Because these semiconductors are approaching fundamental limits of physics, it is unlikely that TSMC can achieve this status with anything like the current technology. I think that Sophie Wilson said that cost-per-part is rising since we surpassed 22nm, heat is more of a problem because finfet can't dissipate as well as planar, and reliability is declining at smaller nodes. If I needed a 20-year service life, I would not choose 7nm. Sophie addresses the cost rise at 22:00. https://m.youtube.com/watch?v=zX4ZNfvw1cw https://m.youtube.com/watch?v=zX4ZNfvw1cw
