Abstract

The Energetiq EQ-10 is a medium-power (10 W/2π, 13.5nm +/- 1%, Xenon) EUV source suitable for a variety of mirror testing, resist exposure, and defect inspection applications. The EQ-10 was designed to operate at a pulse frequency of 1 to 2 kHz¹. However, exposure equipment appropriate for High Volume Manufacturing (HVM) requires sources which are projected to operate at 10 kHz or greater². To minimize technical risk in infrastructure development programs now under way in support of future HVM production, scaling of various physical processes with pulse rate require investigation. A program to redesign the EQ-10 to operate at 10 kHz pulse rate has been completed. We report here on the design process and the operating characteristics of the high-frequency source.
