Hydrogen - The carrier of life

Hydrogen, and hydrogen compounds with oxygen, carbon, nitrogen, and phosphorus in construction of living systems

HYDROGEN COMPOUND↗

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.

Improved silicon solar cells

Redistribution of phosphorus within the n-type layers of n-on-p silicon solar cells results in significant improvements in cell performance. Electrical current output is increased, reduction in current output due to radiation damage is lessened, and very shallow junctions are no longer needed.
