SEMICON Japan 2012 was a great experience, and it was amazing to see the excitement and interest in new developments as the industry prepares for growth in 2013. We were able to showcase Cimetrix products at the booths of Meiden and Rorze, our distributors in Japan. We also displayed CIMControlFramework in the MKS Instruments booth.

Meiden and Rorze demonstrated CIMPortal 2 for the many OEMs we have in Japan currently using CIMPortal 1.x.  CIMPortal 2 provides the tools for equipment companies to comply with the SEMI E164 standard when they are implementing an EDA/Interface A connection. The E164 standard, approved by SEMI this year, was developed so that companies using EDA/Interface A connections can generate a more consistent and high-quality definition of their equipment’s model, as represented in the metadata file. The CIMPortal 2 toolkit includes many features that reduce development time and effort, including a drag-and-drop equipment model builder and compliance checker.

We also presented and demonstrated the Wait Time Waste (WTW) and Fingerprinting projects we are developing in collaboration with ISMI. Due to an emphasis on productivity improvement demands, many semiconductor fabs are very interested in hearing about how they can reduce costs using the WTW metrics and methods in development. Fabs are also interested in fingerprinting – also known as equipment health monitoring – in order to reduce the time to repair equipment and avoid downtime. Alan Weber, Director at Cimetrix, taped a presentation and demonstration of fingerprinting that was shown in the Meiden and Rorze booths.

We also highlighted our CIMControlFramework equipment software framework at the Meiden, Rorze, and MKS Instruments booth. OEMs are looking for an equipment control software solution they can use for high-volume applications, and they like the concept of being able to manage the development in-house. By using a flexible, extensible, configurable framework, OEMs can implement custom extensions for new customers and design the next generation of system internally, allowing them to maintain control of their own development process. Rorze now offers not only CIMControlFramework as a stand-alone product, but also packaged with robot hardware including EFEMs and Vacuum Platforms.

Kerry Iwamoto, the Managing Director of Cimetrix Japan K.K., and I presented at the SEMI Productivity Standards Workshop, which focused on Wait Time Waste. This workshop, which was one of the better-attended sessions, presented new proposed standards development activities to improve manufacturing productivity and reduce costs. Kerry and I described plans for developing a SEMI standard for Wait Time Waste methods and metrics that will allow semiconductor fabs to measure product wait time and use that data to reduce waste and cycle time. We showed how the WTW Reference Implementation (WTWRI) developed by Cimetrix can help fabs pinpoint process delays and determine how to reduce them.

Japan is going through some tough times both politically and in their semiconductor industry. But now is the time to work closely with high volume OEMs in Japan as they retool their strategy for the next phase of semiconductor growth.

We had a great time at SEMICON West as ISMI/SEMATECH and Cimetrix talked about our joint fingerprinting project. There was a lot of interest in fingerprinting, which is also sometimes known as equipment health monitoring (EHM) or signature analysis. In a semiconductor manufacturing context, fingerprinting is defined as “a set of data variables associated with the component being fingerprinted, sampled at some rate over a time period, transformed and then analyzed using a set of mathematical techniques, to generate a result representing the state of the unit during that timeframe.”

Both equipment suppliers and semiconductor fabs are interested in fingerprinting since currently there is no automated process to predict imminent equipment problems. Predictive maintenance applications are still in the R&D phase, so today, fabs are using statistical process control (SPC) to monitor equipment to predict potential problems, or fault detection after the machine fails or exhibits sub-optimal performance. With fingerprinting, the fab’s equipment engineers can monitor the behavior of key equipment components to predict imminent problems and alert the fab to take the necessary steps to prevent equipment failure.

Equipment engineers and process engineers at the fabs can also use fingerprinting to characterize newly delivered tools and establish a baseline for key component behavior across a range of operating points. What’s more, they can verify fingerprints of key equipment components during or after a production run to ensure the component process capability is in normal operating range. They might also define a special set of fingerprints to help understand why a particular tool has had an increase in FDC violations.

One of the points we explained to people about the project we are developing with ISMI is that the fingerprinting application is not dependent on any other Cimetrix software product. The application is standalone, and can be used on many different types of machines. Moreover, this application is for both new equipment in development as well as equipment currently deployed in the field.

