More info at http://www.pi-usa.us // Moore's law forces semiconductor manufacturers to increase the density of transistors on their circuits continuously.  This requires smaller and smaller feature sizes, down to nanometers.  The semiconductor industry is basically the first large scale industry to adapt nanotechnology.  Piezo motion technology with its unlimited positioning resolution and very fast response and high speed enables the designers of next generation semiconductor tools to keep up with Moore's law.  PI provides a very broad toolkit of piezo technology (Actuators, Motors & Nanopositioning Stages) for use in wafer positioning, Interferometry, CD Measurement, Reticle / Mask Alignment as well as  precision autiomation applications. Silicon photonics - the integration of photonics circuits on silicon wafers is the next big step and PI's automated photonics alignment systems are available to improve throughput and performance.
