Environmental Regulations: Semiconductor

For more than 25 years, Trinity Consultants has assisted facilities in the semiconductor industry with regulatory compliance and environmental management. Trinity takes pride in understanding not only the regulatory requirements affecting our clients’ facilities, but also in understanding their industry and processes, the challenges that may be unique to that industry, and that time-to-market and wafer cost are important to the semiconductor industry. Our consultants enhance their knowledge of the semiconductor industry through our work with recent and ongoing projects. We have over 80 semiconductor clients and have completed nearly 300 projects for semiconductor facilities, giving Trinity the expertise to assist your facility with its environmental compliance needs.

Environmental Regulatory Round Up

Toxic Release Inventory (TRI) Reporting is due July 2015 for reporting year 2014. EPA expects complete, detailed threshold determinations to show whether reporting is needed for all non-exempt activities for TRI chemicals at a wafer fab facility. Process byproducts need to be determined. For example (1) hydrogen fluoride from fluorinated greenhouse gases used in chemical vapor deposition (CVD) chamber cleans and plasma etch processes; (2) fluorine from use of nitrogen trifluoride (NF3) in CVD remote plasma chamber cleans; and (3) ozone made in ozone generators from oxygen. Another important threshold determination is for sulfuric acid aerosols and hydrochloric acid aerosols. These aerosols can be generated from spraying these acids in spray processes, wet scrubbers, and evaporation from use of these acids.

Environmental Project Profiles: Semiconductor Facilities

  • Trinity has supported dozens of fab-wide exhaust management and point-of-use (POU) abatement device strategies.
