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.
