Industry News, Trends and Technology, and Standards Updates

As a child I was an avid model builder—airplane models, trains, engines, cars, ships, even monsters (anyone remember “The Visible V8” and “The Creature”?)—anything I could get my hands on. At the time I didn’t reflect on the source of this fascination, but with the benefit of hindsight, it is clear that these models provided an interactive, tangible way to visualize, explore, understand, and enjoy the topics that were interesting to me. It was a way to enrich an otherwise intellectual activity.

In fact, when Hurricane Carla ravaged the Texas coast and cut our electricity for 3 days, one of our luckier neighbors snaked an extension cord over the fence, which provided just enough power to run the refrigerator, a small black-and-white TV, and… you guessed it… my electric train. 

More than four decades later, I still enjoy working with models, but in the high-tech manufacturing domain, they often operate in the reverse direction, providing a logical way to interact with and understand physical entities, like materials, fixtures, processes, devices, components, equipment, and entire systems. And as important as various model types have been throughout the relatively brief history of the semiconductor industry, they are increasingly an integral part of the “Smart Manufacturing” initiative that is sweeping a wide range of industries worldwide. 

The focus of my next few blog posts will be the specific models that are inherent in the communications interface definitions for manufacturing equipment, subsystems, and other devices that are expected to cooperate over the [Industrial] Internet of Things. Our first post in this domain almost a year ago introduced the notion that the metadata models called for in the latest generation of SEMI Equipment Data Acquisition (EDA) standards were already directly aligned with the Industry 4.0/Smart Manufacturing vision. This series goes into much more detail, showing how specific sections of the equipment models in the GEM and EDA standards directly support many of the factory monitoring, analysis and control applications that are essential for running a Smart Manufacturing enterprise (see Substrate Management example below).

Moreover, to the extent that the structure and content of these models can truly be standardized, their associated applications can be process- and supplier-independent, greatly reducing the development and support costs for the factory IT departments while providing useful capabilities for the production engineering and operations stakeholders.

To get a feel for the overall direction of this series, download the presentation "The Role of Models in Semiconductor Smart Manufacturing",  along with the transcript,  from the APC Conference held last October in Phoenix. Then watch for subsequent postings that address specific applications, from productivity (OEE) monitoring, material tracking, product traceability, process execution monitoring, and beyond.

We look forward to your feedback and to sharing the Smart Manufacturing journey with you.

Since the concept was first articulated in 2011 by a German government-supported program promoting deeper integration of manufacturing software and hardware across the production value chain, the term “Industry 4.0” has gained recognition and momentum as the rallying cry for the 4^th industrial revolution (see left Image by Christoph Roser at AllAboutLean.com). Wikipedia  summarizes it like this: “Industry 4.0 facilitates the vision and execution of a ‘Smart Factory.’ Within the modular structured Smart Factories of Industry 4.0, cyber-physical systems monitor physical processes, create a virtual copy of the physical world, and make decentralized decisions. Over the Internet of Things, cyber-physical systems communicate and cooperate with each other and with humans in real-time…” 

This definition may lead you to ask “What aspects of Industry 4.0 are truly revolutionary, and what technologies and tools are available today that would enable me to start building “Smart[er] Factories?” In this blog, I offer some potential answers to these questions that put the vision of Industry 4.0 within reach for automation practitioners familiar with the latest generation of SEMI Standards.  

Semiconductor manufacturers have been collecting and using data from the equipment in their factories for decades. Throughout this period, device sizes and process windows have shrunk continuously according to Moore’s Law, and the SEMI Standards have evolved by necessity to support the insatiable demand for data exhibited by the process analysis and control applications that keep a modern fab running profitably (see left). The newest of these standards, the Equipment Data Acquisition suite (EDA, also known as “Interface A”), provides the power and flexibility to support a wide range of critical manufacturing applications and human users with ever-changing requirements; moreover, these standards can be deployed in a variety of system architectures without disturbing the “command and control” capabilities of existing factory systems.

“What does all this have to do with Industry 4.0?” To understand this, let’s look at the foundation of a “Smart Factory,” the collection of the many thousands of devices that might need to communicate over the so-called “Internet of Things.” 

We already see evidence that the availability of low-cost, low-power, networkable computing hardware will likely result in an explosion of “smart sensors” and other intelligent devices on the factory floor. However, as social scientists have observed over the millennia, groups of smart individuals don’t necessarily exhibit smart behavior in the aggregate, so what additional attributes must these devices possess to be good citizens of a collaborative, Industry 4.0 environment? How will these devices communicate effectively with one another? And what oversight will be required to ensure this communication achieves the ultimate manufacturing objectives?

As a starting point, I propose that each device, or manufacturing “thing,” at a minimum should be discoverable, autonomous, model-based, self-aware, communicative, and well-behaved. Depending on the role the device must play, it might also be self-monitoring, capable of defending itself (secure), and a consumer of data from other devices/systems as well as a provider. So defined, these devices would need a minimum of external monitoring and supervision (read “management overhead”) to perform their basic functions, but would rely on higher-level systems to provide specific objectives, instructions, and constraints (read “configuration, recipes, and limits”) for their operation in a given context and timeframe.

I realize that’s a lot to absorb at once, but now imagine that each of these devices could implement a subset of the services called for in the EDA standards, especially those defined in E120/E125/E164 (equipment modeling and standard metadata modeling), E132 (session management), and E134 (data collection management). Consider the collaboration among independent devices and systems this would enable…and ask yourself, how much closer to the vision of Industry 4.0 can you possibly get?

