Formulating high sensitivity and high resolution EUV Resists is a critical issue gating the adoption of EUV lithography. The ability of resist manufacturers to quickly screen outgassing rates and sensitivity of EUV resists will facilitate faster formulation of a production-ready EUV photoresist. The high power and low cost per watt of the Energetiq EQ-10 light source enables relatively simple designs without complex optics to deliver relevant data efficiently. Because the source operates without electrodes, a significant source of contamination is removed, further simplifying the design of exposure systems.Data will be presented from two prototype exposure systems. The first, in operation at Osaka University, Japan 1 has been used for in-band flood exposure experiments to test resist sensitivity and develop photochemical modeling capability. The second, in operation at SUNY-Albany, 2 integrates exposure/sensitivity with outgassing measurements (GC/MS and RGA) and also allows direct tests of mirror contamination, at power densities near those required for Beta exposure tools. Features of both experiments have been integrated into a commercial device. Details of this tool -the Litho Tech Japan EUVES-7000 system for resist outgassing and exposure -will be presented at this meeting. 3

Small spherical samples (diameter approximately 2 mm) of NdBa 2 Cu 3 O 7−␦ (Nd123) were fully melted in Ar gas flow in an aero-acoustic levitation device and subsequently rapidly cooled by splat quenching. For samples quenched above the liquidus, the microstructual and x-ray-diffraction (XRD) observations suggested the existence of the amorphous phase with small quantities of the BaCuO 2 and BaCu 2 O x . The high-temperature XRD results indicated that the decomposition of the amorphous phase, probably assisted by atmospheric CO 2 and H 2 O, led to formation of the BaCO 3 phase at 400°C and, subsequently, the Nd123 phase was formed by the solid diffusion above 800°C. Another set of Nd123 samples was fully melted in O 2 gas flow, undercooled while levitated, and then splat quenched at a temperature below the peritectic temperature (T P ). These samples possessed a microcrystalline microstructure of the Nd123 phase that was confirmed by XRD. This indicated that the Nd123 phase was solidified directly from the undercooled melt quenched below T P .
