Title: Etienne Rognin: Innovator in Thin Film Technology
Introduction
Etienne Rognin is a notable inventor based in Le Havre, France. He has made significant contributions to the field of thin film technology, holding two patents that showcase his innovative approaches. His work primarily focuses on methods for obtaining structures through reflow and determining the viscosity of thin films.
Latest Patents
Rognin's latest patents include a method for obtaining at least one structure approximating a sought structure by reflow. This method involves predicting the progression over time of the geometry of an initial structure subject to reflow. It aims to compute correlation values of the geometry of each predicted structure with respect to the sought structure, ultimately identifying reflow parameters that yield the highest correlation value.
Another significant patent is a method for determining the viscosity of thin films, particularly polymer resins above their glass transition temperature. This method includes forming a thin layer of material on a substrate, impressing a known geometrical pattern, and measuring the topography of the impressed pattern before and after baking at a specific temperature. The mathematical processing of these measurements allows for the deduction of viscosity values at the measurement temperature.
