Syllabus

Course overview and goals

In this course, various bonding technologies, which are applied to highly reliable power modules for hybrid vehicles and so on, will be explained by showing the results of actual analysis. Students can learn importance of materials science in development of electronics devices.
This course in Tuesday class gives an overview of amorphous materials, mainly glass materials. Students can extend their knowledge on the fabrication techniques and characterizations of the materials. This course can give the special fabrication techniques and characterization not only for amorphous materials but also general information for various types of materials. The aim of this cause is to widen your knowledge about material research.

Course description and aims

By the end of this course, students will be able to:
1. Understand phenomena in bonding processes and bonding mechanism
2. Understand the evaluation of bonding to ensure the performance of power devices
3. Understand the analysis method for micro-structure using electron microscopy
4. Understand usefulness of materials science through practical power modules analysis data

By the end of this course, the students can obtain knowledges as follows;
1. fabrication techniques for glasses and glass sciences
2. characterization techniques for glass structures
3. fabrication techniques for amorphous materials
4. fabrication techniques for materials by chemical solution process

Study advice (preparation and review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Handouts will be distributed. It is recommended to bring a notebook computer with Windows OS, LAN or wireless LAN since thermodynamic calculation software and Microsoft Excel will be used in the course. Thermodynamic calculation software run only on windows OS will be installed into an individual PC. LAN or wireless LAN will be used to access a license server.
