Nanostructured Anodic Al2O3/TiO2/Al2O3 Metal–Insulator–Metal Capacitors
This paper presents the fabrication of Al2O3/TiO2/Al2O3 metal–insulator–metal (MIM) capacitor using anodization technique. High capacitance density of > 6 fF/μm2, low quadratic voltage co-efficient of capacitance of <103 ppm/V2 and a low leakage current density of 4.3 × 10–11 A/cm2 at 3 V are achieved which are suitable for analog and mixed signal applications. The structural and electrical properties are discussed in detail. This work suggests that the anodization method can offer multilayer crystalline dielectric stack required for high performance MIM capacitor.
