摘要： A method and apparatus are provided for implementing enhanced silicon-on-insulator (SOI) passgate operations. The apparatus for implementing enhanced silicon-on-insulator (SOI) passgate operations includes a silicon-on-insulator (SOI) passgate field effect transistor. A select input is coupled to the silicon-on-insulator (SOI) passgate field effect transistor. A discharging field effect transistor of an opposite channel type is coupled to the silicon-on-insulator (SOI) passgate field effect transistor. The discharging field effect transistor is activated during an off cycle of the silicon-on-insulator (SOI) passgate field effect transistor. The discharging field effect transistor is coupled to the body of the SOI passgate field effect transistor. The discharging field effect transistor is deactivated during an on cycle of the SOI passgate field effect transistor, whereby the body of the SOI passgate field effect transistor floats during the on cycle. The method for implementing enhanced silicon-on-insulator (SOI) passgate operations can be used with N-channel or P-channel implementations as well as with a combination of N-channel and P-channel devices.

摘要： A ring oscillator has an odd number of NOR-gates greater than or equal to three, each with first and second input terminals, a voltage supply terminal, and an output terminal. The first input terminals of all the NOR-gates are interconnected, and each of the NOR-gates has its output terminal connected to the second input terminal of an immediately adjacent one of the NOR-gates. During a stress mode, a voltage supply and control block applies a stress enable signal to the interconnected first input terminals, and an increased supply voltage to the voltage supply terminals. During a measurement mode, this block grounds the interconnected first input terminals, and applies a normal supply voltage to the voltage supply terminals. Also included are an analogous NAND-gate based circuit, a circuit combining the NAND- and NOR-aspects, a circuit with a ring oscillator where the inverters may be coupled directly or through inverting paths, and circuits for measuring the bias temperature instability effect in pass gates.

摘要： In a method and apparatus for reducing parasitic bipolar current in an insulated body, field effect transistor (“FET”), for an n-type FET, the body of the insulated body NFET is electrically isolated, responsive to turning on the NFET. This permits a charge to accumulate on the body in connection with turning the NFET on, temporarily lowering the threshold voltage for the insulated body NFET. Responsive to turning off the insulated body NFET, at least a portion of the charge on the body is discharged. This discharging of the body reduces parasitic bipolar current which would otherwise occur upon turning the NFET back on if the body had charged up during the time when the NFET was off. For a p-type FET that is susceptible to parasitic bipolar current, the body is discharged responsive to turning off the PFET, and isolated responsive to turning on the PFET.

摘要： This invention relates to a bipolar transistor which incorporates, in a raised base regime, an emitter, collector pedestal and intrinsic and extrinsic bases all of which are self-aligned. The invention also relates to a process for fabricating such devices which obtains the self-alignment of the above mentioned elements using a single lithographic and masking step. The structure of the transistor, in addition to having the self-aligned elements, incorporates a composite dielectric isolation layer which not only permits the carrying out of a number of functions during device fabrication but also provides for desired electrical characteristics during device operation. The composite isolation layer consists of an oxide layer adjacent the semiconductor surface; a nitride layer on the oxide layer and an oxide layer on the nitride layer in the final structure of the device. The last mentioned oxide layer starts out early in the fabrication process as a layer of oxidizable material, preferable polycrystalline silicon, which, at later steps in the process, acts as an etch-stop in its unoxidized state and as a memory element and mask in its oxidized state when a self-aligned datum element is removed and the thus exposed underlying dielectric elements must be removed to provide a planar emitter opening. The resulting transistor includes a planar emitter-emitter contact interface which provides for fine control of emitter depth in the underlying intrinsic base region.
