(4) Double patterning
The double patterning is divided into four parts, leading with wafer requirements and then two sets of lithographic requirements (Generic Pitch Splitting - Double Patterning Requirements Driven by MPU metal Half-Pitch and Generic Spacer Patterning Requirements - Driven by Flash).
