Cimetrix products (part of the PDF Solutions portfolio) have long been powerhouses in semiconductor equipment connectivity and factory automation. For decades, they have helped equipment manufacturers and factories speak the same language—reliably, efficiently, and in strict compliance with SEMI industry standards. From foundational connectivity platforms to modern factory-wide solutions, Cimetrix products are known for being software that “just works” in the most demanding production environments in the world.
CIMConnect: The Gold Standard for SECS/GEM Implementation
At the heart of many tool integrations is CIMConnect, our signature SECS/GEM software product.
In the semiconductor industry, connectivity and control standards such as SECS-II (SEMI E5) and GEM (E30) are non-negotiable. Equipment must communicate flawlessly with host application systems, MES platforms, and other factory automation software. In this context, CIMConnect has built its reputation on rock-solid standards compliance, stability, and performance.
What makes it great?
- Mature, production-proven architecture
- Strict adherence to SEMI standards
- Robust HSMS (SECS-II over ethernet – SEMI E37) support
- Extensive logging and diagnostics
- High-performance message handling
For equipment suppliers, CIMConnect reduces cost and schedule risk. Instead of reinventing standard protocol stacks, engineering teams can focus on tool functionality and competitive differentiation—confident that connectivity is handled by industry-trusted software.
CIM300: Enabling 300mm Automation
As the industry transitioned to 300mm wafer fabs, automation requirements expanded dramatically. That’s where CIM300 stepped in.
CIM300 supports GEM300 standards such as:
- Carrier management
- Substrate tracking
- Process job management
- Control job management
300mm factory operations are governed by explicit automation scenarios that involve multiple connectivity standards concurrently. These scenarios support precise lot delivery and tracking; recipe selection, verification, and execution monitoring; full traceability for each wafer’s more than 3-month journey through the fab; and a number of other stringent automation requirements—all with little or no human assistance CIM300 provides the structured framework equipment suppliers need to meet these demands without building sets of complex interconnected state machines from scratch.
In summary, CIM300 is not just a message implementation platform—it’s an automation accelerator.
CIMPortal Plus: Driving EDA/Interface A Excellence
As fabs move toward data-driven process control and advanced analytics, EDA/Interface A has become a strategic requirement rather than a nice-to-have optional capability.
Whereas CIMConnect and CIM300 focus on traditional SECS/GEM and GEM300 connectivity, CIMPortal Plus plays a pivotal role in advanced data integration through the SEMI EDA (Equipment Data Acquisition) standards suite (E120, E125, E132, E134, E164), also commonly known as Interface A.
EDA/Interface A introduces a far richer and more scalable data collection paradigm than classic SECS/GEM messaging by leveraging equipment metadata model element definitions, structured parameters, multi-client web services-based networking, and powerful subscription-based data collection. CIMPortal Plus is designed to fully support this advanced capability, enabling fabs to access high-volume, high-density contextualized equipment data in a standardized and scalable way.
With CIMPortal Plus, manufacturers can:
- Implement SEMI EDA/Interface A standards with confidence
- Expose structured equipment metadata models
- Support flexible data collection plans
- Deliver high-throughput, subscription-based data streams
- Simplify customer validation and acceptance testing
As fabs increasingly demand deeper visibility into equipment and process performance, single device traceability, diagnostics and predictive analytics, EDA compliance is no longer optional—it is expected. CIMPortal Plus helps equipment suppliers meet these expectations efficiently, reducing integration friction while elevating the value of their tools within advanced manufacturing environments.
CIMControlFramework: A Solid Foundation for Equipment Control
Modern semiconductor tools are software systems as much as mechanical ones. CIMControlFramework (CCF) addresses this reality by providing a modular, structured framework for equipment control software. By abstracting common equipment behaviors into a reusable framework, CCF significantly reduces engineering risk and long-term maintenance costs.
CCF helps development teams:
- Achieve consistent tool behavior
- Greatly reduce effort required for material handling and other non-process behavior
- Improve maintainability and testability
- Lower overall support costs, especially where multiple product lines are concerned
In complex tools with multiple modules, load ports, and process chambers, consistency is everything. CCF gives teams an architecture that scales as tools evolve.
EquipmentTest – Ensuring GEM Compliance
Modern equipment development demands earlier validation. EquipmentTest’s host simulation capabilities and testing tools allow equipment suppliers to:
- Validate GEM/GEM300 behavior long before factory installation or customer acceptance testing
- Simulate host interactions
- Perform regression testing
- Accelerate fab acceptance
This reduces late-stage integration surprises and shortens time-to-market.
EDATester: Accelerating EDA/Interface A Validation
As factories increasingly adopt the EDA (Equipment Data Acquisition) standards, the validation and performance testing processes become more complex. EDATester provides a powerful solution for verifying compliance with SEMI EDA standards before tools ever reach the fab floor.
With EDATester, equipment suppliers can
- Validate EDA metadata models
- Test data collection plans
- Simulate client interactions
- Identify compliance issues early in development
- Automation much of the above!
EDA implementations can be intricate, involving XML models, web services, and structured data definitions. EDATester reduces uncertainty by providing a controlled, standards-aware test environment. The result is faster customer acceptance, fewer integration surprises, and greater confidence in advanced data capabilities.
A Strong Future Ahead
The semiconductor industry continues to evolve—advanced process nodes, heterogeneous integration, smarter factories, and increasingly autonomous operations. As factories push toward greater efficiency, visibility, and intelligence, the need for robust, standards-compliant connectivity software will only grow.
