Color Code for Stick
Diagrams and Magic Layout Editor
The following color code is rather standard for most CMOS processes and layout editors. We have access to only three layers of metal in the MOSIS AMI 0.5 micron CMOS process.
Also refer to the color palette in Magic by typing “:load palette” in a test window in magic.
You may need to type the full path name, such as
“:load /usr/site/cad/lib/magic/scmos/palette” You do not need to type the .mag file extension.
PolySilicon -- Red
Ndiffusion -- Green
Pdiffusion -- Brown
Metal1 -- Blue
Metal2 -- Purple
Metal3 -- Magenta
Contacts/Via -- Black “X” or “waffle” pattern
Nsubstrate Contact -- Green “X”
Psubstrate Contact -- Brown “X”
Note that some books use Yellow instead of Brown for Pdiffusion.
