Nano and micro technologies

Understand the specificities of the multidisciplinary field of nanoscience and micro/nanotechnology by combining two complementary approaches, bottom-up and top-down. These two approaches will result in cross-disciplinary teaching in the fields of chemistry, physics and biology. The aim is to provide students with solid skills in these different sectors, as well as a specialization that they can use to their advantage in the workplace. This specialization is taught in English.

General knowledge (from the first two years of the ENSCBP Chemistry-Physics department) in the fields of physics and chemistry.

Part 1: Manufacturing and characterization techniques (partially shared with PC0MSSCE)

Objectives

Acquire strong, indispensable skills in micro- and nano-fabrication techniques, as well as the techniques now commonly used to characterize the nanostructures or nano-objects formed. Alongside traditional courses, practical work in microscopy and biotechnology will enable students to apply and consolidate their theoretical knowledge.

Objectives 

Discover various nano-objects and nanomaterials (nanotubes, nanofibers, nanoparticles, organized nanostructures, etc.) and their specific properties linked to their characteristic sizes. Master these nano-objects for their future use in innovative applications, and delve into the industrial aspects of their manufacture. Be acutely aware of the toxicological and environmental aspects of nanomaterials. Learn how to work in a clean room during a one-week internship at AIME in Toulouse, during which students experience the technologies involved in manufacturing electronic components, integrated circuits or microsystems, as well as the characterization tests associated with the various stages. This internship is a way of putting into practice the different technologies seen in previous years or courses.

Part 4: Industrial project 

Objectives

The Industrial Project enables students to work on a topical subject proposed by an industrial company in line with their specialization. This involves respecting a given set of specifications and meeting the various objectives set by the industrialist. The subject can be a bibliographical and/or technology watch topic.
The work carried out must use the industrial project management approach.
This is a professionalizing project, which may lead to an internship with the sponsoring company.

Contents

Students work in groups of 3 or 4. Each project group must work in consultation with the company sponsoring the project and with the project's tutor (each group is specifically supervised by a teacher from the specialization module).
At the end of the project, each project group must submit a written report of no more than 20 pages.
