Abstract: A novel method for electrically measuring the thermal expansion coefficient of polysilicon thin films is presented.A thermal-electro-mechanical compliant model of the polysilicon thin film is established.Finite element software Coventor and ANSYS are used to verify this method.This method is convenient,and its output is in the form of an electrical signal.Thus,it is valuable for in-situ measuring the thermal expansion coefficient of polysilicon thin films
Key words: thermal expansion coefficient, polysilicon thin films, electrical measurement, pull-in