If you would like to hear more about the fingerprinting project, or see a demo, contact Jackie Ferrell at ISMI, or go to Contact Cimetrix and tell us how we can connect.

We had a lot of interest in EDA/Interface A SEMI standards at our booth at SEMICON West 2012 in San Francisco during the week of July 9. Equipment Data Acquisition (EDA), also referred to as Interface A, is made up of SEMI standards SEMI E125, E134, E120, E132, and supporting standards. EDA offers semiconductor manufacturers the ability to collect a significant amount of data that is crucial to the manufacturing process, including descriptions of the equipment's structure and behavior. This data is represented on the tool as an equipment model, which is communicated to EDA clients as metadata sets. The metadata includes the equipment components, events, and exceptions, along with all the available data parameters.

One of the challenges with creating an equipment model and the resulting metadata sets is the variability with which the model can be created. It is possible for one tool to create a model that is compliant with the standards, but is quite different from the model for another tool, which is also standard compliant. This makes it difficult for the fabs to then reliably know where to find the data they are interested in from tool to tool. This issue has been addressed in SEMI Ballot 5002B which  defines the common metadata set that will support consistent implementation of EDA/Interface A Freeze Version II. Through our leadership role in the DDA Task Force, Cimetrix has played a major part in defining Ballot 5002B.

SEMI is in the final proof review of the standard that resulted from the5002B ballot, which SEMI will soon publish as the E164 Common Metadata Standard. With this new specification, equipment modeling will be more clearly defined and provide more consistent models between OEMs, which will make it easier for EDA/Interface A users to navigate models and find the data they need. Some semiconductor manufacturers, such as GLOBALFOUNDARIES, will require both compliance with E164 and validation of the compliance with the ISMI/SEMATECH Metadata Conformance Analyzer (MCA).

MCA is the industry standard means for automated checking for conformance of equipment metadata to applicable portions of the SEMI standards and ISMI guidelines. By using MCA, both OEMs and semiconductor manufacturers will be able to attain consistency in the representation of 300mm data, objects, and events within EDA/Interface A. Those supported standards include E30, E40, E87, E90, E94, E116, E157, and the new E164 standard.

One important thing to recognize is that, since it is possible to create a Freeze Version II compliant interface that will not pass MCA testing, understanding the requirements for compliance to both before beginning the design.

For more information about EDA/Interface A Freeze Version II, as well as the new E164 and MCA testing, contact us at Ask EDA/Interface A Question. We are recognized as one of the industry leaders in SEMI standards. Let’s talk and find out how we may be able to help.

This is an exciting time as we prepare for SEMICON West 2012 in San Francisco next week.  We have demonstrations of our products, and we are particularly excited to discuss two projects we are actively working on with ISMI. These projects, which are high priorities for ISMI’s member companies, are Fingerprinting, also known as Equipment Health Monitoring, and a Wait Time Waste Reference Implementation. Active ISMI companies on these project teams include Micron, Intel, GLOBALFOUNDRIES, IBM, and TSMC.

Fingerprinting

In Fingerprinting, the concept is to define and execute models for monitoring tool component behavior. Think of this as generating tool-specific EPIs (equipment performance indicators). Once that is done, we can compare the real-time results with both specifications and historical production values, and generate conclusions regarding the equipment. To support the process, companies can incorporate data from external sources, such a fab maintenance databases, or engineering databases.

Ultimately, OEMs will be able to ensure consistency of delivered equipment, reduce tool acceptance time and effort, and reduce their field service costs. Semiconductor fabs will be able to use this application to get detailed equipment component performance measurements, and monitor equipment health KPIs to get an early warning of any impending failures.

Wait Time Waste

ISMI’s Wait Time Waste project was initiated to develop metrics to measure time waste systematically, as well as defining the data collection and analysis methodology to apply these metrics. A potential industry standard will provide a common language to measure and identify wait time waste, and create a market for software suppliers to provide the measurement and analysis tools.

Semiconductor fabs will be able to identify sources of variation in basic tool throughput and establish an objective basis for productivity improvement. Equipment suppliers will also benefit by having the ability to improve their tool-level scheduling algorithms and measure their products’ performance levels.

