Abstract (en)

[origin: WO2018117275A1] Method of manufacturing electronic devices using a maskless lithographic exposure system using a maskless pattern writer. The method comprises generating beamlet control data for controlling the maskless pattern writer to expose a wafer for creation of the electronic devices, wherein the beamlet control data is generated based on a feature data set defining features selectable for individualizing the electronic devices, wherein exposure of the wafer according to the beamlet control data results in exposing a pattern having a different selection of the features from the feature data set for different subsets of the electronic devices.
