Tool Components/Parts

The manufacturing of integrated circuits free of micro-contamination drives the recent increase in demand for clean tool components (new and refurbished). Tool component manufacturers and cleaning vendors therefore highly benefit from the reliable analytical testing techniques that are critical to cleaning process monitoring and troubleshooting.

Traditional analytical techniques such as SIMS, AES, and EDX are considered acceptable for detection of inorganic and organic contamination on a 4"x4" coupon. However, these techniques cannot be relied upon to perform tests on actual parts and tool components due to:

  • limitation of analytical instrument chamber size. The reduction of component size is not only costly, but it can also add contamination.
  • low sensitivity in measuring contamination at levels required for 20nm technology and beyond.

ChemTrace offers solutions to the limitations of traditional analytical techniques. Our expertise in nondestructive techniques makes us the analytical lab of choice for many of the largest semiconductor tool manufacturers and integrated circuit fabs. Techniques we have developed are suitable for characterizing the cleanliness of coupons, surface finishes for new and used parts, and 200mm, 300mm, and 450mm tool components made from various materials.

Our expertise extends to correlating post-cleaned parts with wafer surface contamination after chamber processing, or after wafer contact with the cleaned surface. We establish cleaning specifications for tool parts by utilizing the Tool Specification Cycle, which is composed of cleaning the part, verifying the part's cleanliness, processing wafers using the cleaned part, and characterizing the wafer. Wafer contamination levels after IC processing are used as the benchmark to set the cleaning specification. The Tool Specification Cycle may also be used to identify and troubleshoot problematic parts that cause low MWBC (mean wafer between clean) or wafer contamination levels that do not meet processing specification.
