DANBURY, CT -- October 23, 2001 -- ATMI, Inc. (Nasdaq: ATMI), an industry-leading provider of specialty materials and services to the worldwide semiconductor industry, today announced its NOWPak Cube(tm) space-premium photoresist packaging. Within an industry-standard footprint, customers can hold and dispense 50% more photoresist than conventional packaging. This can significantly reduce packaging costs and change-out frequency, helping to reduce waste and improve inventory management. Dennis Brestovansky, ATMI Senior Vice-President and General Manager of ATMI Packaging, said, "Space within semiconductor fabrication plant chemical cabinets is premium real estate. We worked with our customers to create a solution to the need to store more photoresist in the same space -- replacing the wasted space of a cylindrical footprint with the efficiency of a cube." Bob Lord, Vice-President Sales & Marketing for ATMI Packaging, said, "By moving to the additional volume available within a cube compared to a cylinder, we've been able to increase capacity by 50%. The 1.5 gallon NOWPak Cube fits easily into the same space for existing 1 gallon packaging and ultimately allows our customers to fit a square peg into a round hole." ATMI's NOWPak Cube works the same as all NOWPak products -- and it works with all NOWPak closures and SmartProbes. The NOWPak product line is industry-preferred for deep ultraviolet (DUV) photoresist. Low-k dielectrics, copper electro-chemical deposition materials, HMDS (Hexamethyldisilazane), and anti-reflective coatings are all more efficiently delivered using the NOWPak technology.
