Abstract: A method of manufacturing an IC structure includes configuring each of an n-well and a p-well in a first IC die to have a first portion extending in a first direction and second and third portions extending from the first portion in a second direction perpendicular to the first direction, and forming IC devices including a first pickup structure electrically connected to the n-well and a second pickup structure electrically connected to the p-well. Forming the IC devices includes forming a PMOS transistor in the second or third portion of the n-well and forming an NMOS transistor in the second or third portion of the p-well.
