Claim 13:
14. A method of forming an integrated circuit structure, comprising:
forming a tap cell comprising:
providing a substrate having a first region and a second region extending along an X direction;
forming a first well having a first dopant type in the substrate, wherein the first well comprises a first portion in the first region; and a second portion adjacent to the first portion and extending into the second region to form a first jog;
forming a second well having a second dopant type different from the first dopant type in the substrate, wherein the second well comprises a third portion in the second region; and a fourth portion adjacent to the third portion and extending into the first region to form a second jog;
forming a first doped region having the first dopant type in the second portion of the first well and the third portion of the second well along the second region; and
forming a second doped region having the second dopant type in the first portion of the first well and the fourth portion of the second well along the first region.
