DataPrep (Layout/ ProximityEffectCorrection/ Simulation)

• Layout creation / processing of customer layout

(formats: GDSII, OASIS, DXF, CIF)
• Check the success of correction of critical structures with simulation
• Place the pattern in the wafer map

• Fracturing and Proximity Effect Correction:

    • Without any correction the electron scattering and resist

    effects would lead to difference between layout and exposure result →

    proximity effect

    • Proximity effect can be corrected

    • Optional: Proximity parameters are extracted from test exposures

    (not necessary for known stacks and resist processes)

    • Customer pattern is corrected with proximity parameters
