About this course

Skip About this course

This course is part of the Principle of Semiconductor Devices Professional Certificate Program.

As a topic of study, semiconductor devices offer a unique challenge due to the complex mathematics involved. In this course, we take a more intuitive approach to exploring the underlying concepts. We shift the focus from quantitatively evaluating the behavior of semiconductor devices to intuitively visualizing the semiconductor device actions.

Following the approach from Course 1 in the program, we expand the understanding from PN junction diodes and BJTs to MOS capacitors, charge coupled devices and MOSFETs. In addition to describing the theory of MOSFETs, the course covers some more recent development in non-traditional nano-CMOS transistors. Besides covering the existing technologies, the course will also enable you to project the development of the industry in the near future.
