A silicon crystal being grown by the Czochralski process at the Raytheon Corp. semiconductor plant in Newton, Massachusetts, USA, in 1956 for use in the first silicon transistors. The transistor was invented in 1946, and the Czochralski process was first used to grow silicon crystals to make the first silicon transistors at Bell Labs in 1953, so this is one of the earliest silicon crystal production plants.
