Optical and X-Ray Characterization (Coursera)

Offered by Arizona State University,

Optical and X-ray techniques are powerful ways to characterize semiconductor thin films. They can be used to measure film thickness, purity and crystalline quality, and for compositional analysis. Modern techniques are fast, turn-key, and generally non-destructive, allowing for rapid assessment of material properties. This course describes the fundamentals of optical and X-ray characterization and provides real-world examples of how they are used in semiconductor manufacturing.

Course Introduction
Optical and X-ray techniques are powerful ways to characterize semiconductor thin films. They can be used to measure film thickness, purity and crystalline quality, and for compositional analysis. Modern techniques are fast, turn-key, and generally non-destructive, allowing for rapid assessment of material properties. This course describes the fundamentals of optical and X-ray characterization and provides real-world examples of how they are used in semiconductor manufacturing.

Week 5.1: Reflectance Spectroscopy
This week introduces the concept of reflectance spectroscopy: a rapid, convenient, and non-destructive technique for measuring the thickness of transparent materials.

Week 5.2: Ellipsometry
This week, you will learn about ellipsometry, a powerful technique that allows us to extract the thickness and refractive index of transparent layers as thin as a few nanometers.

Week 5.3: Photoluminescence
This week, you will learn about photoluminescence.

Week 5.4: Electron Microprobe X-Ray Analysis
This week, you will learn about electron microprobe X-ray analysis.

Week 5.5: Course Wrap-up and Project
This week, you will complete a case study to assess your ability to analyze electron microprobe x-ray images to determine the constituent elements in a 40 nm MOSFET.

Materials Science: 10 Things Every Engineer Should Know (Coursera)

Engineering Sci: Chemistry

We explore “10 things” that range from the menu of materials available to engineers in their profession to the many mechanical and electrical properties of materials important to their use in various engineering fields. We also discuss the principles behind the manufacturing of those materials. By the end of the course, you will be able to: recognize the important aspects of the materials used in modern engineering applications; explain the underlying principle of materials science: “structure leads to properties,”; identify the role of thermally activated processes in many of these important “things” – as illustrated by the Arrhenius relationship; relate each of these topics to issues that have arisen (or potentially could arise) in your life and work.
