Abstract

Apparatuses including circuit layout regions of a semiconductor device and methods of designing the circuit layout regions of a semiconductor device are described. An example apparatus includes a first layout region including a first transistor area including at least one first transistor, at least one contact in proximity to the first transistor area, and a first resistor area comprising at least one first resistor coupled to the at least one first transistor. The first transistor area and the at least one contact are aligned in a first direction, and the first transistor area and the first resistor area are aligned in a second direction. The second direction may be substantially perpendicular to the first direction. The at least one contact may be one of a substrate contact and a well contact.
