Immersion scanner ultrapure water
Witryna1 lut 2010 · Immersion lithography [ 1 - 4] has changed the way we view defectivity issues at the wafer edge significantly. During the immersion exposure sequence, the wafer edge is in contact with the water from the immersion hood (IH), introducing additional concerns beyond direct contact of resist with the scanner. First, when the … Witryna24 maj 2006 · In this paper we describe the design and development of point-of-use UPW (ultra pure water) components and systems for the immersion application.

WitrynaSurprisingly, ultra-pure water (H20) may be the magic solution to be used as the immersion fluid. Water has absorption values below 0.50 cnf’ ~ l85nm and below 0.05 cm at l93nm In other words, at l93mn wavelength the absorption is below 5% at working distances of up to 6mm [1]. The refractive index of water is 1.437 which will effectively ... WitrynaLarge amounts of UPW are consumed in all fabs - according to the International Technology Roadmap for Semiconductors (ITRS) (2011), device fabs utilized 7 liters/cm 2 of UPW per wafer out. This means that a typical 200 mm wafer fab that processes 20,000 wafers per month can use up to 3,000 m 3 of UPW per day. That is the …
