Dear Birck Researchers, We have welcomed many new users to our community in recent weeks, from new graduate students to undergraduate students taking the popular courses on semiconductor processing and packaging. This is fulfilling our vision for "Innovation" and "Education," and we are pleased to support these programs to their fullest. One issue that has surfaced is higher use of chemicals that comes with having additional users. We have observed a much higher use of chemicals, especially solvents and developers, that support this additional processing. Also, our observations indicate that more researchers are using full 4" wafers and fewer coupons, which requires additional chemical use. We would like to ask our research community to conserve the use of chemicals, and only use the amount needed for the process. We've seen a few cases where a large beaker was 80% full just to process one wafer at the bottom. This is wasteful and expensive, so please be aware and use only the minimum amount of material that you need for the process. In the meantime, we're also reevaluating our order quantities and will increase our orders as appropriate. Thanks for your attention to this! Ron
