Wright Williams & Kelly, Inc. Examines Mask Defect Inspection Cost

Image Qualification Versus Direct Mask Inspection: And the Winner Is

PLEASANTON, CA--(Marketwire - September 25, 2007) - Wright Williams & Kelly, Inc. (WWK), a cost & productivity management software and consulting services company, announced today that it has published a report examining the cost structures of competing, on-going, mask defect inspection strategies for 193nm scanners operating at the 65nm node. The report addresses litho cell availability, inspection costs, opportunity costs, and mask costs. The report shows when each strategy is more cost effective. The report can also be customized for specific assumption sets and the data can be provided in TWO COOL® format. TWO COOL® is the semiconductor industry's de facto standard for cost of ownership (COO) and overall equipment efficiency (OEE) modeling.

"With the cost of litho clusters well in excess of $20 million, it is critical that these bottleneck tools be highly utilized," states David Jimenez, President of WWK. "Inspection strategies dramatically impact equipment utilization and capital productivity. However, with masks having the potential to cost in excess of $100,000 each, it is also important to understand when your inspection strategy will require back up mask sets and how those decisions ultimately impact the bottom line."
