- Characterization of monomers and polymers by spectroscopic (1H-, 13C-, 29Si-, 31P-NMR, FTIR, MS, UV-VIS, DSC, TGA) and chromatographic (GPC, GPEC, GC) methods.
- Complex CMP slurries based on nanoparticles (silica, alumina, ceria, etc) for advanced nodes IC: metals (W, Ti, TiN, Ta, Ru, Cu) and dielectrics (TEOS, low K, ultra low K, etc.)
- Stable particles and polymer colloidal dispersions, synthesis, characterization and applications as CMP slurry formulations.
- Understanding particles/surfactants interactions below and above cmc.
- Surface energy (contact angle) measurements on hydrophobic and hydrophic coatings, metal and dielectric wafers, mar and scratch tests, formulation of coatings compositions and aqueous polishing slurries.
- Understanding structure-properties relationships and interfacial interactions in multi-layered coatings, particles/polymers surfaces in nanoparticles complex dispersions and slurries.
