Find the entire series here.Computer prices have plunged over the years even as desktop and laptop PC performance has skyrocketed thanks to the semiconductor industry, giving users much more bang for their buck. The chip industry stands in a stark contrast to healthcare and education with their exponentially rising costs.What distinguishes the semiconductor industry from healthcare and education in the capacity to deliver so much for so much less over time? After all, even in other parts of the technology sector that are heavily regulated, such as cable television, we have not witnessed the same price decreases as in microelectronics.Some pundits claim that the difference among sectors is tied to their degree of regulation. Does greater regulation somehow degrade product value? The reality is far more nuanced. But one thing is clear: Smart self-regulation (i.e. standards) in the semiconductor industry has contributed mightily to its success.The recipe for success has been simple. Standards have been rocket fuel for competition, which in turn has sparked innovation, driving down device prices while boosting performance. Computer prices fell dramatically between 1997-2015 while the cost of cable TV and internet services rose. Myth of unregulated competitionA semiconductor fab might actually be the most regulated place on earth. Fabs hew to a much higher standard of air quality and cleanliness than even uber-sterile hospital operating rooms. Manufacturing processes are voluntarily regulated not to millimeters, but to nanometers. While some standards are proprietary with limited reach, others span the supply chain. Regulation has worked so well in this sector that the semiconductor industry isn’t moving toward less standardization. It’s moving toward more. Secret is smart standards The gap between regulation and self-regulation is more like a chasm. We typically view regulation as a series of top-down directives that more often focus on the interests of the producer than the consumer. Healthcare regulation, for example, may improve quality of care, but it’s often insurers, big pharma and hospitals that benefit most from regulation, rather than consumers.The semiconductor industry, on the other hand, uses self-regulation to improve business operations and make better products for consumers. Falling prices and rising performance are natural byproducts.Semiconductor industry self-regulation is an ecosystem-wide effort, where input isn’t just top-down, but also bottom-up or even side-to-side. The first SEMI Standard, which specified wafer sizes, exemplifies this approach.The SEMI Standards Committee formed in 1973 to address silicon wafer dimensional specifications. At the time, wafer specifications proliferated. Numbering more than 2,000, the various specifications led to major inefficiencies just when the industry was just getting underway. Wafer suppliers banded together under SEMI to solve this problem and rapidly developed consensus specifications for 2- and 3-inch wafers. By the mid-1970s, over 80% of wafers conformed to these new standards.Standardized wafer sizes freed equipment companies to focus on innovations that reduced cost and increased performance. It also allowed manufacturers to focus on product differentiation without having to worry about device fabrication process and cost. Since that first SEMI Standard made possible the modern semiconductor equipment industry, original equipment manufacturers (OEMs) have competed to deliver amazing innovations. For example, lithography systems routinely use light to design chips with feature sizes smaller than the wavelength of light.SEMI’s 1000th standard on energetic materials demonstrates how smart standards are also pragmatic. This standard is not about banning materials or assigning blame when things go awry. It is about creating practical guidelines that companies will follow, enabling them to realize greater innovation. Guidelines that reduce accidents and risks will spur more, not less, energetic materials’ exploration. Industry suppliers will be the big winners.The 1st to the 1000th SEMI standard all represent examples of cooperation making more sense than competition.Standards for the real worldCreating a business-friendly standard that still gets the job done is a process. As SEMI Standards Task Force and Committee members, materials, equipment and manufacturing companies take part in defining best practice guidelines that support safe and practical use of materials and equipment. Task force and committee members assign particular responsibilities and associated costs to the most logical segments of the supply chain. They also develop information-sharing practices around competitive process recipes and purity standards.Andy McIntyre, CIH, a member of the energetic materials task force and an executive vice president and managing principal at BSI EHS Services and Solutions, summarized what makes SEMI standards smart.“SEMI standards are pragmatic,” said McIntyre. “They take into account the need for implementation in a real-world business environment. They embrace an engineering approach to problem-solving to create practical solutions, and they define specifications and performance goals in ways that allow engineers — in collaboration with EHS professionals — to identify practical solutions for reducing risk in R D, pilot line and manufacturing operations.“SEMI standards employ a holistic process that considers all the important points of view throughout the supply chain, from materials selection, installation, use, recycling and/or disposal,” said McIntyre. “The breadth of SEMI EHS Guidelines, for example, is also very comprehensive as the SEMI EHS Committee and task forces work to ensure that standards keep pace with dynamic technology developments. Energetic materials is a prime example where the industry recognized the need for a new safety guideline to document safe usage of pyrophoric, water-reactive and unstable reactive materials, which have become increasingly important in semiconductor and advanced materials R D and manufacturing.”This is the real secret to the success of the semiconductor industry. Smart self-regulation allows industry players to cooperate in the development and implementation of standards that are pragmatic, comprehensive and dynamic. Participants in SEMI Standards have a voice in the semiconductor industry because they are the voice of the semiconductor industry.While innovation in semiconductors may not always keep pace with Moore’s Law, we can depend on one truth: As long as collaboration and cooperation are the rule and not the exception, we will continue to advance technology in amazing and unprecedented ways. You, me and all other consumers will continue to reap the rewards of innovation. Use your voice to affect standardization in and around the semiconductor industry.

