BEOL variability and impact on RC extraction
2005
Historically, back end of line (BEOL) or interconnect resistance and capacitance have been viewed as parasitic components. They have now become key parameters with significant impact on circuit performance and signal integrity. This paper examines the types of BEOL variations and their impact on RC extraction. The importance of modeling systematic effects in RC extraction is discussed. The need for minimizing the computational error in RC extraction before incorporating random process variations is emphasized.
