Case Study: Ultrathin Free-Form Micro-Optical Element (FFMO)
Problem: Fabricating complex ultrathin FFMOs with traditional methods led to significant surface deviations, affecting optical performance and requiring costly, time-consuming iterations.
Solution: The AI-driven optimization algorithm was applied to generate a virtual photomask for an FFMO, leveraging its predictive capabilities to account for non-linear photoresist response and proximity effects.
Outcome: The optimization algorithm reduced the average Euclidean distance error between experimental and target surfaces from 3.6 µm to 1.0-1.2 µm in a single build. This improvement ensures accurate peak heights, valley depths, and aligned sloped surfaces, enhancing optical functions like anti-reflection and focusing efficiency, and enabling "first time right" manufacturing.
Learn how a data-driven approach facilitates rapid adaptation to new materials and equipment, streamlining calibration and accelerating time-to-market for innovative micro-optical solutions.
Key Finding: Training Time for ANN
Despite the large dataset, the optimized ANN training is highly efficient, allowing for rapid model updates and deployment.
3 Minutes (M2 Processor)This rapid training time underscores the efficiency of the selected ANN architecture and hardware, enabling quick calibration and adaptation for new photoresists or MGLL setups without extensive delays.
Key Finding: Optimization Convergence Speed
The iterative optimization of virtual photomasks converges quickly to a stable solution, significantly reducing the design cycle.
30 Iterations (for <10nm error)This fast convergence, achieved in less than two minutes for complex elements, means that optimized virtual photomasks can be generated rapidly, facilitating agile development and production of micro-optical elements.
