structure, depending on when they were defined Models may not provide sufficient visibility into equipment behavior Interface performance may not match expectations if control system was not redesigned All of this is improving rapidly as fabs take a more prescriptive approach to their automation specs Valid Entries: Comply Comply by (Date) Partially Comply (Notes) Do no comply N/A EDA adoption status Cumulative # of production tools installed
All are now requiring latest SEMI Standards for equipment modeling and data acquisition Principal Motivation: Flexibility Data collection plan Changing requirements Multi-client architecture We are here ! 9 Unifying concepts/relationships Generalizable from SEMI EDA standards Manufacturing Stakeholders and their KPIs
Data Collection Plans Equipment Data Consumers Data Equipment Model Unifying concepts Metadata model and data collection plan (DCP)
Shared equipment model benefits Driven by factory requirements Structure exactly reflects equipment hardware organization Provides complete description of all useful information in the equipment Always accurate and available no additional documentation required* Common point of reference across all factory and supplier stakeholders Source of unambiguous information for database configuration Reduces integration engineering * As long as it can be queried from the equipment Other Components
Process Module #1 Gate Valve Data Substrate Location Utilization More Data, Events, Alarms Process Tracking Issues with SEMI GEM data sources Equipment model is not explicit GEM/GEM300 will persist as the principal
command and control interface Data collection mechanisms are fixed and limited Event reporting Trace reporting Variable status queries Equipment model must be derived from lists of variables, events, constants, state machines, etc. The recent SEMI E172 standard (SECS Equipment Data Dictionary) offers a partial solution But must be specified if it is to be delivered SEDD SECS Equipment Data Dictionary Schema and examples .

Interoperability of OPC UA components Requires compatible mappings and profiles Figure 1 The OPC UA Stack Overview (from Volume 6) Figure 1 Profile Conformance Unit Test Cases (from Volume 7) Issues with external sensors Implementations are factory specific Typical challenges. 1. Finding a sensor that works 2. Sampling/process synchronization 3. Dealing with multiple timestamps 4. Scaling and units conversion 5. Applying factory naming convention
6. Associating context and sensor data 7. Ensuring statistical validity 8.

A S1 S2 S3 * DCIM = Data Collection Interface Module Issues with equipment log files Their formats are custom designs Optimized for ease of creation NOT consumption
Type of information included varies Mixture of events, parameters, alarms Mixture of critical data and just in case stuff Parameter values often stored in native, binary form Format may change throughout the log Not just a simple set of identical records Multiple sections, headers, record layouts, even files Issues with equipment log files They disappear over time Usually circular file system Fixed limits for file sizes and number When limits are reached, oldest files are overwritten Retention period may vary with activity And available storage space
Issues with equipment log files They reside on the tool Part of the local file/directory system Access methods dictated by platform technology Special permissions may be required to keep from invalidating tool warranty They depend on the tools clock So the timestamps are almost always wrong May be able to correct reports if offset from factory reference clock is tracked continuously Example solution architecture Equipment Log File Processing XML/Text Model

Repository (Historian) Key system components Data Source Model (DSM) Foundation for entire system architecture Could be derived from EDA equipment metadata model Identifies type/name of the system that generated log file E.g., process equipment, supplier, tool type, model name, etc. Maps contents of custom log file into standard tool data reports using unique keys for items of interest Keys are assigned in the log file parser Keys appear in correct equipment structural context in the DSM, resulting in proper sourceId (location) and parameterName
Includes optional elements for Data type declaration: necessary for subsequent report processing Units conversion: raw binary to scaled engineering units Event augmentation: generate enumerated state values Key system components Data source parser This is where most of the NRE (non-recurring engineering effort) will be spent Some of this will be custom code, but it is also possible to use commercial ETL (extraction, transformation, and loading) software in many cases Example: elastic Filebeat and Logstash products Perhaps elasticsearch and Kibana for centralized storage and visualization as well The back end of each parser is a standard EDA-compliant data
report generator Output format for all sources is the same This is NOT rocket science just tedious Implementation process For each vendor/equipment type Analyze format and content of log file Identify data items of interest Dont have to collect everything in the log file Develop custom parser, assign keys to items of interest Create Data Source Model with keys in hierarchical context May also derive it from EDA equipment metadata model Include scaling, units, and new state value elements as needed Validate with DSM validation utility
