A 3D integrated circuit device, including: a first transistor; a second transistor; and a third transistor, where the third transistor is overlaying the second transistor and is controlled by a third control line, where the second transistor is overlaying the first transistor and is controlled by a second control line, where the first transistor is part of a control circuit controlling the second control line and third control line, and where the first transistor, the second transistor and the third transistor are all aligned to each other with less than 100 nm misalignment.
