Time: MWF 8:30-9:20 amOffice Hour: 10:00am-7:00pm anytime

Course Description: An examination of modern characterization techniques routinely employed to determine semiconductor material and device parameters.Concepts and theory underlying the techniques are reviewed, and sampleexperimental results are presented. Emphasis is on techniques employing electrical measurements.

Course Objectives: This course is intended for graduate students in MN and  related areas who are either i) interested in pursuing research in semiconductor materials, structures or devices, or ii) seeking the broad device background on the-state-of-the-art technologies for a future R&D career in the microelectronic industry. 

Fundamentals State-of-the-art

Teaching Philosophy for ECE 658

• Motto “Durch Messung zu Wissen”(German) “During or through measurement to

understand” (English)• The best way to learn ECE 658 is to

measure the devices in the lab and understand what you are measuring.

• 4 lectures + 2 hours (lab or discussion sessions) every two weeks
