Semiconductor Clean Room

The cleanroom has the essential equipment needed to create semiconductor devices such as light emitters and receivers from novel wafer structures.

Electrical connections are made with gold wires thinner than a human hair using wirebonders and other bonding techniques used by worldwide semiconductor manufacturers.

The devices made in the facility may have etched features with dimensions smaller than a micrometre. Thin film contacts and waveguides for the devices are deposited by a vacuum coating system.

The contact metals (gold and dopants like germanium, tin, magnesium and zinc) are annealed to make the ohmic and Schottky contacts needed for devices like MESFETs.
