Joint Effort Targets Improved OPC Modeling Accuracy, Reduced Time to Model and Enhanced Model Predictability
At 45 nanometers and below, the process window becomes extremely small and a very tight error budget is required for accurate critical-dimension (CD) control. OPC models must accurately capture a wider scope of effects and process variations. This requires a large sampling of physical measurements, including a wide range of critical 2D structures. Synopsys and NGR are working with a joint customer, a large semiconductor manufacturer, to develop a common interface that works with both Synopsys' Proteus OPC tool and NGR's NGR2100 wafer inspection system.
"We believe the accuracy, stability, and time-to-modeling for OPC can be significantly improved by incorporating our wafer pattern data into Proteus modeling," stated Masahiro Yamamoto, CEO, NanoGeometry Research Inc. "By collaborating with Synopsys, the leader in DFM solutions, we can provide better predictive lithography models for our customers, helping them reduce the time required to develop a lithography process."
The interface that Synopsys and NGR are developing will allow Proteus modeling to automatically link to metrology data obtained from NGR's wafer inspection tool NGR2100. With this new integration, Synopsys and NGR's mutual customers can quickly obtain a wide range of scanning electron microscope (SEM) measurements, and accurately overlay over the input layout data. Proteus customers can achieve higher model accuracy, more predictive 2D models and process window models.
"Together, Synopsys and NGR are addressing the escalating need for accurate, high-speed OPC modeling at the 45 nanometer node," said Anantha Sethuraman, Synopsys' vice president of marketing, Design for Manufacturing. "By addressing the complex technology issues our customers face at 45 nanometers and beyond, this collaboration will help them achieve their model production and yield goals, thereby reducing their overall cost of ownership."
The NGR2100 is uniquely designed to supply customers with millions of data points and feature contours, with a 10X reduction in data acquisition times versus traditional SEM metrology tools. NGR utilizes a large field of view (FOV) SEM image, stitch and butt image assembly and high speed data processing technology to verify every feature shape in the FOV versus its design intent for local regions, hot spots or whole die. With the number of transistor per die increasing exponentially, statistical significance and data confidence is lost using traditional sampling strategies. With its fourth shipment NGR has already shown a strong record for improving customer performance and product yields.
NanoGeometry Research is a privately funded, Tokyo-based company. Working closely with strategic suppliers and partners, NGR is committed to a path of innovative solutions for mass data collection for geometry verification at the 65 nm node and beyond. NGR's customers include some of the industry's most innovative leading-edge companies that must push the envelope to maintain market leadership. NGR's technology roadmap parallels these demands for statistically significant data collection, and features contour extraction in support of rapidly changing modeling and EDA solutions required by each progressive node and ever-changing lithographic strategies.
