Smarter Masks for Better Chips: A New Dataset Drives AI-Powered IC Manufacturing

Researchers have unveiled a large-scale dataset designed to accelerate the development of AI algorithms that optimize the complex process of creating masks used in integrated circuit fabrication.

![Parallel token prediction streamlines sequence generation by enabling a single model call to predict multiple tokens simultaneously, achieved through either integrating sampling directly into the model-using auxiliary variables-or by modeling and predicting the distribution of each token in parallel with those same variables, a departure from traditional autoregressive models that predict tokens one at a time [latex] t_{i} [/latex].](https://arxiv.org/html/2512.21323v1/x2.png)



![A grid-based autoregressive sampling algorithm efficiently generates arbitrary-length, high-quality image sequences by iteratively refining a coarse grid: initial sampling via a Stage 1 diffusion model is followed by iterative refinement using noised control signals to produce spatiotemporally consistent grid elements, then interpolation generates eight new frames between each pair, and finally, a Stage 2 super-resolution step enhances both spatial and temporal fidelity, achieving a sequence length of [latex]L = \frac{12N - 4}{N}[/latex] and surpassing state-of-the-art performance.](https://arxiv.org/html/2512.21276v1/images/snowflake.png)
