EMF was established to develop, manufacture and market technologically advanced equipment called Metal Organic Chemical Vapour Deposition (MOCVD) machines.  MOCVD machines are used to deposit very thin layers of chemicals on wafer substrates, which are then used to make high brightness LEDs and other devices such as solar cells, laser diodes, VCSEL lasers and other photonic devices.  Some of these technologies are used in traffic signals and mobile phone back-lighting. EMF has developed proprietary technology which represents a major advance in MOCVD manufacturing technology which allows manufacturers to significantly increase their yield of wafers.
