This course introduces students to the basic concepts of shaping materials and their impacts on properties and structure. An introduction to the fundamentals of diffusion in a solid follows. We present different types of diffusion mechanisms and their dependence on temperature. The role of dislocation on mechanical properties and how it can be used to strengthen materials will be shown.

Syllabus
- Shape and Property Control of Metals I & II
- This course introduces students to the basic concepts of shaping materials and their impacts on properties and structure. An introduction to the fundamentals of diffusion in a solid follows. We present different types of diffusion mechanisms and their dependence on temperature. The role of dislocation on mechanical properties and how it can be used to strengthen materials will be shown.
- Module 1: Diffusion and Its Mechanisms
- In this module, we explore shape and property control of materials and diffusion of atoms into different materials.
- Module 2: Diffusion
- In this module, we explain how physical (e.g. atom size; host atom bond strength) factors affect diffusivity and activation energy.
- Module 3: Shape and Property Control of Materials
- Semiconductor devices require very precise control of the properties of the materials that are used for the devices. In this module, we learn about shape and property control of materials, dislocations, and strengthening mechanisms.
- Module 4: Strengthening Mechanisms
- Metal alloys are used for interconnections (and for chip-substrate joins) in semiconductor technology. Strengthening mechanisms are used to enhance the strength and reliability of such interconnects. In this module, we discuss the different kinds of strengthening mechanisms for metals and their alloys.
