Deep nwell contact structures

Integrated structures include (among other components) a deep well structure having a first impurity, well rows contacting the deep well structure and having a second impurity, a well contact ring enclosing the well rows within an enclosed area, a transistor layer on the well rows, transistors within the transistor layer, and at least one ring-enclosed contact contacting the deep well structure. The ring-enclosed contact is positioned within the enclosed area. Such structures further include a well contact connection contacting the well contact ring and the ring-enclosed contact.
