This course is focused on understanding CMOS nanotechnology at the current
state-of-the-art and beyond, and will provide the physical background
behind modern VLSI technology leading to an understanding of process
interactions and process integration. Process simulation using
commercial TCAD tools will be used extensively to illustrate and
explore the technology. A project will be required along
with a midterm, final and homeworks (which will also have simulation
problems).
Target Audience: Graduate students and advanced undergraduates
in EE, materials science, physics, chemical engineering, mechanical
engineering, chemistry, etc. interested in Nano/Microtechology and/or
VLSI CAD.
Course Description: Physics of VLSI fabrication technology,
with emphasis on process modeling and simulation. CMOS process
sequences, point defects and diffusion, ion implantation and
annealing, film growth kinetics, deposition and etching, advanced
photolithography techniques. Process interactions and process
integration. Extensive use of process simulation software for both
class examples and assignments. 4 class. 4 cr.
Text: Silicon VLSI Technology: Plummer, Deal and Griffin

TCAD Software info
Simulation Software (Sentaurus Process):
The simulation software is
available on weber.ee.washington.edu. To access the required license file,
you will need to run "/usr/local/cadenceusers/create_cadence" before trying TCAD software. The example files are in /usr/local/synopsys/Y_2006.06-SP1/tcad/Y-2006.06-SP1/lib/sprocess. The manuals are located at /usr/local/synopsys/Y_2006.06-SP1/tcad/Y-2006.06-SP1/manuals/PDFManual. Do not print the manuals out. They are HUGE. You can make a copy to read on your local machine. If you do, copy the entire directory tree, then you can access all the manuals from front.pdf. To begin, read Getting Started section of Sentaurus-Process Manual. To run, type "sprocess commandfile" (commandfile is the file with commands telling simulator what to do). You will likely have to either use the full path name: /usr/local/synopsys/Y_2006.06-SP1/bin/sprocess or add /usr/local/synopsys/Y_2006.06-SP1/bin to your path. If you are not familiar with Unix, you might want find an online Unix tutorial.
