High power laser-produced plasma source for nano-lithography

摘要

JMAR develops Laser-Produced Plasma (LPP) sources for lithography applications, and has specifically developed Collimated laser-Plasma Lithography (CPL~(TM)) as a 1 nm collimated point source and stepper system to address sub-100nm lithography needs. We describe the CPL~(TM) source development, show demonstrated sub-100nm printing capability, and describe status of a beta lithography tool. The system will be power-scaled to address silicon device contacts and vias at 90nm and below. This development has much in common with LPP Extreme UltraViolet Lithography (EUVL) sources; an EUV source concept is presented to address the high power requirements of that Next Generation Lithography (NGL).
