Dear all, I am looking for extremely thin pyrex wafers of the order of 40um in thickness. I have done a search and found that the thinest commercially available pyrex wafers to my knowledge is about 300um in thickness. Please advise me the means to further reduce the thickness of pyrex wafers and as to whether it is worthwhile to do it. All help is greatly appreciated.
