Quantiscript Inc. is a nanotechnology company developing process
solutions aimed at next generation lithography (NGL) for the
microelectronics industry using proprietary NON SPIN-COATED EB
RESISTS. One of the main challenges for the industry in meeting the
lithography milestones set by the International Technology Roadmap for
Semiconductors over the next five years is the fabrication of lithography                                                              Evaporated resists                     Enabling advantages of QSR resist
