Learning unit contents
In this course, we introduce the fundamental physical concepts underlying semiconducting devices. We expose the physics of semiconducting materials and introduce the main transport models (drift-diffusion). These notions are then applied on an analysis of the electrical behavior and performance of various electronic components.
More precisely, the following elements are discussed:
crystal structure of semiconductors, energy bands, n- and p-dopings, Fermi distribution and Fermi sea, drift in an electrical field, in a magnetic field, diffusion, optical absorption, luminescence, excess carrier lifetime.
The concepts are illustrated on pn junctions (static equilibrium, direct and inverse biases), metal-semiconductor junctions, bipolar and field effect transistors, MOS capacitors.
Learning outcomes of the learning unit
To be able to:
- explain the physics of semiconducting junctions and transistors
- understand and state the equations describing the basic phenomena underlying the drift-diffusion model,
- know the orders of magnitude involved in thermal or optical generation of carriers, in their transport, their collection or their recombination,
- assess the influence of the fundamental parameters involved in semiconductors on the electrical performance of devices.
This course contributes to the learning outcomes I.1, I.2, II.1, II.2, III.1, III.2, VI.1 of the MSc in biomedical engineering.

Prerequisite knowledge and skills
It is recommended to have followed a course on analog electronics or to have read the first three chapters of the course "ELEN0075-1 - Analog electronics" in order to better grasp the general context of this course.
Planned learning activities and teaching methods
The course is composed of "ex-cathedra" sessions (30 hours) and practical sessions (30 hours).
The "ex-cathedra" sessions are devoted to the description of the fundamental concepts of semiconductor physics, charge carrier generation, transport equations, and an illustration of these notions in semiconductor devices.
The practical sessions are devoted to an applicaton of the concepts on specific examples. Typically, an exercice illustrates a given mechanism, a genuine model, and relevant orders of magnitude. Students are invited to participate actively to these sessions.

- In-person
written exam ( open-ended questions )
Further information:
A written exam is organized during the January exam session. It starts with a theory part (1h30), which covers the theory concepts seen in the "ex cathedra" part and in the exercice sessions. It is followed by an exercice part (2h30), on problems similar to those seen in the exercice sessions.
The entire exam is 'closed book'. For the exercice part only, forms are distributed and calculators are required. Cell phones and smartphones are forbidden for the entire exam.
The theory and exercice parts account for respectively 1/3 and 2/3 of the final grade.
The same rules apply for student having to take the exam in September.
Erasmus and exchange students's exams are subjected to the same modalities.
