Main themes
This training on advanced semiconductor devices follows naturally that of LELEC1330. It is focused on high performance devices in terms of speed, noise and temperature. The course highlights the links between physical phenomena, materials, fabrication and performances. Simulation and characterisation tools will be introduced. Content : Special semiconductors (heterostructures, SOI, III-V), HEMT, JFET, MESFET, Diodes, bipolar transistors, and small scale and high frequency MOS devices.

At the end of this learning unit, the student is able to :

1 In consideration of the reference table AA of the program "master in electrical engineering ", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:
  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.2, AA2.5
  • AA3.1, AA3.2, AA3.3
  • AA4.1, AA4.2, 4.3, AA4.4
  • AA5.3, AA5.4, AA5.5, AA5.6,
  • AA6.1
At the end of this course,students will be able to
- Describe the physical behavior at play, and use appropriate models, in advanced semiconductor devices and in a wide range of temperature and frequency.
- Use simulation and accurate characterization tools of semiconductor devices.
- Model new devices in the perspective of forthcoming courses and master projects.
Lectures are given interactively and are based on the themes presented above. They are complementary to the written notes and references below as they give a different perspective and are based on student questions.
The project is an extension of the lectures and allows a deeper understanding of advanced devices. It relies on a bibliographic review of a specific subject chosen by the students (groups of 1 to 3), and/or the analysis of experimental data and modelling, depending on ressources available in the lab.
