6.1 Introduction

Ultrathin film is defined as having a layer thickness of less than 10 nm, whereas the thick layer is deemed to range from several tens to 100 µm. Ultrathin films are of particular importance in nanotechnology, while the latter are known in the field of microtechnology. However, “nano” is not a direct extension of “micro.” Microscale constructions could be achieved by miniaturizing existing fabrication techniques; nevertheless, similar methods may ...