Cimetrix project engineers will be available in the booth to demonstrate these applications and discuss how they can be of value to our customers and prospects. These types of projects represent a further broadening of Cimetrix’ capabilities into equipment- and factory-level analysis applications that leverage the company’s strengths in accessing and communicating high quality equipment data.

We hope to see you at Booth #1241 at SEMICON West!

If you are attending SEMICON West in San Francisco, and you are interested in learning more about the SEMI PV2 equipment communication standard, consider one of the events presented by the PVGroup and SEMI. 

The Standards Technical Education Program (STEP): PV2 - Guide for PV Equipment Communication Interfaces (PVECI), held at the San Francisco Moscone Center, Tuesday, July 10, 2012, from 1:00PM to 5:00PM (PDT) provides background information on the standard and technical explanations of GEM and PV2 (PVECI). Cimetrix personnel will be on hand to present at the workshop.

The course will explore the content, usage, and benefits of the PV2 communications standard and associated SEMI guidelines, and discuss how the PV2 standard can help make the solar power industry more competitive amid consolidation of suppliers and other recent trends.

The workshop will provide:

• Introduction and background of PV2 development

• Brief history of SEMI communications standards

• GEM concepts

• PV2 Messages

• PV2 Applications

• Implementation of the PV2 standard

Attendees will learn the rationale and context of PV2, understand the set of SEMI Standards involved, and how PV2 is applied to host communications for PV equipment. If you are an engineer designing equipment for solar panel production, or if you are a field service engineer working with solar companies, or if you are a manager, process engineer,  equipment buyer, or software engineer, you should take a look at how the program can give you insights and understanding that will help you in your current assignment.

If you are going to attend SEMICON West in San Francisco, July 10-12, 2012, at the Moscone Center – please visit us at booth #1241 and let us tell you how we can support your next equipment control project using our CIMControlFramework™ equipment automation software.

As more and more customers use CIMControlFramework software on different tool types (strip tools, MOCVD, defect inspection, chemical deposition, and a host of others), we have also generated training material in the form of labs our customers can use to help them get up to speed faster and learn how to implement designs easier and more effectively.

Come to our booth and take a look. When we demonstrate CIMControlFramework, we will show you the labs we supply with the software. Those labs include not only topics such as installation and fundamentals, but also sections such as scheduling and material movement, user interface development, and I/O and communications.

We can also discuss our product support and training classes that will help get your team up and running on SEMI factory connectivity standards, and their implementation, equipment control, and C# and Agile software development.

We look forward to seeing you at our booth at SEMICON West.

If you are interested in learning more about the SEMI EDA/Interface A factory connectivity standard, you can look at our EDA/Interface A web page, or download our white paper. But - if you are going to attend the SEMICON West event in San Francisco, July 10-12, 2012, at the Moscone Center - you can also visit us at Booth #1241 and hear about how we can support your requirements.

So many people have questions regarding EDA/Interface A standards and how to implement them. Freeze Version I, Freeze Version II, common metadata, MCA, 5002B – it seems like a confusing array of issues, numbers and acronyms. Cimetrix can guide you through the process faster and with less risk than any alternative.

For example, if you are developing a new system that needs to implement an EDA connection, come by our booth to see a demonstration of our CIMPortal software. We will show you how it can guide you as you set up the equipment model, the basic element in an EDA solution. For example, below is an example of how a designer can browse the E120/E125 structure of the equipment model using the E125 web services APIs.

Equipment Metadata Browsing

We can also discuss what it takes to get your equipment ready to be accepted at the fab, and how you can work with the fab to pass their acceptance tests.

If you work at a semiconductor fab, come by and talk with us about how you can use this SEMI standard to stay competitive and increase productivity while decreasing costs. Let’s talk about common metadata and how that can make it easier for you to access the data available through EDA. We can also discuss the challenges of dealing with different equipment models and garnering consistent data to analyze equipment processes. We can tell you our experience of working with semiconductor fabs to implement EDA and establishing acceptance criteria for the interface. If you would like, we can demonstrate our EDAConnect software that enables you to set up your EDA connection to the equipment.

We can discuss our product support and training classes that will help get your team up and running on the standard and the implementation process.
