There are many NPTEL courses that people refer to build their concepts in VLSI and Semiconductors. Thanks to Nikhila who shared the list of NPTEL courses.
NPTEL recently launched “domain certification”. This is basically a list of recommended core and elective courses for a particular domain. For VLSI and Semiconductors learner, a specialization called “VLSI design” is created under the Electrical Engineering discipline.
