OYAMA, JAPAN--(Business Wire / Korea Newswire) February 22, 2019 -- Gigaphoton Inc. (Head Office: Oyama, Tochigi; President & CEO: Katsumi Uranaka), a manufacturer of lasers used in semiconductor lithography, announced that Gigaphoton has started shipping the world’s highest output power class KrF laser, the G45K, in March 2019 and it will contribute to further improvements in the production efficiency of state-of-the-art memory chips.

It is said that due to the spread of the IoT and AI in recent years, the amount of information data around the world has increased tenfold over the last few years. In response to this, chip makers are working to improve the productivity of highly-integrated, state-of-the-art memory chips. In the lithography process, the output power of the KrF laser, which is used as the light source, directly contributes to productivity improvements, so the achievement of improved output power is highly anticipated.

In order to meet these demands, Gigaphoton’s G45K KrF laser realizes 50W of output power, 25% more than previous models, providing higher productivity-efficiency production of state-of-the-art memory chips. It also extends the lifetime of the main modules by 20% and greatly reduces the necessary downtime for maintenance, contributing to increased productivity. In addition, Gigaphoton’s “helium free” green technology is installed as standard, as with previous models, and “hTGM (Neon Gas Recycling System) is also available, which are also effective in reducing operational costs.

Katsumi Uranaka, President & CEO of Gigaphoton said, “With the rapid spread of the IoT and AI, improving state-of-the-art memory chip productivity is an urgent need for the chip manufacturers who are our customers. I am confident that the world’s highest output power class and reduced downtime due to module lifespan extension achieved by Gigaphoton’s G45K KrF laser can contribute to efficient production for our customers.”


Since it was founded in 2000, GIGAPHOTON has delivered valuable solutions to semiconductor manufacturers throughout the world as a laser supplier. In every stage from R&D to manufacture, sales, and maintenance services, GIGAPHOTON is committed to providing world-class support delivered from the perspective of everyday users.
