- barrier material and hard baked photoresist material which has protected the conductive barrier
- the hard baked photoresist material is removed by contacting it
- Dense phase fluid in a liquid state is most conveniently used as a starting component, but
- pressure and temperature will depend upon which dense phase fluid is used.

- R protest R 2 , R 3 , and R 4 are substituents selected from the group of hydrogen, hydrocarbon
- R, R 2 , R 3 , and R 4 can be the same or different
- the cyclic ethers are generally considered more useful because there is less likelihood of
- Presently preferred dense phase fluid modifiers include, but are not limited to, propylene
- Dense phase fluid modifiers which are completely soluble in the selected dense phase
- photoresist polymer to the extent necessary for removal of the photoresist material is needed.
- supercritical phase of solvent is prepared by combining selected amounts of each of the
