5. Doping (Ion Implantation or Diffusion).zip
Doping is the process of introducing impurity atoms (such as boron, phosphorus, or arsenic) into the silicon wafer to modify its electrical properties, enabling the formation of p-type or n-type regions. This step is essential for defining transistors, diodes, and other active devices.

Good Doping Images
A successful doping process results in accurate dopant concentration, uniform depth, and well-aligned profiles in the intended regions of the wafer.
-
Sharp junction boundaries
-
No crystal damage
Not Good Doping Images
Poor doping can lead to electrical malfunction, leakage current, or degraded device performance.
-
Crystal damage
-
Excessive lateral diffusion — spreading beyond intended areas
