Abstract
An integrated circuit comprises standard cells arranged in rows and columns. The integrated circuit also comprises tap cells arranged in rows and columns. The tap cells each comprise a substrate having a first dopant type and a thickness from a first surface of the substrate to a second surface of the substrate. The integrated circuit further comprises a well region in the substrate having a second dopant type different from the first dopant type and a depth from the first surface of the substrate less than the thickness of the substrate. The integrated circuit additionally comprises a first quantity of rows of tap cells and a second quantity of rows of tap cells less than the first quantity. Each row of the first quantity of rows of tap cells comprises at least one well contact, and each row of tap cells of the second quantity of tap cells comprises at least one substrate contact.
