QA cells: misunderstanding in Gat.b1 rule

[mole99]

The GatPoly Gat.b1 rule is defined as follows:

Rule	Description	Value
Gat.b1	Min. space between unrelated 3.3 V GatPoly over Activ regions	0.25

The corresponding image is as follows:

To me, this would indicate that the spacing or notch of related HV GatPoly on the same Activ region is still defined by the Gat.b rule as 0.18um. Only for the HV GatPoly of unrelated regions of Activ the spacing is 0.25.

And yet the layout in the QA cells for Gat.b1 tests for the spacing/notch of HV GatPoly on a related region of Activ to be >= 0.25um.

Pass	Fail

Hi @mole99, forwarded to the internal team, but the reply for sure will be delayed after Christmas :-)

Thank you, @sergeiandreyev! Yes, I didn't expect it any differently ;)
