Dow Becomes First Materials Supplier to Install 193 nm Immersion Scanner in Korea [#DowInvestorDay]

Today, Dow is the only global supplier with two 193 nm immersion scanners available to support customers' development efforts, with one already running in its Marlborough, Mass., facility. Dow also has a 193 nm dry scanner at its Cheonan, Korea facility and the combination of these investments enable Dow to significantly shorten both product development cycle times and manufacturing lead times to meet customers more advanced requirements.

In a related development, the company is also expanding its advanced photoresist manufacturing capacity at its operations in Cheonan, Korea. Increasing volume capacity for photoresist and ancillary materials allows Dow Electronic Materials to enhance customer responsiveness, shorten cycle time to market and support market share growth. Key products to be manufactured in Korea are Dow's 193 dry photoresist, 193i photoresist and anti-reflective coatings. The Cheonan facility started its production ramp up in 2011 and will continue to expand capacity through late 2012.

"We are continuing to see strong growth in Asia, especially for photoresists and related materials," said Sam Shoemaker, global general manager for Dow Electronic Materials' Semiconductor Technologies business. Shoemaker continued, "As a result, we have made substantial investments in support of our Electronic Materials business in the region. Installing these tools for customer R&D efforts in Korea and increasing our volume manufacturing capacity in Cheonan are major steps forward in our continued efforts to exceed the expectations of our customers worldwide. These investments in Korea extend our lead in providing worldwide customer support for advanced lithography."
