Photolithography

The Heidelberg direct writer features

The Cleanroom at LCN on the Bloomsbury site has 255 square metres of ISO 14644-1 Class 6 (Class 1000) cleanroom housing most of our equipment for Plasma etch, Photolithography, Wet Chemical, Metallisation, Furnace, Characterisation and Electron Beam Lithography processes.

Spin Coater with chucks for samples from 3x3mm up 150mm diameter, Dehydration oven and two hotplates are located in Bench 1.  This set up is for spin coating all materials that are exposed using Ultra-Violet light.

This is a Plasma etcher in a barrel configuration.  It is used primariliy for removing organic materials in an Oxygen plasma, such as photoresist.  It is an effective technique for cleaning up the residues of photoresist that remain after the Photolithography and develop processes before samples
