Microfabricated Structures for the Measurement of Adhesion and Mechanical Properties of Polymer Films.

Abstract

Microfabricated test structures for the in-situ measurement of adhesion of thin films have been described. Young's modulus and residual tensile stress are determined from pre-peel measurement of the load-deflection behavior of suspended membranes. On systems of weak adhesion, a blister test using suspended membranes has been carried out. For systems of good adhesion, an island test structure has been developed allowing even thin films to be tested. Mechanical models for all three structures are described. Keywords: Polymer, Polyimide, Mechanical properties, Adhesion, Film, Microfabrication, Stress, Modulus, Blister test, Critical pressure, Peel.
