Abstract

In recent years, polyimide film has become a commonly used insulator for microelectronic devices including advanced semiconductor chip and high density packaging. It has the advantages of low dielectric constant, thermal stability and low processing cost. In general, it is important to understand both the thermal and mechanical properties of a microelectronic material. Thermal and mechanical properties play very important roles in terms of determining the device structural integrity. Mismatch of material properties could cause feasibility and reliability problems. These properties are also essential for mechanical stress and thermal stress modeling studies. Biphenyldianhydride-Phenylenediamine (BPDA-PDA) and Pyromellitic Dianhydride-Oxydianiline (PMDA-ODA) are two commonly used polyimide films in electronic industry. Their thermal expansion coefficients and mechanical properties were studied and reported here.
