Patent ID: 10192861

Abstract:
The present invention discloses an OPC method for a shallow ion implanting layer, comprising the following steps of: selecting a valid device region in an implanting active region in a shallow ion implanting original layout; selecting a region in the valid device region which is contacted with a poly-silicon pattern in a poly-silicon layer, as a poly-silicon contacting region; extending the length and width of the poly-silicon contacting region and the non poly-silicon contacting region, to form a new poly-silicon contacting region and a new non poly-silicon contacting region; combining a gap portion which an interval between any two new poly-silicon contacting regions and/or new non poly-silicon contacting regions after extending is smaller than or equal to G and completely fallen in the STI region, with the poly-silicon contacting regions and non poly-silicon contacting regions after extending, to form a correction target layer; performing a model-based OPC routine on the correction target layer, to obtain a mask layer.
