KLA-Tencor Introduces New Technology for Disk Drive Substrate and Media Defect Inspection
MILPITAS, Calif.--(BUSINESS WIRE)--
KLA-Tencor (NASDAQ:KLAC) today unveiled the Candela 7100 series for advanced defect inspection and classification of hard disk drive substrates and media. Built upon the production proven Candela line, the 7100 series is designed to help manufacturers identify and classify submicron critical defects such as pits, bumps, particles, and buried defects, for maximizing yield and lowering total cost of inspection.
"The Candela 7100 series is an innovative extension of our optical surface analysis technology that customers already recognize as the tool of record for defect inspection and classification," said Jeff Donnelly, group vice president of Growth and Emerging Markets (GEM) at KLA-Tencor. "With improved sensitivity and classification capabilities, the 7100 series' all-in-one solution is designed to reduce dependency on other tools, lower our customers' costs and provide them with faster time to results."
Continued growth in areal, or bit, density has driven the need for lower surface contamination levels, smoother disk surfaces, increased sensitivity to smaller defect sizes, and an emphasis on controlling specific defect types early in the process. Moreover, with magnetic recording head fly-heights shrinking, small defects now have a much larger yield impact. With industry-leading sensitivity, the Candela 7100 series is the ideal solution to address these industry challenges.
The hard disk drive industry continues to demand increasing price-performance for their customers, so manufacturers must remain cost competitive with faster time to results and statistically valid decisions. The Candela 7100 reduces dependency of multiple non-production tools and methods, such as an atomic force, scanning electron, and transmission electron microscopes, as well as electrical testing. Analyses currently being conducted by multiple inspection tools can now be done faster and at a lower cost on a single tool.
The Candela 7100 series is being qualified by Hitachi Global Storage Technologies (HGST), a leading storage technology company.
KLA-Tencor is currently accepting product orders. Shipments are scheduled to begin in October.
KLA-Tencor will also showcase the Candela 7100 series and other yield management solutions for the data storage industry Sept. 17-18 at the DISKCON USA 2008 Trade Show and Conference -- booth No. 115 at the Santa Clara Convention Center, in Santa Clara, Calif.
