In July 2006, ADE Corporation was acquired by KLA-Tencor Corporation. ADE Corporation worked in metrology and inspection systems for the semiconductor wafer manufacturing industry. In addition, the Company is a supplier of metrology systems to the semiconductor device, data storage and optics industries. Its systems analyze and report product quality at critical manufacturing process steps, sort wafers and disks and provide manufacturers with quality certification data. Semiconductor wafer and device and data storage manufacturers use its systems to improve yield and capital productivity. The Company's products have evolved from single instruments used in off-line engineering analysis to multi-function systems for automated in-line monitoring of process-induced defects throughout the wafer and disk manufacturing processes. Its systems are designed to deliver the high throughput, reliability and information and analysis necessary to meet the demands of increasingly complex and time-sensitive manufacturing processes.
