This paper compares the range of accepted layouts produced by conventional Shape Driven Proximity Correction (SDOPC) and Electrically Driven Optical Proximity Correction (EDOPC). For SDOPC, correction is made until a target geometry matches a layout. In EDOPC, current matching is the primary objective.1-6 Using electrical objectives results in a smaller fragmentation requirement for an equivalent current accuracy as SDOPC. Number of candidate OPC solutions accepted by EDOPC is orders of magnitude higher than SDOPC leading to potentially much faster convergence. Moreover, due to additional flexibility in EDOPC, it is able to correct several layouts which are not correctable by SDOPC with the same fragmentation.
