Will GPU-Acceleration Mean The End Of Empirical Mask Models?

Shrinking mask feature sizes and increasing proximity effects are driving the adoption of simulation-based mask processing. Empirical models have been most widely used to date, because they are faster to simulate. Today, GPU-acceleration is enabling fast simulation using physical models. Does the ability of GPU-acceleration to make physical models a practical solution mean the end of empirical ... » read more

GPU-Based Computing In Photomask Manufacturing

Graphical-processing unit (GPU)-accelerated computing has reached maturity for professional, scientific computing applications. One example of this is the recent GPU-accelerated thermal application for semiconductor photomask manufacturing, which is used in 24/7 manufacturing environments. GPU-accelerated computing won’t be a universal panacea for the semiconductor industry’s “need for sp... » read more

We Have Reached The Tipping Point For Simulation-Based Mask Data Preparation

Since the beginning of the semiconductor industry, mask-data preparation (MDP) and mask verification (MV) have been shape-based: each shape has been treated as an entity unto itself, and if each isolated shape was correct, the mask was correct. This context independence is a critical assumption for conventional fracturing. However, as line/space measurements (L:S) fall below 50nm, shape-ba... » read more

From The Whiteboard: David Lam

Multibeam's David Lam looks at changes in semiconductor lithography, how CVD and etch improve pitch resolution that is not attainable using optical lithography, and how e-beam direct-write can finish the job. [youtube vid=2ZCF-o7DXlU] » read more

Stopping Mask Hotspots Before They Escape The Mask Shop

By Aki Fujimura The same types of physics-based issues that have haunted lithography for decades have started to impact mask writing as well. The increasingly small and complex mask shapes specified by optical proximity correction (OPC) that are now required for faithful wafer lithography at 28nm-and-below nodes have given rise to an increase in mask hotspots. Mask hotspots occur when the shap... » read more
