DIFCAD calculates diffusion profiles for typical dopants in silicon.

Be sure that you are using the latest version (2.1), or your results will be erroneous!

Here is a typical screen image.

DIFCAD2 was updated (to version 2.1) in January 1997. Version 2.1 corrects an error in the previous version for predep profiles, and also keeps the background concentration species from run to run during each session.

The DIFCAD add-in is available on the ccso computers (Macs and PCs) in the class software directory, in the ece344 directory.

You may also download the software: To download the needed files, you MIGHT have to select "download to disk" or hold the SHIFT key while selecting the particular file ,or hold down the mouse button on the filename and select "Save this link as..." AFTER you click on one of the links below.

  1. DIFCAD 2 - An EXCEL 5 spreadsheet add-in by Anthony Hill. (Use "Tools"-"Add-Ins"-"Browse" to load it into EXCEL 5.) Good on-line help. The readme.txt file contains information about installing the add-in.
  2. DIFCAD 2 source - same as above, but bigger because it includes the source so interested people can find out HOW it works.
  3. Older DIFCADs
