High Resolution Imaging Inspection
2365 high-resolution imaging inspection system

Product Description

The 2365 high-resolution imaging inspection system provides the sensitivity, flexibility, and intelligence needed to capture yield-relevant defects, while ignoring nuisance defects all on a cost-effective platform that has been proven in production. The 2365 imaging inspection system's superior sensitivity to all defect types makes it ideal for new technologies (such as copper, low-k dielectrics, and 193-nm resists) in advanced 200-mm and 300-mm fabs, with particular effectiveness for critical etch, critical CMP, photo, and engineering analysis. This imaging inspection system, which features iADC for fast, consistent identification and review of yield-limiting defects, allows chipmakers to quickly isolate the root cause of yield-relevant defects to improve yield learning and monitoring.

  • Provides 2x improvement in throughput over previous generation tool
  • Uses UV and visible light source and 0.12-mm pixel size to provide the improved inspection sensitivity needed for 65-nm node and below design rules
  • Delivers superior resolution and material contrast through selectable illumination (broadband UV, broadband visible, i-line, and g-line) and a high numerical aperture, enabling inspection of all process layers with full sensitivity to the entire range of defects
  • Enables superior color noise suppression through broadband illumination for ideal inspection monitoring of BEOL metal etch and copper CMP layers
  • Accelerates time to classified results and improves yield with inline automatic defect classification (iADC) and rule-based binning capability
  • Enhances return on investment in 300-mm manufacturing equipment with SEMI 300-mm automation-standards compliance
  • Provides 235x capital-investment extension through upgrade capability

Comprehensive Defect Inspection Solution
Multiple inspection technologies are required for a successful yield management program. The 23xx series and KLA-Tencor's eS31 incorporate revolutionary UV brightfield and e-beam technologies, respectively. They combine with KLA-Tencor's AIT series and its breakthrough high-throughput scanning technique to form the industry's only comprehensive defect inspection solution that addresses all stages of semiconductor manufacturing, from development through production. The mix of the three technologies changes depending on whether the fab is in development, ramp, or production, but all three are used throughout the entire lifetime of the fab.
