EE732 Microelectronics

Objective of the course

To familiarize you with the modeling and the physical concepts behind the operation of microelectronic devices and enhance your appreciation for the field of high performance, high speed semiconductor devices used in VLSI systems.

Structure of the course

This course will help you think about the design, performance and limitations of devices. There is no single text book for this course. While the traditional texts are used only for reference, most of the material in this course is based on recent literature. You are expected to participate in the class not only in terms of raising questions and answering them but also in terms of applying what you learn to contrived and real world problems.

Exam Policy and Grading

There will be 2 Minor exams and 1 Major exam.  In all the exams, you are allowed to bring one A4 sheet on which you can write any formulas you think are important.

Marks Distribution

20 % - Minor-I
25 % - Minor-II
40 % - Major
15 % - Presentation

Seminar on Advanced Topics Format for the Term paper Click here

For the Seminar, you have to find a paper related to   Nanoelectronic Devices and Technology from the recent issues of IEEE Transactions on Electron Devices  or related journlas. You should submit  a clear and concise report(5-10 typed pages) based on the chosen paper and the related references by 25 October   2004.  No late submissions will be permitted. You will give a 15 minute presentation based on your report on 30 (Sat) and 31 (Sun) of October 2004. Attendance in the Seminar is a must for all the students.

Your feedback is valuable:

Please note that your feedback on any aspect of this course will be greatly appreciated. Anytime, you can talk to me to give your informal feedback. However, I will be taking two written feedbacks from you - one just after Minor-I and the other, a week before the Major. I expect you to be objective and enthusiastic to give your feedback.
