Microchip manufacture. Technician in clean room clothing using an ultra-high vacuum evaporation system to make microchips. He is holding a silicon wafer (gold), onto which conducting tracks will be deposited in the vacuum chamber (centre right). The large projections seen at lower left are ovens which will vaporise the mate- rial to be deposited on the wafer. Clean room clo- thing helps prevent dust from damaging the chips.
