Objectives: This is only the second time this class has been offered here at UT-Austin. At this moment I am still adding to the class notes from last year. The overall objective of this class is simple: what good are "micro-machines"? We will begin with an overview of some of the processing techniques commonly used for MEMS fabrication. These techniques are usually adapted from IC processing: we will discuss basic materials, some mechanical properties, then concentrate on deposition, lithography, and etch (wet and dry). We will then discuss applications of MEMS technology to actuation and sensing. I will try to use some "case studies" to investigate the utility of MEMS devices. We will most likely look at temperature, pressure, acceleration, RF, optical, and chemical applications.
Class Projects: You must complete a class project, which will count for 40% of your grade. The project will consist of the identification of a MEMS device/system that is actually used in a commercial product, and a detailed, critical examination of the product development history to identify why/if a MEMS devices actually improved the performance of this system. You will then prepare a written term paper on your findings (thoroughly referenced!!), as well as giving a DETAILED oral presentation (about 20 minutes) to the class. Before making your class presentation expect to spend at least two hours with me, with a return visit to clarify any problems (and I guarantee I will find something to object to) identified in your first meeting with me. Class presentations will begin in early to mid-April.

Your grades will be based upon performance on homework, exams, and the class project. Homework will be assigned approximately weekly; credit for late homework will be reduced at a rate of 10% per class the work is late.
The weighting for different areas is:
Class project 40%
The worst-case grades will be based on:

Policy on CHEATING:
You are expected to do your own work at ALL times. I expect you will often discuss assignments, but you MUST do your own ORIGINAL written work. Any evidence of cheating or plagiarism* will be treated as grounds for FAILURE in the class.

*"A CASE OF PLAGIARISM
"May is a second-year graduate student preparing the written portion of her qualifying exam. She incorporates whole sentences and paragraphs verbatim from several published papers. She does not use quotation marks, but the sources are suggested by statements like '(see . . . for more details).' The faculty on the qualifying exam committee note inconsistencies in the writing styles of different paragraphs of the text and check the sources, uncovering May's plagiarism.
"After discussion with the faculty, May's plagiarism is brought to the attention of the dean of the graduate school, whose responsibility it is to review such incidents. The graduate school regulations state that 'plagiarism, that is, the failure in a dissertation, essay, or other written exercise to acknowledge ideas, research or language taken from others' is specifically prohibited. The dean expels May from the program with the stipulation that she can reapply for the next academic year." [ URL: http://www.nap.edu/readingroom/books/obas/contents/misconduct.html#Plagiarism]
"A broad spectrum of misconduct falls into the category of plagiarism, ranging from obvious theft to uncredited paraphrasing that some might not consider dishonest at all. In a lifetime of reading, theorizing, and experimenting, a person's work will inevitably incorporate and overlap with that of others. However, occasional overlap is one thing; systematic use of the techniques, data, words, or ideas of others without appropriate acknowledgment is another."
