In the beginning, GCA had some of the original
track systems developed for the industry after they acquired IMS and
made it a division at the same level as the photo repeater. Steppers
were still in the future and no track system was equipped with
software and hardware hooks so as to interface with the aligner. The
pieces just stood alone, often in their own sealed room —a prebake
here, a postbake over there, while the spinner sat in the middle,
which was just as good as it spewed resist everywhere, gumming up
the works and all around it. So when this system emerged, about the
same time as competitive systems from others, it was a substantial
improvement, though gummy resist remained the perpetual problem.
