The poly2 layer is a second polysilicon layer (physically above the standard, or first, poly layer). The oxide between the two polys is the capacitor dielectric. The capacitor area is the area of coincident poly and electrode.
|11.3||Minimum poly overlap||2||5||n/a|
Minimum spacing to active or well edge
|11.5||Minimum spacing to poly contact||3||6||n/a|
|11.6||Minimum spacing to unrelated metal||2||2||n/a|
|12.3||Minimum electrode gate overlap of active||2||2||n/a|
|12.4||Minimum spacing to active||1||1||n/a|
|12.5||Minimum spacing or overlap of poly||2||2||n/a|
|12.6||Minimum spacing to poly or active contact||3||3||n/a|
The poly2 is contacted through the standard contact layer, similar to the first poly. The overlap numbers are larger, however.
Contacts must be drawn orthogonal to the grid of the layout. Non-Manhattan contacts are not allowed.
