Abstract

The first reports of this phenomena that I found was from about I960. In 1978 in one of the references that you'll find in the printed version of this, are some patents on some amine containing salts. These salts, when doped into positive resist, produce image reversal from positive to negative when it was exposed. In 1982 a paper given by a group at IBM at one of the Kodak Interface Symposiums talked about this in detail, trying to demonstrate what they thought the mechanism was of how this miraculous phenomenon worked.
