Contemporary thin film research and applications Chap.1 : Introduction 1.1 Applications 1.2 History 1.3 Process step 1.4 Examples 1.1 Applications • Why thin film ? Thin films are deposited onto bulk materials (substrates) to achieve properties unattainable or not easily attainable in the substrates alone. • What properties are required for the application at hand? Thin-film property Typical applications category Optical Reflective/antireflective coatings; Memory disks Interference filters; Waveguides; Metamaterials Electrical Insulation; Conduction; Semiconductor devices; Piezoelectric drivers Magnetic Memory discs Barriers to diffusion or alloying ; Chemical Protection against oxidation or corrosion; Gas/liquid sensors Mechanical Hardness, Adhesion, Micromechanism (MEMS) Thermal Barrier layers; Heat sinks Thin-films discussed in this lecture are: (1) from vapor phase deposition (2) contrary to thick films Comparison between thin and thick films Thin films: deposition of single molecules Thick films: deposition of partic
