Applied Ventures hosted the Sustainable Semi Venture Forum on September 23, 2021. The goal of this event was to highlight the sustainability needs and challenges of the semiconductor industry and identify how innovators and entrepreneurs can help achieve them. During the sustainable insights session, experts presented deep dives on the technical aspects of: • Semi industry lifecycle • Energy and water • Chemicals Topic: The Environmental Footprint of Logic CMOS Technologies (semi industry lifecycle) Presenter: Lars Åke Ragnarsson, IMEC Fabrication of integrated circuits is an energy and resource intensive process and the drive toward higher performance and increased functionality increases the process complexity dramatically from node to node. In this talk, we address the environmental footprint of CMOS technologies. We show a significant increase in the use of electricity (x3.5) and UPW (x2.3), as well as GHG emissions (x2.5) per wafer from iN28 to iN3. Topic: Energy and Water Presenter: Andreas Neuber, Applied Materials Topic: Sustainable Electronics - A Materials Supplier’s Perspective (chemicals) Presenter: Katherine Hutchison, EMD Electronics Global digitization will help reduce CO2 emissions through remote work, e-health, smart agriculture and industry 4.0. Materials innovation is increasing device energy efficiency, which further reduces their carbon footprint. However, semiconductor manufacturing processes use toxic materials and most waste is abated and discharged rather than recycled and/or repurposed. Furthermore, the electronics industry is generating more than 50 million tons of e-waste per year. The industry needs new technologies that enable materials waste to be captured, purified and recycled or repurposed, instead of relying on “virgin” materials in our supply chain. An ecosystem needs to be established which facilitates a circular electronics materials economy for both new and existing fabs.
