Learning Outcomes (valid 01.08.2018-31.07.2020): 

The main focus of the course is placed on understanding the materials compatibility in heterogeneous structures utilized in smart system integration and ubiquitous electronics. After the course the student can utilize a method combining thermodynamics and reaction kinetics of materials, theories of microstructures, mechanics of materials as well as mechanisms of adhesion to solve materials compatibility issues in electronics and microsystems. The student understands the thermal, thermomechanical and mechanical properties of materials used in electronic products from reliability point of view and how these properties can be controlled. In addition, the principles of finite element modelling will be comprehended.

Content (valid 01.08.2018-31.07.2020): 

The basics of materials compatibility, chemical reactions between materials, interfacial phenomena and their effect on the material properties. The interpretation of phase diagrams, diffusion mechanisms and microstructures of real cases from microsystems integration. The mechanical, thermal and thermomechanical characterization of microsystems. Modelling tools, principles of reliability mechanics and materials behavior under different stresses. A brief training of finite element software (Abaqus) about thermomechanical simulation.
