Paper Abstract

Gigaphoton Inc. is developing a laser produced plasma (LPP) extreme ultra violet (EUV) light source for high-volumemanufacturing (HVM) semiconductor lithography. Original technologies and key components of this source include a high-power carbon dioxide (CO2) laser with 15ns pulse duration, a short wavelength solid-state pre-pulse laser with 10ps pulse duration, a highly stabilized small droplet (DL) target, a precise laser-DL shooting control system and debris mitigation technology with a magnetic field. In this paper, an update of the development progress of the total system and of the key components is presented.
