Silicon Fen, much like Silicon Valley in the U.S. is an indicator of how many high-tech businesses and technology fledglings were created on science parks around the town. Such companies include Abcam, CSR, Acorn Computers (now ARM), CamSemi, Jagex and Sinclair. The U.S. Information Technology giant, Microsoft, has erected one of its U.K. Microsoft Research offices in a University of Cambridge technology park. Another major high-tech business to have set up shop in Cambridge is Marshall Aerospace. A lot of money has been invested here.
