大綱：

Traditionally, after ID circuit design and layout, it takes months to fabricate an IC wafer, involving a multiple-step sequence of photolithographic and chemical etch processing, which can significantly deform the layout patterns and is too complex to model mathematically. Usually we cannot identify defects (e.g., broken wires) of metal wires due to deformations of IC circuit shape caused by a fabrication process until capturing the scanning electron microscope (SEM) images of fabricated IC wafers, making the circuit design and verification very costly and time-consuming. To address the above problem, there are three essential concerns in terms of IC design for manufacturability (DfM): (1) How to predict the manufactured IC circuit shape from an IC layout so as to assess the layout quality accordingly in a pre-simulation process; (2) How to automatically modify photomask patterns so that the manufactured IC circuit shape can match the desired patterns as close as possible; (3) How to efficiently update the learned prediction models by detecting and learning from novel layout patterns. In this talk, we will show how deep-learning-based computer vision can effectively and efficiently address the above three issues and help improve IC DfM.
