If organic contamination is your concern, then you may also want to look at UV-ozone cleaning, which removes organics at least as well as SC-1 and SC-2, and it is a dry cleaning method. Both methods are described in "Handbook of Semiconductor Wafer Cleaning Technology - Science, Technology and Applications," edited by Werner Kern, Noyes Publications, 1993. In simplest terms, in the UV-ozone method, short wavelength UV generates atomic oxygen and excites or dissociates the organic molecules which react with the atomic oxygen. The results are CO2, water, and other light molecules that desorb. ..............John. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> O John R. Vig, Ph.D. O U. S.

Author: Jason Tauscherat Internet_Gateway Date: 8/24/98 9:33 AM Someone mentioned a solution used to clean off Organic contaminants called RCA Etch or something similar. It was developed in the 70's or earlier, but I can't find any literature on it. I believe that it contains H2O2 and H2SO4 but I don't know in what proportions. If anyone can help me out, I'd appreciate it. We're having some problems with "sticking" of our capacitive accelerometers and want to eliminate the possibility of organic contaminants. Any suggestions would be appreciated. Thanks.
