OYAMA, JAPAN--(Business Wire/Korea Newswire) 06 July, 2017 -- Gigaphoton Inc., a leading manufacturer of light sources used in semiconductor lithography, has announced that the company, which is developing laser-produced plasma (LPP) light sources for EUV scanners, has confirmed the potential of over 80% availability with a pilot light source Note)that assumed operation in leading-edge semiconductor mass-production lines. This availability level enables mass-production.

This spring, Gigaphoton conducted a simulation test for two weeks with a system equipped with a dummy collector mirror using the EUV pilot light source currently under development and testing, and achieved 64% availability. The operating states of the pilot light source consisted of 64% for the operating & waiting time, 25% for the down time on holidays, at night, etc., and 11% for the down time for maintenance, etc. This is potentially equivalent to availability of 80% or higher if the light source had been operating without stopping on holidays, at night, etc.

Hakaru Mizoguchi, Vice President & CTO of Gigaphoton said, “The potential of over 80% availability was confirmed with a pilot source that assumed operation in leading-edge semiconductor mass-production lines, indicating that we have come closer to introducing EUV light sources to the market. We will continue to develop EUV light sources that achieve high availability and reliability to enable mass-production.”

Note) Light source designed by Gigaphoton for use in EUV lithography mass-production factories. Also called high output demonstration equipment.
*This project accesses the experimental results of a subsidy program under New Energy and Industrial Technology Development Organization (NEDO).
