Silicon Sensor International AG (Berlin, Germany) has opened a new US subsidiary called Pacific Silicon Sensor (Westlake Village, CA). Founded in 1991 and having 39 employees, Silicon Sensor International develops and manufactures custom silicon photosensors for the detection of IR through x-ray radiation, as well as alpha, beta, and gamma radiation. The new subsidiary will manufacture PIN photodiodes, UV photodiodes, avalanche photodiodes, and photodiode arrays. It will be headed by George Pankau, formerly CEO of Centronic Inc. (Newbury Park, CA)—another maker of sensors for light and ionizing radiation.
