This section of papers is a reconstruction of the basis for a departmental seminar 
I gave in the 1987-1988 timeframe (not sure of exact date) to the RPI Chemistry Department. 
The topic of the seminar was process and material for color cathode ray tube production. 
I had selected a few topics:
1) An overview of the CRT manufacturing process,pointing out the areas that had 
interesting chemictry content
2) A review of a project of mine on a modified polyvinylalcohol photoresist 
for the black matrix process used in screen production. This was my first patent. 
It ended up being used as the resist of choice in our tube plants from the early 1990s 
until the end of color CRT production as an industry.
3) A review of the chemistry involved in the RCA one piece cathode and the studies 
which showed how Cr froma nichrome metal layer diffused into the alkaline earth oxides 
that were the basis for the thermionic emitters used in color CRTs. This was based on 
the work of J.J.Maley and K.T.Chiang, who worked in the Materials and Process 
Development department I managed at teh time. Jim Maley was the lead for the group 
that was responsible for the backend processing.
4) A review of the chemistry and process used in the photochemical machining of 
various metals used in shadow mask manufacture. This was based on the work of J.J.Moscony,
R.B.Maynard and other co-workers. Jack Moscony was responsible for the Front end 
materials and process development in my organization

At this point in time I am putting 3 papers that cover the technical review of 
this material. My seminar drew from this information for the presentation.
Most of it was from information and material that was published and presented in 
the early 1980s. My photoresist paper was presented at the 157th meeting of the ECS 
in May,1980 in St. Louis. The work of Maley and Chiang and Moscony et al was published  
in the RCA Review in 1984 and the work of Moscony et al was published in several 
papers in the RCE Review and the RCA Engineer, mostly in 1984.

I am still working on a good presntation of the overview of CRT manufacture and 
will post it when available.
