VISION

In 1996, the NSF/SRC Engineering Research Center (ERC) for Environmentally Benign Semiconductor Manufacturing was created as a result of a joint initiative between the University of Arizona (lead institution), the  Massachusetts Institute of Technology, Stanford University, and the University of California-Berkeley with co-sponsorship from the National Science Foundation (NSF) and the Semiconductor Research Corporation (SRC).  The ERC's goal was to create the science, technology, and educational methods needed to lead the semiconductor industry to a new era of environmentally benign manufacturing.  When the ERC "graduated" from the NSF's Engineering Research Center program in 2006, the ERC continued under sponsorship of the SRC jointly with SEMATECH/ISMI (2006-2011).  The ERC has continued its partnership with the Semiconductor Research Corporation (SRC) throughout, and continues its firm commitment to developing its goals and objectives.

GOALS AND OBJECTIVES
  • Develop novel strategic solutions to existing environmental, safety and health (ESH) problems in semiconductor manufacturing.
  • Create new and effective environmentally benign manufacturing processes.
  • Demonstrate the positive impact of design for environment on all aspects of semiconductor manufacturing
  • Develop innovative education programs in which environmental factors are integral parts of the curriculum.

    Our specific objectives for achieving these goals were to:
     
  • Develop a methodology for incorporating Environment, Safety & Health (ESH) factors as design parameters in the development of new processes, tools, and protocols for semiconductor manufacturing.  The emphasis is on an "integrated approach," where interactions among processes are considered, and on "process optimization" for waste minimization. rather than relying on abatement and "end-of-the-pipe" treatments.
  • Demonstrate this methodology by applying it to selected manufacturing process groups that are of significant ESH concern.
  • Integrate the Center activities with academic programs to provide unique learning opportunities for undergraduate and graduate students
  • Extend the education mission to include continuing education and short courses for those in industry who wish to update their training in this area, and outreach to high school teachers to improve science and math instruction and make teachers aware of employment opportunities in the environmental and semiconductor industries.
  • Provide a technical forum for experts from industry, research institutions, and government agencies to exchange ideas and information on ESH concerns in semiconductor manufacturing.  These exchanges will be on a proactive, preventive, non-regulatory, and pre-competitive basis.

RESEARCH STRATEGY AND ORGANIZATION

lab1.jpg (84847 bytes) Environmental factors are often not included in the design and development of new tools and processes in the semiconductor industry. Integrating Design For the Environment into new processes and tools for the industry is the technical driver and the common theme of the Center’s research.  The Center’s interdisciplinary research efforts involve 14 universities and 11 different academic disciplines.

The semiconductor industry is a very fast-moving industry, one which creates many opportunities for innovation and implementation of changes. The fast pace also presents a major challenge in planning and conducting long-term research. One challenge is to strike the right balance between long-term development, short-term relevance, and application to the present problems. The Center’s research strategy is to maintain this balance and promote a mix of projects and activities ranging from high-risk, high-payoff research to smaller projects with more immediate applications.

Originally organized in thrusts built around semiconductor manufacturing processes [Thrust A (Back-End Processes), Thrust B (Front-End), Thrust C (Factory Integration), and Thrust D (Patterning)], the ERC's current core research and customized projects are listed below. 

Annual reports, interim research reports and annual review meeting materials are also listed below, and are available to SRC and ERC members only; these materials are password protected, privileged information and not for distribution.  If you have  questions regarding the annual report/review information, contact Karen McClure at (kmcclure@erc.arizona.edu).  SRC members can also accessed ERC research information via the SRC website: http://www.src.org.
