The SAS Laboratory provides micro-analysis of high purity electronic materials to sub-ppb levels in order to identify and characterize trace contamination in organic and inorganic samples. Test results of are always checked for accuracy by duplicate sampling at different times and conditions. Our policy is to use internal spiking and and internal standards on different concentrations to confirm the accuracy of results.








The highly skilled staff in our R&D department analyzes test results to determine the root cause of yield loss from micro-contamination and other process related problems. SAS scientists work directly with the customer's process and equipment engineers to achieve the most cost effective solutions to their problem. SAS may request additional samples to complete their studies and, if needed, will collect and evaluate samples at the customer’s facility.

         SAS R&D is supported by a network of chemists, physicists, and engineers from academic institutions around the country. Depending on the nature of the assignment SAS is able to obtain expert advice to help solve virtually any problem.  

        Semiconductor Analytical Systems has performed many investigations into process issues related to semiconductor, solar and hard disk manufacturing.  For example, we have identified the cause of contamination on ceramic elements in a CVD reactor, investigated and solved a dry etch process problem, and helped to achieve uniformity in a chemical purification process.  SAS has successfully resolved these and many other process problems in a timely and cost-effective manner.

        We welcome the opportunity to help you.  Please contact us.
