The subject matter of thin-films - which play a key role in microelectronics - divides naturally into two headings: the processing / structure relationship, and the structure / properties relationship. Part II of 'Materials Science in Microelectronics' focuses on the latter of these relationships, examining the effect of structure on the following: *Electrical properties*Magnetic properties*Optical properties*Mechanical properties*Mass transport properties*Interface and junction properties*Defects and properties- Captures the importance of thin films to microelectronic development- Examines the cause / effect relationship of structure on thin film properties
