Integrated chip. Coloured Scanning Electron Micro- graph (SEM) of the surface of a high-performance microprocessor computer chip. Rows of electronic elements make up this part of the integrated circuit. The elements have been imprinted by various deposition and etching processes, onto the surface of a semicondutor material such as silicon. Magnification: x730 at 6x7cm size. x1,150 at 4x5ins