This article is the third in a series highlighting the vital importance of SEMI Standards to commemorate the publication of the 1000th SEMI Standard in July 2019. Find the entire series here.SEMI Standards are the bedrock of the modern microelectronics industry. Without standards for wafer dimensions – which SEMI Standards first defined through a collaborative process involving semiconductor manufacturers and wafer suppliers in 1972 – the semiconductor equipment industry as we know it would not exist today. The late Robert Noyce of Intel noted in this 1992 video “being good at producing semiconductors will mean we have better, more consistent, better controlled equipment than we have in the past. Standards are going to play a vital role in that. Standards saves money and time for everyone.” Noyce also called standards a bellwether to surges of innovation in critical process technology. This is still true today as, for example, important standards-setting activity is afoot in panel-level packaging, electron microscopy and energetic materials. Will a surge of innovation follow?Panel-level packaging: a chicken-egg scenarioFrom advanced materials to more efficient production tools, one hallmark of the microelectronics industry is our fearless exploration of new technologies that will spawn change across the industry by improving performance and reducing cost. Advanced packaging techniques, such as panel-level packaging (PLP) – which moves semiconductor packaging to a larger-panel format – is one of those critical catalysts. Citing PLP’s potential to shrink costs by improving efficiency and economies of scale, research firm Yole Développement predicts a remarkable 63% CAGR for PLP from 2017-2023.[i]It’s no stretch to say that we are close to realizing a burst of innovation in packaging. With a just-published SEMI Standard (SEMI 3D20) specifying panel sizes, equipment companies will find it economically viable to invest more in developing the much-needed production tools that enable PLP. “It is really important to create standards so we come together and work much more efficiently. Creating those fundamentals allows you to be more productive in the long term,” said Christina Chu, ASM Semiconductors, and co-leader of the Panel Level Packaging Task Force, and one of five industry leaders recognized for their outstanding accomplishments in developing SEMI Standards for the electronics and related industries at the recent 1000 SEMI Standards reception during SEMICON West 2019. “This effort came up from the trenches,” said Richard Allen, NIST Quantum Measurement Division, and a co-leader of both SEMI’s 3D Packaging and Integration Committee and its Panel Level Packaging Task Force. “Equipment vendors told us that they wanted to serve the market, but they couldn’t do so without some standards. To respond to their request, our committee surveyed the market and discovered at least 15 different panel sizes in development.”“As no vendor is going to make over a dozen unique tools for the same process, we worked with the manufacturers and tool companies to write a specification that standardizes on two of the most widely accepted sizes,” Allen said. “For the first time, the industry will have a real market for panel-level packaging tools, and that will spur commercialization of new technologies that never would have seen the light of the day without standardization.”Allen pointed out that evolution of standards in microelectronics reflects the dynamism of the microelectronics industry itself. “Given the rate of technology advancement in microelectronics, SEMI Standards committee and task force members know that a newly-published standard is often just a starting point, and change will likely follow,” he said. “The Panel Level Packaging Task Force, for example, is currently determining how to best support this packaging technology, whether through possible enhancements to 3D20 or by creating new PLP standards.”Process automation is key for TEMTransmission electron microscopy (TEM) is another area where industry cooperation will fuel progress.“People throw around the phrase ‘exponential growth,’” said James Amano, senior director, International Standards at SEMI. “It’s usually a gross exaggeration, but not when it comes to TEM data. That’s because demand for more TEM data, which uniquely enables innovations around smaller feature sizes, has exploded. At the same time, TEM data is a bottleneck in the fab. Operators literally use tweezers to carry around electron microscope samples by hand, and that is untenable.” TEM sampling standards are currently being formulated under the SEMI Standards development process. “Applying a model that we have employed successfully time and time again through SEMI Standards, we are gearing up for process automation in TEM,” Amano said. “We’ll start by establishing a grid carrier standard for electron microscopy. Through ongoing standards efforts, we may realize a fully automated TEM process within just a few years. That achievement will enable exponential growth in shrinking design geometries.”Energetic materials gain safety standardAlong with wafer-level packaging and design shrinks, the push for safety in materials’ usage is a hotbed of innovation. This is especially true with energetic materials, the potentially hazardous process chemicals used increasingly in semiconductor manufacturing to spur advances in materials purity, integrity and quality.“When you’re working with energetic materials, if you don’t get it right, you may face serious yield and cost issues, and most important of all, safety risks,” said Paul Trio, senior manager of strategic initiatives at SEMI. “This isn’t a theoretical concern. Real problems occurring in fabs have made an energetic-materials standard a high priority for the industry.”“After years of collaborating with companies across the supply chain to address this significant challenge, we recently published our 1000th SEMI Standard around safe usage of energetic materials,” Trio said. “Now manufacturers can turn to a new standard – which will evolve dynamically in response to industry changes – as they employ energetic materials in their quest to achieve higher yields while controlling costs and managing safety risks.” Whether it’s packaging, design shrinks, materials or other key innovations, standards are essential to progress in microelectronics. From equipment and materials suppliers that provide the most advanced, efficient and safest tools, materials, and processes to device manufacturers that get products to market, all stakeholders in the microelectronics ecosystem benefit from SEMI Standards.
