ELEC6710 Semiconductor Devices Spring 2010 (Guofu Niu)
Part of our notes are in blackboard, I will try to use less blackboard for this class, as I have more space to use here, particularly with the large size high quality videos.
Class Notes:
1. 1/19/2010 notes on basics of semiconductors, really a mini review for 6700, certainly not meant to replace 6700, need windows journal viewer!
2. Zipped r6710 examples - Please use this file with readme.docx before next class, practice, discuss with each other, particular 6700 veterans around your office.
3. 1/21/2010 updated notes on basics of semiconductors, homework no. 2 is around page 100.
4. 1/22/2010 I have created a video tutorial of Sentaurus work bench, you need a media player that can play windows media video (WMV). It takes a lot of effort to make such a video, so please go through all of it, and let me know of any problems. The very last part is not quite right, it was a plt file, not a dat file, so it is voltage dependent, not position dependent. You can expand on this, for instance, create a parameter called type, it can be “n” or “p”, then you can produce electron / hole mobility as a function of majority / minority carrier doping all in the same project. You should be able to use this as a template. The inspect script is the most difficult, as there is little information in the manual or the examples. Part of the script can be generated by recording the interactive mouse clicks. However, generating the data set and file names, as well as generating / returning variables to the workbench can only be done with manual scripting.
5. The input files you need to follow the video tutorial of Sentaurus work bench are here.
6. 1/28/2010 updated notes on basics of semiconductors
7. PN Junction class notes 2/2/2010.
8. My undergraduate class 2210 PN Junction equilibrium notes.
9. PN junction first homework assignment – I have given you my mesh.cmd file in this homework. Due Thursday’s class time. Needs to be emailed to me 20 minutes before class. Be prepared to speak on your results on Thursday.
10. PN Junction homework sample plots – what to look for. I have not used tecplot much, so I am learning too. Here are some sample plots I made last night. I recommend you using ps plots, and then use ps2pdf to convert it to PDF. Or you can use EPS, and include it in Word or Latex. Choose your word processing options so that you get the vector version, not the bitmap version PDF output. Note default page size in tecplot is A4, change it to letter size to avoid problems of plots going out of page limits in the PDF. You can also do conversion online at ps2pdf.com.
11. Updated PN junction notes.
12. Charge storage in PN Junction (updated Feb 11 – same file name).
13. Breakdown behavior of PN junctions and high voltage applications (almost done, avalanche to be treated, Feb 11, Feb 18).
14. Frequency domain small signal ac electrical characteristics of PN junction, solution of transport equations in frequency domain (Feb 11)
16. Homework on advanced PN junction transient characteristics, Sentaurus Device Simulation results (2/16)
17. Bipolar transistor fundamentals (2/18, updated 3/4)
18. Streamtraces of electron and hole current flows in SiGe HBTs (2/25)
19. Homework on VCE effect (you could change biasing configuration to common base to examine VCB effect) (3/4)
20. Vertical field effect in CMOS: Polysilicon/oxide/silicon capacitor electrostatics, surface modulation, surface potential and inversion charge modulation (3/11)
21. MOS charge (3/23)
22. Inversion charge in MOS systems (3/25)
23. Matlab programs for understanding vertical field-effect in MOS (3/23, 3/25)
24. MOS and MOSFET capacitors – LF/HF CV, split CV, Sentaurus simulation (see homework assignment on page 13 – due next Tue) (3/30) (added RF MOS capacitor, Varactor).
