The invention of semiconductor technology by U.S. scientists led to the birth of Silicon Valley in the 1950s, which helped the U.S. became the dominant force in semiconductor research and manufacturing, but that dominance has been slipping for decades. Only 12 percent of semiconductor chips are produced in the U.S. today, down from 37 percent in 1990, according to the Semiconductor Industry Association.

Feel free to reply to any comment by clicking the "Reply" button.Bell labs and a man called William Shockley were early innovators during the late 1940s. However, the pioneer of germanium diodes in electronic devices was a German, Ferdinand Braun (1850 –1918), who discovered the semiconductor diode in 1874. Then in 1901, Jagadis Chandra Bose, a professor of physics in Calcutta, India, filed a U.S patent for a galena crystal point-contact semiconductor diode for detecting radio signals.
So as you can see, semiconductor technology was NOT an American invention.
However, the USA did provide a home for innovators.
