For the fabrication of chips in this class, On Semiconductor 500 nm, the C5 CMOS process with two polysilicon layers and 3 levels of metal.

The MOSIS scalable CMOS (SCMOS) are found in submicron design rules.

A MOSIS technology code of SCN3ME_SUBM with a lambda of 300 nm is used with the design rules.

MOSIS information for this process is located here and the SPICE models are C5_models.txt    

The Cadence examples from the lectures are found in (upload to, and unzip in, $HOME/CMOSedu)  

Don't forget to add, to your cds.lib, DEFINE C5_f17 $HOME/CMOSedu/C5_f17 so the Library Manager sees the design directory

  • No laptops, Internet appliances (e.g. Kindle, Nook, Ipad, etc.), smart phones, may be used during lectures or exams.
  • If an exam or quiz is open book then only the course textbook may be used (no ebooks, Kindle, Nook, etc., older/international editions, or photocopies).
  • No late work accepted. All assigned work is due at the beginning of class.
  • The final exam will not be returned at the end of the semester, not even temporarily for you to review.
  • Regularly being tardy for lectures, leaving in the middle of lectures, or earlier from lectures is unacceptable without prior consent of the instructor.
  • Cheating or plagiarism will result in an automatic F grade in the course (so do your own homework and projects!)
  • Questions for the instructor (only) should be asked in person (not via email).
