Demetallisation: electrodes for a prototype electrical device are produced simply by using a focussed laser beam to remove gold film from a glass substrate. The gold film is less than a micron in thickness. The path which the laser follows is derived from a CAD package allowing rapid changes to the design to be made and implemented. Such a process can produce dozens of devices in a few minutes allowing for the evaluation and selection of the desired devices. This method is also useful for producing small numbers of prototype devices for testing. This serial process can be sow however for very large and complex patterns but it may still be more flexible and cost-effective than making prototypes by other 'conventional' etching routes.
