Prerequisites: Graduate standing or consent of instructor.

Course Description: Fabrication and characterization of micro-scale devices, including micro-electrical-mechanical systems, sensors, optical devices, and micro-fluidic devices.

Goals and objectives: Learn the techniques of fabricating and characterization micro-scale devices in a hands-on clean-room environment. Topics include photo- and electron-beam lithography, electron-beam evaporation, sputtering, metal lift-off, reactive ion etching, inductively coupled plasma etching, barrel ashing, wet etching, plasma-enhanced chemical vapor deposition, sacrificial layers, optical microscopy, profilometry, microprobe-station, 4-point probe resistivity measurement, scanning electron microscopy, UV-visible spectroscopy, atomic force microscopy. A goal is that students who pass this course can be given key-card access to the facilities to begin their dissertation research.

Required text: S. Wolf and R. N. Tauber, Silicon Processing for the VLSI Era, Volume 1-Process Technology, (Lattice Press, Sunset Beach, CA 1986).

Course calendar:
First month: Environmental Health and Safety training, Photolithograpy, descum, metal deposition, and lift-off. Optical microscopy.

Second month: PECVD oxide growth, wet etching. Profilometry. 4 point resisitivity measurement.

Third month: RIE-ICP etching, barrel-ashing, scanning electron microscosopy, Electron-beam lithography, UV-vis spectroscopy, atomic force microscopy.

Fourth month: Make and characterize final project device: Deep fluid channels, optical planer waveguides, air-bridges, cantilevers,

Course assignments (assignments and exams): This is a hands on laboratory with all class time spent in the physics Microdevice Prototyping Facility (MPF). There will be assigned reading, one midterm and a final based on the assigned reading and standard operation procedures for the instruments in MPF, and a final fabrication project.

Methods of evaluation: Participation will count for 25%, midterm 25%, final project 25%, final exam 25%. The final course grade will be available on myucf.

PHYSICS DEPT MISSED WORK POLICY: Making up missed work is permitted only for UCF-sanctioned activities and bona fide medical or family reasons. Authentic justifying documentation must be provided in every case (in advance for UCF-sanctioned activities). The form of the make-up will be determined by the instructor.
