Overview

The NSR-2005i10C is a stepper that uses an I-line light source with a wavelength of 365 nanometers. It achieves a resolution of 0.45 micron or better over a wide exposure area of 22mm x 22mm to 17.9mm x 25.2mm. With an optional feature called Shrine (Super High Resolution by Illumination Control), the resolution can be improved to 0.35 micron or better. This stepper is capable of mass-producing 16Mbit DRAMs at its normal resolution of 0.45 micron.
