Abstract: An junction field effect transistor (JFET) is fashioned with a patterned layer of silicide block (SBLK) material utilized in forming gate, source and drain regions. Utilizing the silicide block in this manner helps to reduce low-frequency (flicker) noise associated with the JFET by suppressing the impact of surface states, among other things.

Abstract: High voltage bipolar transistors built with a BiCMOS process sequence exhibit reduced gain at high current densities due to the Kirk effect. Threshold current density for the onset of the Kirk effect is reduced by the lower doping density required for high voltage operation. The widened base region at high collector current densities due to the Kirk effect extends laterally into a region with a high density of recombination sites, resulting in an increase in base current and drop in the gain. The instant invention provides a bipolar transistor in an IC with an extended unsilicided base extrinsic region in a configuration that does not significantly increase a base-emitter capacitance. Lateral extension of the base extrinsic region may be accomplished using a silicide block layer, or an extended region of the emitter-base dielectric layer. A method of fabricating an IC with the inventive bipolar transistor is also disclosed.

Abstract: The disclosure herein pertains to fashioning an n channel junction field effect transistor (NJFET) and/or a p channel junction field effect transistor (PJFET) with an open drain, where the open drain allows the transistors to operate at higher voltages before experiencing gate leakage current. The open drain allows the voltage to be increased several fold without increasing the size of the transistors. Opening the drain essentially spreads equipotential lines of respective electric fields developed at the drains of the devices so that the local electric fields, and hence the impact ionization rates are reduced to redirect current below the surface of the transistors.

The dummy moat areas comprise dummy window structures having geometrical dimensions and shapes similar to those of the active window structures for the base and/or emitter windows.

Abstract: Embodiments are described for programming and erasing a memory cell by utilizing a buried select line. A voltage potential may be generated between a source-drain region and the buried select line region of the memory cell to store charge in a storage region between the source-drain and buried select line regions. The generated voltage potential causes electrons to either tunnel towards the buried storage region to store electrical charge or away from the buried storage region to discharge electrical charge.
