Carbon melts at approx 3600 C and vaporizes (boils) at 4200 C. They state "..vaporize them -- like a fuse -- thus cleansing the circuitry of all but the remaining semiconducting nanotubes..." It is to be hoped that this operation is carried out in an oxygen rich atmosphere as this will allow lower temperatures with the by- products carbon monoxide or dioxide and avoid, as might be the case with fusing, a field of carbon debris spreading over the rest of the wafer. Is this step carried out a wafer probe test time?
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.
