Diamine Monomer

Novel polyimide–copper complexes (PICuCs) were prepared by polymerization, complexation and imidization of a newly synthesized bipyridine-containing diamine monomer. They showed high dielectric performance, and excellent mechanical and thermal properties.

High Dielectric

Lead zirconium titanate films (Pb (Zr,Ti) O3 or PZT) are being considered for potential application as dielectric films in memory technology due to their high dielectric constants. PZT is a ferroelectric material which shows spontaneous polarizability, reversible under applied electric fields. We report herein some results of TEM studies on thin film capacitor structures containing PZT films with platinum-titanium electrodes.The wafers had a stacked structure consisting of PZT/Pt/Ti/SiO2/Si substrate as shown in Figure 1. Platinum acts as electrode material and titanium is used to overcome the problem of platinum adhesion to the oxide layer. The PZT (0/20/80) films were deposited using a sol-gel method and the structure was annealed at 650°C and 800°C for 30 min in an oxygen ambient. XTEM imaging was done at 200KV with the electron beam parallel to <110> zone axis of silicon.Figure 2 shows the PZT and Pt layers only, since the structure had a tendency to peel off at the Ti-Pt interface during TEM sample preparation.

High Dielectric

A novel high dielectric constant all-organic polymer film of a copper phthalocyanine oligomer grafted to polyimide (CuPc–PI) was successfully synthesized via a polycondensation between a copper phthalocyanine anhydride oligomer and amino-capped polyamic acid, followed by thermal treatment.
