Project Accountant jobs in United Kingdom

Infinitesima was spun out of the University of Bristol in 2001 and has been developing innovative metrology solutions which improve speed and precision in the manufacture of semiconductors. The company’s technology combines the 3-dimensional surface detection capability of atomic force microscopy (AFM), with high-speed laser activation and the accuracy of interferometry. The Rapid Probe Microscope (RPM™) is protected by an extensive patent portfolio. The company’s RPM™ technology is being used by leading semiconductor equipment companies globally. Semiconductor devices provide the foundations on which progress in the technology sector are enabled.