I hope the ideas above were useful…or at least thought-provoking. We’ll be developing this theme further in the coming months, but I wanted to use this blog as a conversation starter. We’d love to hear your feedback, so give us a call, or feel free to reach out to us.♦

With the new year, comes a major new initiative for Cimetrix to grow the markets for its products.  The company used the transition to 300mm manufacturing to establish a leadership position for its current product portfolio in the semiconductor industry. However, the company is starting to have success expanding into adjacent vertical markets that includes disk drive, display, LED, and photovoltaic. The objective of this new initiative is for Cimetrix to leverage its experience, technology, and product portfolio gained in the advanced semiconductor manufacturing industry to expand the markets for Cimetrix products. We will be exploring new opportunities in our current adjacent markets as well as possible new markets such as SMT and electronic assembly.

To head up this initiative, Ranjan Chatterjee has joined the company in the role of Vice President, Emerging Business and Technology Office. He will focus on extending and introducing Cimetrix’ portfolio of products into Industry 4.0 and Industrial Internet of Things (IIoT) initiatives by interfacing manufacturing equipment with big data and analytics tools. The data generated by devices connected via Cimetrix products can also be enlisted to bolster another methodology often used with lean manufacturing—Six Sigma. With the improvements in cloud and big data tools and infrastructure, one can use these methodologies on data with much bigger volume, velocity, and variety. This enables process control and a lack of variation of products. Processes can be monitored and corrected in real-time instead of inspecting machines merely at completion, and eventually this will help improve yields and reduce scrap. Specifically, manufacturers will need to establish a robust data infrastructure that works across the broader array of machines on the shop floor while breaking down protocol barriers so the machines can communicate effectively and in real time.

Manufacturers will also need to establish a bidirectional data flow so they are not only collecting information from equipment, but also pushing control back to the machines to optimize their usage. Manufacturers that can capture the right information, sift through it, and use it at the right time will be the ones that succeed.  Cimetrix intends to be a leader in enabling this vision. Ranjan’s decades of experience at Motorola and in the industry as a whole in software development, big data, cloud, process control, and lean manufacturing will enable Cimetrix to both adapt and develop products and partnerships to enable a robust ecosystem for a compelling solution.

Ranjan’s relationship with Cimetrix is not a new one as he is a former client. While at Motorola, Ranjan oversaw the development and deployment of a standards-based factory control system for SMT and assembly, which encompassed 24 factories around the world, and connected to over 20,000 pieces of equipment using the first generation of Cimetrix connectivity software. At that time, it was the leader in cell phone manufacturing and the largest purchaser of SMT equipment in the world. More recently, Ranjan has worked with companies developing and deploying systems using cloud technologies, big data analytics, and various modern technologies with a global software development team.

Ranjan is extremely excited to join the Cimetrix team as he sees many opportunities to leverage the latest cloud and big data analytics with Cimetrix core expertise and product portfolio into new markets for Cimetrix. He sees great potential for expanding Cimetrix in this new direction and we here at Cimetrix are looking forward to Ranjan leading the way.

This week Cimetrix exhibited at SEMICON Europa 2015 along with about 400 other companies in the semiconductor industry in Dresden, Germany. The leading trade fair offered a chance for members of the industry to learn about new topics, information, and opportunities to help support and further develop the semiconductor industry across Europe.

An estimated 6,000 were in attendance at this SEMI-sponsored event. Some of the highlights of the three-day event were:

• The Industry 4.0 Session: The term "Industry 4.0" has been established to describe the penetration of information science into manufacturing forming the next industrial revolution. The TechArena provided information about different aspects of this process.

• The Emerging Research, Materials and Processes Session: The nanoelectronics research community is continuously exploring a range of new materials to enable further scaling of semiconductor devices and associated technologies, as well as many potential methods to create these materials with methods that allow utilization for future technology nodes. In this session several of these new materials and process developments were discussed by experts in their specific fields. Focus was on the unique properties of the materials or processes, what makes them specifically suitable for targeted applications, how they are characterized and/or how they can be fabricated. Among the topics that were presented were the newest developments for GaN processing, two-dimensional semiconductors devices and fabrication, metal organic frameworks as low-k materials, advanced memory materials such as FeRAM or MRAM Spintronics, and Selective Atomic Layer Deposition.

• The Semiconductor Technology Conference (STC): This conference explored the efforts of our industry to ensure productivity enhancements for future advanced technology nodes, considering both a wafer size transition, and a continuation of current state of the art and smaller wafer sizes. Updates from around the world on wafer size transition activities were heard and there was a dedicated focus on “beam-based” metrology activities from METRO450 in Israel. SEMI invited their partners to share with attendees their insights, activities, and results in the preparation of future offerings of process equipment, materials, IT/fab automation systems, facilities and fab infrastructure, in order to rise to the challenge to ensure a continued economic manufacturing of state of the art semiconductor chips.

This year we exhibited as part of Silicon Saxony's Industrie 4.0 booth that consisted of about 40 kiosks representing companies with varying focuses within the industry. On Wednesday night, Silicon Saxony played host to all of the booth's exhibitors in a "Countries of Europe"-themed party. The event gave the Cimetrix team a chance to catch-up with friends and colleagues, and discuss new business opportunities. We'd like to thank Silicon Saxony for the great networking opportunity.

We are looking forward to SEMICON Europa 2016 in Grenoble, France next October and hope to see you there.
