Radiation tolerant silicon nitride insulated gate field effect transistors

Metal-Insulated-Semiconductor Field Effect Transistor /MISFET/ device uses a silicon nitride passivation layer over a thin silicon oxide layer to enhance the radiation tolerance. It is useful in electronic systems exposed to space radiation environment or the effects of nuclear weapons.

Modification to improve self-isolating transistor arrays

Fabrication process improves the size ratio and shape factor of the base region of self-isolating transistor arrays. Basic processing steps in the modified method include, sub-diffusion, epitaxial layer growth, isolation-diffusions, enhancement diffusions, aluminum interconnect deposition, and testing and packaging.

Lateral PNP bipolar transistor with aiding field diffusions

Fabrication technique produces field aided lateral PNP transistors compatible with micropower switching circuits. The sub-collector diffusion is performed with phosphorus as the dopant and the epitaxy is grown using the higher temperature silicon tetrachloride process.
