Goal(s)
The goal of this course is to give a general view on the fabrication processes that exist in microelectronics. Focus is made on integrated silicon applications. Various standard technologies will be presented in CMOS bulk, BiCMOS, FD SOI, interposers. Special attention will be paid on RF and millimeter waves constraints. Weighing between the pros and cons will enable to enface a specific technology for a specific application, digital and/or analog, RF and/or millimeter waves. An overview of potentially future trends will be drawn also with alternative technologies: MEMS vs varactors for tunability, graphene for very high mobility channels. An 8-hour tutorial in the very nice cleanroom of the CIME-Nanotech will illustrate this class.
