KurzbeschreibungThe core of this course explains how the behavior of materials changes, when their external dimensions become small (usually on the micro- to nanometer length scale) until quantum effects become dominant. This is illustrated by examples from all materials classes and further substantiated by case studies of applications ranging from micro- and nanoelectronics to optoelectronics.
LernzielTeaching goals:

to learn which materials are used in electronics, microelectronics and optoelectronics and why

to understand how materials properties change when their external dimensions approach the micro- and nanoscale

to grasp the materials and processing issues involved in miniaturized electronic, mechanical and optical systems

to be exposed to state of the art technologies for fabrication and characterization of such systems
InhaltThe core of the course is the materials behavior in small dimensions. Focus will be put on scaling of electronic and mechanical properties, thin film mechanics, device reliability and integration issues when dissimilar materials are joined. Advanced characterization techniques specific to microcomponents will be presented. Finally possible future solutions to further miniaturization, such as carbon nanotubes or 3D integration molecular electronics, will be critically discussed. Excursions to microelectronic companies are part of the course.

Topics include:

Scaling laws and size effects
Energy scales in materials science
Length scales in materials science
Size-dependent color effects
Mechanical properties
