claim 43 is sustained.
Appellants argue that "claim 44 of Applicant's invention
is directed towards a process that does not require a masking
material to be deposited on the substrate" (Br10) and the use
of a mask which does not contact the substrate is not

a mask deposited on the substrate; "imaging" still occurs even
though the mask is on the substrate. The rejection of
claim 44 is sustained.
