sustainability

As more than 400 speakers took the stages at SEMICON West 2024, sustainability and workforce development stood out as two major focus areas. The second day of this year’s CEO Summit keynote program, themed Seizing the Global Opportunities and Challenges Ahead, featured sessions on both topics. One of the first sessions of the day was the Chief Sustainability Officer (CSO) panel discussion, titled Bracing for the Evolving Global Risk for the Semiconductor Ecosystem, moderated by Vice President of SEMI Global Sustainability Programs, Dr. Mousumi Bhat. Later that morning, Shari Liss, Vice President of SEMI Global Workforce Development Programs and Executive Director of the SEMI Foundation, moderated a fireside chat, Advocating for Real Change: Why Inclusion and Belonging Need to be Everyone’s Concern, with Sandra Mahadwar from KLA Corporation. Bhat and Liss were later interviewed for a podcast by Francoise von Trapp of 3D InCites to share additional insights on sustainability and workforce development, respectively. Bhat was also joined by Paul Kelly, COO of the New York Center for Research, Economic Advancement, Technology, Engineering, and Science (NY CREATES). Creating a More Sustainable Semiconductor Industry During their interview, both Bhat and Kelly emphasized that the industry will need to reduce its use of per and polyfluoroalkyl substances (PFAS) to sustainably innovate at today’s nanometer pace. For this reason, Kelly highlighted the importance of learning to balance current production demands with the health of climate.To achieve this balance, they discussed the efforts of the Semiconductor Climate Consortium (SCC). Much of the SCC’s efforts, they said, will focus on driving the industry toward net zero emissions. SEMI and NY CREATES announced a memorandum of understanding (MOU) at SEMICON West 2024 to promote sustainable practices within the industry, with a focus on PFAS reduction. Kelly pointed to the ability of SCC members to test new materials, gases, and chemicals at NY CREATES’ R D facilities in upstate New York to work toward replacing PFAS with more sustainable alternatives. Bhat also shared that this collaboration helps facilitate prototyping, experimentation, and tests and measurements for newer, more sustainable substances.Dr. Mousumi Bhat of SEMI and Dave Anderson of NY CREATES celebrate their organizations’ sustainability MOU at SEMICON West 2024.“The thought leadership comes from the Consortium, and the support on infrastructure comes from NY CREATES,” said Bhat. “This should become a blueprint to solve some of the challenging problems that we have in our industry.” When it comes to reducing emissions, Bhat mentioned two key objectives. The first, she said, is access to clean energy, and the second is the reduction of greenhouse gases. Bhat cited these as the issues that will take the longest for the industry to solve and pointed to the importance of industry collaboration and partnerships to support the needed experimentation. But while partnerships will bring the industry closer to net zero, both Bhat and Kelly cautioned that it won’t be reached overnight. “Much more needs to be done in the industry to reach that net zero goal,” said Kelly. “New chip technologies, new chemicals, and new processes are very much large leaps to achieving that. But right now, even some of the most advanced will only reduce [emissions] by 70%.” To help bridge this gap, Bhat encouraged others to join and participate in the SCC. “Rather than everybody doing a one-to-one experimentation in their own space and spending those resources, I would like to invite anyone that's not part of the climate consortium,” she said. “And [I invite] those that are part of the climate consortium to engage more actively, so that we are all accelerating the journey toward net zero.” Addressing the Talent Shortage This year’s SEMICON West also featured five keynote sessions dedicated to workforce development, as well as a Workforce Development Pavilion that included several talks around diversity, equity, inclusion, and belonging (DEIB). With the estimated one million jobs the industry will need to fill by 2030, Liss shared that every role is needed – from entry level all the way to Ph.D. researchers. “We need to try and bring in as many people as we can over the next few years,” said Liss. “The talent shortage is a global issue, not just a U.S. one.” Shari Liss of SEMI moderated the fireside chat at SEMICON West 2024 with Sandra Mahadwar from KLA Corporation.To begin to close the talent gap, Liss stressed the importance of educating children about the semiconductor industry. “We are just invisible to kids,” she said. “In every part of the globe, they carry chips in their hands all day every day, and they don’t know. So to me, breaking that barrier and making sure kids know about our work as an industry is going to be so critical to making this successful.” Liss also highlighted differences in workforce development programs across the world, noting that what works in one region may not translate to another. For example, apprenticeships are widely embraced in Europe, she said, but they’re a fairly new practice in the U.S. Conversely, she shared that veteran-focused programs wouldn’t work for some regions, but they’re a “powerful win” in the U.S. Each SEMICON show across the world, she shared, includes similar workforce development and DEIB programming, in addition to targeted sessions for students and HR professionals. Companies can interview for open positions at SEMICON shows as well.

