Abstract
An integrated circuit includes a vertical Shockley diode and a first vertical transistor. The diode is formed by, from top to bottom of a semiconductor substrate, a first region of a first conductivity type, a substrate of a second conductivity type, and a second region of the first conductivity type having a third region of the second conductivity type formed therein. The vertical transistor is formed by, also from top to bottom, a portion of the second region and a fourth region of the second conductivity type. The third and fourth regions are electrically connected to each other.
