Abstract: An integrated circuit includes laterally adjacent first and second devices. The first device includes a first source or drain region, a first gate structure, and a first inner spacer between the first source or drain region and the first gate structure. The second device includes a second source or drain region, a second gate structure, and a second inner spacer between the second source or drain region and the second gate structure. In an example, the first source or drain region has a width that is at least 1 nanometer different from a width of the second source or drain region, and/or the first inner spacer has a width that is at least 1 nanometer different from a width of the second inner spacer. The various widths are measured in a direction of a semiconductor body between the first source or drain region and the first gate structure
