N well

Semiconductor n-well region shown either in cross section or simple layout style as a broad rectangular to rounded-rectangular implanted pocket embedded within a differently shaded p-type silicon substrate. The well is lightly tinted blue, cyan, green, or purple to indicate n-type doping, with smooth clean boundaries, often rounded lower corners or curved sidewalls and a flat upper boundary near the wafer surface. It appears as a distinct embedded basin or pocket used to host PMOS device areas, and may be labeled n-well or include repeated donor markers indicating n-type material.
