What Is Tribology?

Tribology, derived from the Greek word "tribos" meaning rubbing, is the science and engineering that deals with friction, wear, and lubrication of interacting surfaces in relative motion. It encompasses various aspects such as surface roughness, contact mechanics, adhesion, and lubrication mechanisms. The study of tribology has significant applications in various industries, including manufacturing, automotive, aerospace, and nanotechnology.

Importance of Tribology in CMP

Chemical Mechanical Planarization (CMP) is a vital process used in semiconductor fabrication to achieve a flat and smooth surface. It involves the simultaneous action of chemical reactions and mechanical abrasion to remove excessive materials and planarize the wafer surface. Tribology plays a crucial role in controlling the interactions between the wafer, polishing pad, and slurry during CMP. Understanding tribological phenomena helps optimize polishing parameters, reduce defects, improve material removal rates, and enhance overall device performance.
