more resistive couplings are used to control surface potentials at regions of a substrate used for the SOI fabrication proximate the high voltage and low voltage semiconductor devices. According to another aspect, an N-type implant that is biased through a resistive coupling is used to provide a high potential differential with respect to a substrate potential.

Abstract: Modified silicon-on-insulator (SOI) substrates having a trap rich layer, and methods for making such modifications. The modified regions eliminate or manage accumulated charge that would otherwise arise because of the interaction of the underlying trap rich layer and active layer devices undergoing transient changes of state, thereby eliminating or mitigating the effects of such accumulated charge on non-RF integrated circuitry fabricated on such substrates. Embodiments retain the beneficial characteristics of SOI substrates with a trap rich layer for RF circuitry requiring high linearity, such as RF switches, while avoiding the problems of a trap rich layer for circuitry that is sensitive to accumulated charge effects caused by the presence of the trap rich layer, such as non-RF analog circuitry and amplifiers (including power amplifiers and low noise amplifiers).

Abstract: Integrated circuits (ICs) that avoid or mitigate creation of changes in accumulated charge in a silicon-on-insulator (SOI) substrate, particularly an SOI substrate having a trap rich layer. In one embodiment, a FET is configured such that, in a standby mode, the FET is turned OFF while maintaining essentially the same VDS as during an active mode. In another embodiment, a FET is configured such that, in a standby mode, current flow through the FET is interrupted while maintaining essentially the same VGS as during the active mode. In another embodiment, a FET is configured such that, in a standby mode, the FET is switched into a very low current state (a “trickle current” state) that keeps both VGS and VDS close to their respective active mode operational voltages. Optionally, S-contacts may be formed in an IC substrate to create protected areas that encompass FETs that are sensitive to accumulated charge effects.
