Real-world impact of inverse lithography technology
In this paper we describe, from the user's point of view, how Inverse Lithography Technology (ILT) differs from Optical Proximity Correction (OPC). We show simulation and experimental results from 90nm and 65nm semiconductor nodes, comparing ILT-generated masks and OPC-generated masks for real-life layouts, in a production environment.

A Gradient-Based Inverse Lithography Technology for Double-Dipole Lithography
Resolution enhancement techniques (RETs) have become indispensable for the sub-wavelength optical lithography. Inverse lithography technology (ILT) is one kind of RETs, which attempts to consider the mask synthesis as an inverse problem and compute the optimum mask by using the entire area of the design pattern with a rigorous mathematical approach ...

SRAF placement and sizing using inverse lithography technology
The use of sub-resolution assist features (SRAFs) is a necessary and effective technique to mitigate the proximity effects resulting from low-k1 imaging with aggressive illumination schemes. This paper investigates the application of one implementation of Inverse Lithography Technology (ILT) to determine optimized SRAF placement and size.

Advanced memory cell design optimization with inverse lithography technology
Memory cells and access structures consume a large percentage of area in embedded devices so there is a high return from shrinking the cell area as much as possible. This aggressive scaling leads to very difficult resolution, 2D CD control and process window requirements.

Inverse lithography technology principles in practice: unintuitive patterns
In this paper we present unintuitive patterns generated by inverse lithography technology. We show examples of contact hole masks designed with ILT that enjoy larger process windows than OPC. We also show variations in ILT-generated masks as the pitch of the contact hole array changes.

Fast inverse lithography technology
Many RET technologies, such as rule and model based OPC, the use of sub-resolution assist features, and various PSM methodologies, can be thought of as heuristics employed in an attempt to design improved photomasks. Unfortunately, these traditional approaches are running into severe difficulties at advanced technology nodes (90nm and beyond).

Inverse lithography technology at chip scale
In this paper we describe, from the user's point of view, how Inverse Lithography Technology (ILT) differs from Optical Proximity Correction (OPC). We discuss some specifics of ILT at chip-scale. We show simulation and experimental results from 90nm and 65nm semiconductor nodes, comparing results from ILT-generated masks and OPC-generated masks for ...
