Resin Green
Resist materials for transition to green processing in semiconductor industry
Alternative (to mainstream Silicon CMOS technologies) semiconductor manufacturing process technologies able to sustain in the mid and
long-terms the fast pace evolution of device performance, miniaturisation and cost, while reducing environmental footprint. RESIN
GREEN proposes the development of new resist material platforms that can be processed under conditions offering clear advantages
regarding reduction of environmental footprint. In particular, new resist chemistries targeting to materials than can be processed
(deposited and developed) by using environmentally friendly solvents such as water, very dilute aqueous base solutions, or green organic
solvents. In this context we will develop new resist materials in order to eliminate the use of organic solvents and aqueous alkaline
solutions that are currently used in the lithographic process at semiconductor manufacturing industry. The lithographical process steps
that demand the major amounts of solvents are the spin coating solution of the photoresist as well as the development process. We target
to replace the standard organic solvents which are used in spin coating and the highly alkaline TMAH solutions used in development
with water. The use of greener organic solvents and very dilute basic developers will only be considered if necessary for meeting high
performance requirements. Our target is to investigate bio-source materials and new photoresist platforms suitable for exposure at 193
nm, 248 nm or EUV and achieve significant breakthroughs by designing a complete process, using renewable resources and neither
organic solvent nor hazardous chemicals. In addition, e-beam lithography will be considered, especially for evaluating the high resolution
potential of the proposed resist materials.
