| RULE NO.,DESCRIPTION,LAYOUT RULE |
| ANT.16,"If any of the above antenna ratio rules fails then the antenna diodes |
| |
| shall be connected in a reverse bias mode between the metal line |
| |
| failing antenna ratio (connected to gate poly or MIM cap top plate) |
| |
| and the substrate underneath. |
| |
| |
| For DRC check if Metaln or Vian fails antenna ratio then it shall |
| |
| check whether this Metaln or Vian is directly connected to COMP |
| |
| through lower level metals, vias and contacts or not? |
| |
| Case (a): Connection to COMP is not present: Flag error |
| |
| Case (b): Connection to COMP is present: Then: |
| |
| |
| (i) For Thin gate case: (COMP AND Poly2 NOT DUALGATE): |
| |
| Treat Gate area = (thin gate area + |
| |
| MF* (COMP area directly connection that node)) |
| |
| |
| This comp area contained the protection diode and any other |
| |
| drain or source junction connected to this node. |
| |
| MF: stand for multiplying factor, for this case MF=2 |
| |
| (ii) For Thick gate case (COMP AND Poly2 AND |
| |
| DUALGATE) Treat Gate area = (Thick gate area + |
| |
| MF* (COMP area directly connection that node)) |
| |
| |
| This comp area contained the protection diode and any other |
| |
| drain or source junction connected to this node. |
| |
| |
| MF: stand for multiplying factor, for this case MF=15 |
| |
| |
| (iii) For MIM Cap case: |
| |
| Treat MIM area = (FuseTop area + MF* (COMP area directly |
| |
| connection that node))(For MIM option-A process) |
| |
| |
| Treat MIM area = (FuseTop area + MF* (COMP area directly |
| |
| connection that node))(For MIM option-B process) |
| |
| This comp area contained the protection diode and any other |
| |
| drain or source junction connected to this node. |
| |
| MF: stand for multiplying factor, for this case MF=15 |
| |
| And check back the validity of antenna ratios as specified in |
| |
| rules ANT.1 to ANT.15.", |
