Influence of controlled deposition rate on mechanical properties of sputtered Ti thin films for MEMS application

1 Introduction Titanium thin films have been widely used in different areas of semiconductor device technology because of their desirable mechanical properties, such as high hardness, good corrosion and wear resistance, metallurgical stability and seem to be the best replacement of polycrystalline Si in very large-scale integrated circuits [ 1 - 4 ]. For the development of new materials in MEMS application, in addition to their mechanical characteristics including high hardness and good elasticity, fine adhesion and low interface stresses may play an

Synthesis and characterization of polyimide thin films obtained by thermal evaporation and solid state reaction

-step reaction, as shown in Fig. 2 . We used pyromellitic dianhydride (PMDA) and p-phenylene diamine (PDA), commercially available from Sigma-Aldrich. These two monomers, 2 g each, were evaporated from two separate boats to form a poly (amic acid) (PAA) thin film on a substrate. The substrates used were silicon wafers and glass. The deposition process was carried out in vacuum of 2 × 10 –3 Pa. Fig. 1 shows the scheme of the PVD apparatus [4] . The resultant polyamic acid PAA film was then soft baked to remove the H 2 O from the substrate followed by a thermal treatment at
