7 Areas of Research Nanotechnology Semiconductor Materials CMP (Chemical Mechanical Planarization) Biomedical Materials Particle Science and Technology Smart Textiles Smart Surfaces

8 Materials and Characterization Laboratory _Particle Size Analyzer Surface Analysis: SurPASS Contact Angle Goniometer Atomic Force Microscope Sample Prep Area Chemical Mechanical Polisher_

9 Nano-Scale Protective Oxide Films for Semiconductor Applications & Beyond Help define design rules for new CMP slurry and processes by characterizing the chemically modified thin films. Material removal rates Defectivity control Selectivity Time windows Apply results to other applications where self protective oxide films are used. Chip packaging (self protective Al-oxide on contact pads highly reduced corrosion due to moisture led through the plastic material) Bio-implants (CMP creates self protective Ti-oxide films on implants while cleaning impurities ) Reactors/ Interfaces/ Thin films

10 Chemical Mechanical Planarization Process Advantages Disadvantages Source: Variables in CMP Operations Input Operational Output Surface to be polished Polishing Slurry Polishing Pad Applied Load Rotational Velocity Slurry Flow Rate Pad Conditioning Polishing Rate Defectivity Range/Uniformity Post CMP Cleaning

11 Controlled Modification of the Surface Properties of Biological Implants Success of an implant placement is determined by its integration into the tissue surrounding the biomaterial. Surface roughness and composition are considered to influence the properties of adherent cells. Infection is the main risk on the biomaterials used. Dental implants Cardiac pacemakers Orthopedic devices Titanium and titanium alloys are favored bio-implants due to their surface characteristics which promote biocompatibility.
