Abstract: Use of a forward biased diode to reduce leakage current of transistors implemented on silicon on insulator (SOI) is a particular challenge due to the difficulty of achieving effective contact with the region beneath the gate of the transistor. An improved implementation in SOI gate fingers that reach under the source through tunnels that are contacted with a region outside the transistor. A further embodiment uses drain extension implants to provide good channel connection.

Abstract: A semiconductor device that includes transmitter circuits and receiver circuits that share a common data line and method is disclosed. Each transmitter circuit may include a frequency modulator that receives a stream of data and provides a frequency modulated data output at a predetermined carrier frequency. Each receiver may include a band pass filter that allows a corresponding frequency modulated data output from a corresponding transmitter circuit to pass through to a demodulator while essentially excluding the other frequency modulated data. In this way, a plurality of transmitter circuits can simultaneously transmit data with each one of the plurality of transmitter circuits transmitting data to a predetermined receiver circuit.

Abstract: In deep submicron memory arrays there is noted a relatively steady on current value and, therefore, threshold values of the transistors comprising the memory cell are reduced. This, in turn, results in an increase in the leakage current of the memory cell. With the use of an ever increasing number of memory cells leakage current must be controlled. A method of manufacture of a dynamic threshold voltage control scheme implemented with no more than minor changes to the existing MOS process technology is disclosed. The disclosed invention controls the threshold voltage of MOS transistors. Methods for enhancing the impact of the dynamic threshold control technology using this apparatus are also included. The invention is particularly useful for SRAM, DRAM, and NVM devices.

Abstract: An apparatus and method for manufacturing metal-oxide semiconductor (MOS) transistors that are operable at voltages below 1.5V, which MOS transistors are area efficient, and where the drive strength and leakage current of the MOS transistors is improved. The invention uses a dynamic threshold voltage control scheme that does not require a change to the existing MOS technology process. The invention provides a technique that controls the threshold voltage of the transistor. In the OFF state, the threshold voltage of the transistor is set high, keeping the transistor leakage to a small value. In the ON state, the threshold voltage is set to a low value, resulting in increased drive strength. The invention is particularly useful in MOS technology for both bulk and silicon on insulator (SOI) CMOS.

Abstract: An apparatus and method of manufacture for metal-oxide semiconductor (MOS) transistors is disclosed. Devices in accordance with the invention are operable at voltages below 2V. The devices are area efficient, have improved drive strength, and have reduced leakage current. A dynamic threshold voltage control scheme comprised of a forward biased diode in parallel with a capacitor is used, implemented without changing the existing MOS technology process. This scheme controls the threshold voltage of each transistor. In the OFF state, the magnitude of the threshold voltage of the transistor increases, keeping the transistor leakage to a minimum. In the ON state, the magnitude of the threshold voltage decreases, resulting in increased drive strength. The invention is particularly useful in MOS technology for both bulk and silicon on insulator (SOI) CMOS. The use of reverse biasing of the well, in conjunction with the above construct to further decrease leakage in a MOS transistor, is also shown.
