Polyimides are known as good insulators with high thermal stability for microelectronics. Ultrathin films of polyimides were obtained by the LB technique [306,307]. The film was almost pin-hole free with a smooth surface [308] and the conduction mechanism in MIM (metal-insulator-metal) configuration was examined [309]. An electrical memory switching phenomenon was also observed in polyimide LB film incorporated in MIM devices [310]. 

The Parylene conformal coatings are ultrathin, pinhole-free polymer coatings that provide a number of high-value surface treatment properties, such as, excellent moisture, chemical and dielectric barrier properties, thermal and UV stability, and dry-film lubricity. These properties make Parylene coatings the ideal choice for a number of industrial applications throughout the medical device, electronics, automotive, military, and aerospace industries. Some examples are listed [155].
