Vacancy details

General information


The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.

The CEA is established in ten centers spread throughout France

Description de l'unité

CEA Tech is the world leader in technology research. The teams of research engineers are mobilized to build and transfer to industrial partners portfolios of technologies that meet the needs of the information, communication, energy and health technology sectors.

The Leti, one of CEA Tech's institutes, focuses on micro and nano technologies and their applications to wireless communication systems and components, biology and health, imaging, and Micro-Nano Systems (MNS )

The Silicon Components Division carries out research on nanoelectronics and heterogeneous integration on silicon and is focusing on two mains areas: on-going shrinking of CMOS devices to extend Moore's Law for faster, less-expensive computing power, and the integration of new capabilities into CMOS, such as sensors, power devices, imaging technology, and new types of memory, to enable new applications.

LCTE laboratory (Test and Electrical Characterization) is part of LETI's Department of Silicon Components (DCOS) and is in charge of the functional test and the electrical characterization of semiconductor devices (CMOS, power, memory, imagers...) realized on 200 or 300mm wafers fabricated in LETI clean rooms or by our industrial partners. A fleet of measurement equipments is used to report on the functionality of devices, compare technological variants and analyze in detail the physical mechanisms governing their performance and reliability.

Job description

CEA is looking for a research engineer for the development, execution and analysis of tests on innovative image sensors. An important focus will be on the execution of ultra-short transient measurements (<1ms), and the analysis of their evolution during pixel ageing (electrical, light and temperature stress). Such analysis should make it possible to map the defects induced by the fabrication and ageing of the pixels (energy, concentration, time constants), and thus lead to a robust degradation model.

The engineer will be required to:

- develop specific test procedures (test benches remote control, implementation of complex opto-electrical sequences),

- prepare and execute opto-electrical tests, in manual or automatic mode,

- format and analyze test data for internal and / or external communication,

- analyze test data, provide clear conclusions about the physical mechanisms governing pixel performance and reliability,

- quantify the degradation of the pixels (defects) and propose a reliability model.


Applicant Profile

Higher education, engineer or doctorate, you have a 1 to 5 years' experience in the field of testing, electrical characterization and reliability of electronic components. You have a knowledge of the micro and nanoelectronic devices and technologies essential to the relevance of the tests. An imager background is also desired but not required.
You are familiar with microelectronic electrical characterization equipments (Keysight, Tektronix / Keithley, TEL, Cascade, ...) and you master one or more object-oriented programming languages, especially Python.
The experience of teamwork and the mastery of English are essential. You have the sense of organization and innovation and are force proposing new characterization strategies. You are able to effectively summarize your work for internal or external communication.
