A compact, reliable, efficient and inexpensive crycooler requiring less than 1kW of power for 2W of colling at 10K will be developed and demonstrated. This performance is at least twice as efficient as the best current state-of-the-art for smalllow-temperature crycoolers. The proposed technical approach, whose feasibility has been investigated and confirmed in Phase I of this project, is to appl ...

One of the primary processes used for device patterning in the electronics industry is deep ultaviolet photolithography. However, the highly reflective substrates require reduction of this reflectivity to minimize standing waves and to maintain tightdimensional control. Most of te industry uses anti-reflective coatings (ARCs) which are applied using the spin coating technique. Unfortunately, spi ...
