Project Nanomechanical deformation of a flexible indenter tip Program Mechanical Engineering Undergraduate Research Program Term Spring 2026 Status Closed Research Area Mechanics, nanotechnology Description A sharp tip can be used to probe the local structure and properties of semiconductor devices. However, complex mechanics such as stick-slip friction, adhesive forces, and mechanical instability can complicate these tip-based measurements. In this project we will investigate the mechanics of a flexible sharp tip as it interacts with the sidewall of a photoresist material. Experiments measuring the force will be performed across a range of measurement conditions. A combination of contact mechanics, Euler Bernoulli beam theory, and finite element analysis will be used to build models of tip behaviors. The goal of this project is to better understand the various mechanical responses of the tip in order to improve our understanding of tip-based metrology used during semiconducting manufacturing processes.
