Talking about the minimal fab with Leo Moser. Leo recently won a competition run by minimal fab and had a design fabricated.He's published a few blog posts about it here:About the Minimal Fab: https://mole99.uber.space/2023/Minimal_Fab/About%20Minimal%20Fab%20and%20the%20ICPS%20PDK.html NAND tutorial: https://mole99.uber.space/2024/NAND_tutorial/Design%20of%20a%20NAND%20gate%20using%20the%20ICPS%20PDK.html
