Deep learning model predicts full-chip CMP nanotopography with nanometer accuracy

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a novel deep learning model to predict the full-chip post-Chemical-Mechanical Polishing (CMP) nanotopography with nanometer-scale accuracy. This model combines data from White Light Interferometry (WLI) and Atomic Force Microscopy (AFM) to overcome the limitations of existing Density Step Height (DSH) modeling, which is often slow and resource-intensive. The proposed Convolutional Neural Network (CNN) approach aims to accelerate the layout manufacturability verification process in the Integrated Circuit (IC) industry. AI

IMPACT This model could accelerate IC design cycles by improving the accuracy and speed of manufacturability verification.
