The concept of measuring or moving with sub-nanometric accuracy was once considered unattainable. Today, Queensgate Instruments advanced NanoSensor and NanoPositioning technology has turned this concept into reality.
The ability to move or measure with sub-nanometre precision is essential in the production of some of the most advanced products in use today. For example, wafer steppers use this nanopositioning and sensing technology in the fabrication of semiconductors, to make devices with line widths down to 90 nm; Scanning Probe Microscopes utilise nanopositioners to establish how well such chips are made; and hard disk drive heads must now be tested to nanometric accuracy as track densities increase to values thought impossible only a few years ago. These machines, and the machines which make these machines, combine advanced design with Queensgate motion control technology to position components to accuracies of a nanometre or below.
Piezo electric devices have the potential to meet the resolution requirements. However, because piezo electric devices are non-linear and exhibit hysteresis, a sensor must be used to monitor and control their position. The Capacitance sensor is ideally suited to this task, being small and with sub-atomic resolution capability. To design a NanoMechanism involves combining the piezoelectric actuator and capacitance position sensor with flexure hinges and mechanical amplifiers in such a way to produce a device capable of making pure orthogonal motions with sub nanometre precision.
