Automated Defect and Yield Data Analysis

Klarity® Defect automated defect analysis and data management system helps fabs achieve faster yield learning cycles through real-time excursion identification. Klarity® SSA (Spatial Signature Analysis) analysis module for Klarity Defect provides automatic detection and classification of defect signatures that indicate process issues. Klarity® ACE XP advanced yield analysis system helps fabs capture, retain and share yield learning within and across fabs for yield acceleration. Klarity systems utilize an intuitive decision flow analysis, allowing engineers to easily create customized analyses that support applications such as lot dispositioning, review sampling, defect source analysis, SPC setup and management, and excursion notifications. Klarity Defect, Klarity SSA and Klarity ACE XP form a fab-wide yield solution that automatically reduces defect inspection, classification and review data to relevant root-cause and yield-analysis information. Klarity data helps IC, packaging, compound semi and HDD manufacturers take corrective action sooner, resulting in accelerated yield and better time to market.


On‐product Process Optimization, Diagnostics, Monitoring and Control

The OVALiS software suite is utilized by leading-edge semiconductor lithography and patterning teams for on-product process optimization and control. OVALiS uses a single database to combine metrology data with context information from various types of equipment, as well as mass context information from fab automation. Using simulation, diagnostics, monitoring, and process optimization, this data helps optimize and improve on-product performance. The OVALiS software suite consists of different modules that can be used independently, or synergistically, and can seamlessly integrate into a fab’s SPC, FDC and yield management systems.

5D Analyzer®

Advanced Data Analysis and Patterning Control

The 5D Analyzer® run-time process control solution supports analytics and visualization for advanced node process optimization, process monitoring and patterning control. It accepts data from a broad range of sources across the fab, including: overlay, reticle registration, wafer geometry, chamber temperature, films, CD, and profile metrology systems; process tools; and scanners. With applications such as advanced overlay analysis and correlation of reticle and wafer shape data to patterning errors, 5D Analyzer enables a variety of offline and real-time use cases for advanced patterning control.


Pattern-Centric Defect and Metrology Software Solution

The aiSIGHT™ software solution leverages acquired SEM (scanning electron microscope) images and chip design information to provide a broad set of defect and pattern measurement information. The aiSIGHT (Anchor Integrated SEM Image Guided Hotspot Toolkit) software is tool agnostic – using SEM images from all manufacturers’ e-beam inspection, review and metrology systems. aiSIGHT can detect and classify defects, perform massive metrology measurements, and measure specific patterns. By extracting previously unseen information from available SEM images, aiSIGHT helps chip manufacturers gain detailed insight into the defect or pattern issues that affect yield or final chip performance.

Anchor Pattern Centric Yield Manager

Automated Design Decomposition and Pattern Risk Scoring

The Anchor Pattern Centric Yield Manager begins by creating the Design Decomposition Database™ using a set of parametric search rules to extract patterns of interest. Patterns in the Design Decomposition Database are then scored based on all available information sources, including OPC simulation, statistical or geometrical sources (design signatures), and empirical sources such as pattern fidelity information extracted from SEM images. When all patterns are scored (or ranked), Anchor Pattern Centric Yield Manager:

  • Assesses the process marginality or risk of each pattern and generates pattern risk score trends over time
  • Compares a new tape-out against a reference design to identify pattern risk factors
  • Creates optical and e-beam inspection care areas
  • Performs improved defect sampling for SEM review
  • Provides pattern risk feedback to OPC / Lithography teams

Anchor Pattern Centric Machine Learning

Automated Design Decomposition and Parametric Rules Search

The Anchor Pattern Centric Machine Learning bridges the Printed Pattern Database and the Design Decomposition Database™ to enable entirely new opportunities for yield learning and process optimization by predicting pattern risk scores that are more reliable than purely statistical or geometrical signatures. Anchor Pattern Centric Machine Learning:

  • Builds a machine learning model from the data contained in the Printed Pattern Database
  • Predicts pattern risk scores on nearly all the patterns contained in the much larger Design Decomposition Database
  • Captures new SEM images that are continuously generated in the fab into the Printed Pattern Database
  • Enables continuous learning to improve its prediction accuracy moving it closer to an expert system


Automated predictive analytics for fab process and yield management

The SPOT® automated predictive analysis solution is a production machine learning platform used in chip manufacturing fabs. SPOT (Sample Plan Optimization Toolkit) improves the capture rate of critical defects of interest (DOI) by using a combination of customizable machine learning techniques and statistical algorithms. Inspection and review data is comprehensively analyzed on powerful, scalable computing architecture, using advanced machine learning models to identify and predict real defects of interest and separate them from nuisance defects. An optimized, targeted review sample plan is automatically generated which can discover more DOI and show wafer signatures previously buried in nuisance noise.


Inline Die-Level Screening

The I-PAT® (Inline Defect Part Average Testing) method allows automobile manufacturers to reduce the incidence of latent reliability defects in semiconductor electronic components, recognize at-risk die for exclusion from the supply chain and reduce the incidence of escapes of die that will fail prematurely from the fab. I-PAT runs on KLA inspection and data analytics systems. It begins by extracting defect characteristics from data collected for all wafers at critical process steps by the high speed 8 Series inspectors or the Puma™ laser scanning inspectors. I-PAT then leverages customized machine learning algorithms on the SPOT® production platform and the statistical analysis capabilities of the Klarity® defect management system to identify outlier defect populations so at-risk chips can be removed from the supply chain. By identifying die with outlier defect populations across critical process steps, I-PAT helps automotive chipmakers achieve high reliability and quality.


Reticle Data Analysis and Management

The RDC (Reticle Decision Center) comprehensive data analysis and management system supports multiple KLA reticle inspection and metrology platforms for reticle qualification in both mask shops and IC fabs. RDC provides a wide array of innovative solutions for reticle quality control, including KlearView™, Automatic Defect Classification, Lithography Plane Review, Defect Progression Monitor, Aerial Image Analyzer, and more (see Modules tab below). These RDC components drive automated defect disposition decisions, improve cycle time and reduce the reticle-related patterning errors that can affect yield. In addition to providing critical applications, RDC serves as a central data management system utilizing a high reliability, flexible server configuration.


Real Virtual Patterning

The PROLITH™ lithography and patterning simulation solution uses innovative models to accurately simulate how designs will print on the wafer. PROLITH is used by IC, LED and MEMS manufacturers, scanner companies, track companies, mask manufacturers, material providers and research consortia to cost-effectively evaluate patterning technologies, including EUV lithography and multiple patterning techniques. As a critically important modeling tool for all patterning processes, PROLITH helps lithographers understand how pattern printing is affected by multiple lithography variables while significantly reducing the time required to identify workable solutions.
