KLARITY LED: Defect Analysis and Data Management System for LED Yield Enhancement
Based on the industry-leading KLARITY Defect product for integrated circuit manufacturing, the new KLARITY LED provides a high performance solution for LED device makers, including automated in-line scan analysis for the entire fabwide manufacturing process. The LED industry is evolving from traditional tool-centric manual defect checks, with automated optical inspection only at the end-of-line stage, towards adopting sophisticated fabwide process control and defect analysis with in-line inspection. As a result of front-end to back-end connectivity, KLARITY LED delivers faster excursion detection and root-cause analysis than prevailing industry methods to enable effective decision making, thus helping reduce the impact of materials risk and improve yields. With KLARITY LED, KLA-Tencor introduces to LED device makers an advanced in-line alternative solution for automated defect analysis of LED production processes, and an option to more efficiently share performance and reliability data within their organization for faster yield learning, while replacing existing labor-intensive manual report generation methods.
Designed to help LED device makers accelerate yield learning cycles and prompt immediate corrective action, KLARITY LED includes:
- Automated analysis (intelligent statistical process control excursion and baseline monitor)—supports faster time-to-corrective action with automated knowledge-based reports, extensive drill-down capability and practical decision flow analysis that previously required expert intervention and interpretation
- Advanced Defect Source Analysis—automates the process of root cause analysis for defect sources providing flexible graphical analysis of common and adder defects
- Proprietary Spatial Signature Analysis —identifies spatial signatures, tracks dynamic signature count and leverages stack wafer signatures to identify the root cause for faster detection and corrective action
- Defect image review—provides wafer map point and click access, as well as an image gallery, allowing device makers to validate classification and defect transition commonality identification and rapidly generate automated reports
- Repeater defect detection—identifies repeat defects across an individual wafer, as well as from wafer to wafer
KLARITY LED complements KLA-Tencor’s wafer inspection systems—including the new ICOS WI-2220—to provide an enhanced LED-specific portfolio solution for high return on critical LED inspection investments.
ICOS WI-2220: Scalable Defect Inspection and Improved Cost of Ownership in LED Process Control
The ICOS WI-2220’s automated optical inspection capabilities help LED device makers realize increased yields and reduced production costs. With the ICOS WI-2220, device makers can automate inspection of smaller die sizes that inhibit manual inspection, and for larger die sizes that require rapid corrective action to limit costly materials risk. The new system allows defect inspection of whole and diced wafers up to 200mm, with macro inspection sensitivity in the pre- and post-dice inspection (i.e. front- and back-end) of LED wafers.
Compared to similar products on the market today, the ICOS WI-2220 provides sensitivity to critical defects—while minimizing noise introduced by process variations—and offers outstanding over and underkill performance (die misclassification) at high inspection speed. The new system also offers low-image distortion, advanced optic filtering, rule-based binning (RBB) for real-time auto defect classification, and advanced metrology capabilities at high inspection throughput as a result of new proprietary inspection and data processing technology. This enables increased yields in the manufacturing process through yield base line improvement, excursion control as well as improved dispositioning in outgoing quality control inspections.