Per- and polyfluoroalkyl substances (PFAS) are a large class of thousands of synthetic chemicals that are used throughout the semiconductor industry in the form of gases, liquids, and solid high-molecular weight polymers, due to their wide range of physical and chemical properties. PFAS contain carbon-fluorine bonds, which are one of the strongest chemical bonds in organic chemistry, allowing them to resist degradation and to cover long distances away from the source of their release.In recent years, the high persistence of PFAS in both the environment and the human body has encouraged the European Chemicals Agency (ECHA) to launch a PFAS restriction proposal aiming to regulate and eliminate their use over the next few years. The proposal is currently under assessment by ECHA’s scientific committees for Risk Assessment (RAC) and for Socio-Economic Analysis (SEAC).PFAS in the Semiconductor Industry The exceptional physiochemical properties of PFAS provide them a high degree of functionality in semiconductor manufacturing across the entire supply chain, and often the combination of their properties allows manufacturers to satisfy multiple and overlapping technical requirements.While the industry recognizes the importance of transitioning away from PFAS, and research to that effect is ongoing, current technological limitations do not allow the industry to manufacture semiconductors without the use of PFAS or to discover scientifically viable alternatives that can effectively substitute their use.At this point in time, no known alternatives exist for most of the uses of PFAS by the semiconductor industry. Alternative substances must be researched, invented and potentially applied into mass production to be recognized as viable alternatives. Many different pathways will have to be explored as PFAS are currently used across the entire supply chain for over 1,000 semiconductor applications, including articles, support equipment and fab operations, or as process chemicals.SEMI Europe—European Semiconductor Industry Association (ESIA) PFAS Research Workshop Considering the criticality of the PFAS issue for the semiconductor industry, SEMI and the European Semiconductor Industry Association (ESIA) have greatly strengthened their joint advocacy efforts over this past year concerning the ECHA’s PFAS restriction proposal.In this regard, SEMI and ESIA successfully organized a workshop in October 2023 with the relevant representatives of the European Commission (DG GROW, DG ENV, DG CNECT and DG RTD) to present and discuss in-depth the key technical evidence for the use of PFAS is the semiconductor sector. The discussions built upon the extensive technical evidence that was presented by SEMI and ESIA in their respective submissions for the six-month PFAS consultation facilitated by ECHA.Following the successful execution of this first workshop, there was a keen interest from the European Commission to enquire further upon the current state of play of research and development efforts in the field of PFAS detection, abatement, capture and destruction, circularity, recycling and alternativesFor this reason, after the first workshop, ESIA and SEMI collaborated to develop and deploy a joint PFAS Survey aimed at identifying the research priorities in PFAS from the perspective of their member companies. Based on the survey outcomes, the associations compiled the SEMI–ESIA PFAS Research Roadmap and officially presented it to the representatives of the European Commission during a follow-up workshop on 13th June 2024. Discussions at the workshop focused on the key research priorities for the semiconductor industry to discover potentially viable alternatives to the use of PFAS. In the upcoming legislative period, SEMI Europe will continue to engage with relevant stakeholders to contribute to the political debate and encourage a legislative framework that can enhance sustainability across industrial supply chains while preserving Europe’s technological competitive advantage.
