Asymmetric source/drain regions of transistors

Abstract:

An example apparatus includes a first transistor and a second transistor, each having asymmetric source/drain regions. A source/drain region of the first transistor is directly coupled to a source/drain region of the second transistor at a junction. A depth of the junction is greater than a depth of another source/drain region of the first transistor and a depth of another source/drain region of the second transistor.
