The stick diagram is the symbolic representation of the layout of the transistor. Each layer is represented by a different color as shown below:
| Layer | Color | Representation |
| n diffusion | Green | |
| p diffusion | Yellow | |
| Polysilicon | Red | |
| Metal 1 | Blue | |
| Metal 1 | Magenta | |
| Contact | Black | |
| Buried Contact | Brown | |
| Implant | Dotted yellow | |
| N-well | Dotted Green/Black |
Analysis: Using the above table, we get
(A) Contact - Black or Brown
(B) Polysilicon - Red
(C) Metal - Blue/ Magenta
(D) Implant - Yellow
Hence, only statements (A), (C), and (D) are correct.
