FDSOI is a really interesting technology for low power but doesn't have enough support amoung device manufacturers to be anything more than a niche. I ran through the math in an article posted here: https://www.semiwiki.com/forum/content/3128-soi-future-flop.html I don't see it representing more than 5% of leading edge logic.
450mm is likely pushed out until after 2020 to around 2023.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
