By the way, so far the exposure is about 120 to 130 mj on the asml
for,. I will post the pictures on my office door for now as I did not
get a chance to go through them and organize them.

Hello all,
Here some preliminary result of the new I line resist for ASML stepper
The resist is shipley SPR955cm-.7.
I am attaching a spin speed curve and another chart with more details
measurement ( 5 points).
The soft bake temp. for all of these tests are done 120 second at 90C
on the SVGcoat.
I have done E0 test on the asml and I see the best thickness for the 955
resist at .9 to 1 um.
All these tests need to be repeated at least one more time but for now
should do for some of you whom wants to get in there and run the system.
I have updated the sheets next to the svg coat and SVG developer with
the correct recipes:
Recipe #5 for the svgcoat ( front track only)
Recipe #2 for the SVGdev and SVGdev2
Please note that the new developer has surfactant and is called Shipley
MF26A.
Thank Uli for helping with upgrading the paper work.
I will put a copy of the spin speed curve in the RED LItho Binder.
Please note that shipley 3612 still can be used but we will not be able
to push the resolution behind .6 um. To my surprise the exposure is very
fast, minimum exposure on the ASML is 40mj and we have been exposing it
at 45mj.
