Fujitsu Ltd has begun manufacture of Gallium Arsenide chips for use in its own supercomputers. In 1991 Fujitsu completed its first GaAs plant, but it appears to be running at well below capacity according to a the Nikkei Industrial Daily, because demand is low. Gallium Arsenide chips are used in Fujitsu’s VPP500 series of vector parallel processors, which packs arrays up to 222 of the GaAs chips. The first VPP500 machine was ordered by the Aachen Technical University (CI No 2,197) in Germany, the second by Japan’s Space Research Institute, a body under the aegis of the Education Ministry.
