forming the first active portion includes forming the first active portion next to a side of the insulation region, the first active portion having a spacing from the contact; and

further comprising:

forming a second active portion next to another side of the insulation region, the second active portion having a spacing from the contact.

8. The method as claimed in claim 6 wherein:

forming the first active portion includes forming the first active portion adjacent the contact, the first active portion having a vertical side substantially parallel to a vertical side of the contact; and

further comprising:

forming a second active portion adjacent the contact, the second active portion having a vertical side substantially parallel to another vertical side of the contact.

9. The method as claimed in claim 6 wherein forming the first active portion includes forming the first active portion adjacent the contact, the first active portion having a plane of a top side substantially aligned to a plane of a bottom side of the contact.

10. The method as claimed in claim 6 further comprising forming an active portion adjacent the insulation region formed as a shallow trench isolation, the active portion having a side adjacent the sealring and another side adjacent another of the sealring.

11. An integrated circuit system comprising:

an insulation region in a base layer;

an insulator in the insulation region wherein the insulator is over an active portion and around a perimeter of a main chip region including an integrated circuit;

a contact directly on and within planar extents of the insulator in the insulation region; and

at least one sealring having an upper layer over the contact with the sealring surrounding and isolating an active surface area in the main chip region.

12. The system as claimed in claim 11 further comprising:

a first active portion next to a side of the insulation region; and

a second active portion next to another side of the insulation region.

13. The system as claimed in claim 11 further comprising:

a first active portion adjacent a vertical side of the contact; and

a second active portion adjacent another vertical side of the contact.

14. The system as claimed in claim 11 further comprising a first active portion adjacent the insulation region, the first active portion having a plane of a top side substantially aligned to a plane of a bottom side of the contact.

15. The system as claimed in claim 11 further comprising:

an active portion adjacent the insulation region; and wherein at least one of the sealring includes:

the sealring adjacent a side of the active portion; and

another of the sealring adjacent another side of the active portion.

16. The system as claimed in claim 11 further comprising:

a first active portion in the base layer, the insulation region adjacent the first active portion and entirely around the perimeter of the main chip region;

a layer one directly on the contact;
