Design of test structures for electrical characterization of performance for high density 3D interconnects and technological development
Offer N°: SL-DRT-15-0627
3D interconnects are used for microelectronic vertical chip assembly possibly with different technology nodes. The purpose is to increase electrical performance of integrated circuits. 3D interconnects under development in the laboratory (CEA-LETI) address both internal skills and industrial collaborations. The typical dimensions of the metal resistors are in the range 1 – 5 µm.
Indirect X-ray photon counting imager for color medical radiology
Offer N°: SL-DRT-15-0614
As part of its activities in medical imaging, Leti has developed over several years several detectors technology, in order to propose new performance in X-ray imaging for different applications like radiology and X-ray CT scanner, gamma-camera, and for non-destructive testing. The first prototypes have shown a great interest in improving the image quality and dose reduction.
Low temperature Electron-beam-induced current (EBIC) characterization of 3rd gen IR detectors
Offer N°: SL-DRT-15-0605
The optronic departement of LETI (DOPT) is a key laboratory in the field of high performance quantum IR imaging. We work in close collaboration with Sofradir, today a world leader manufacturer of high performance IR focal plane arrays. The increasing complexity of those IR retina (megapixel formats, ultra-fine pixel pitches, multicolor detection, and high operating temperature) calls for new advanced characterization methods.
Adequate approximate computing for high energy-efficiency in Internet of Things applications
Offer N°: SL-DRT-15-0320
Approximate and inexact computing are non-conventional paradigms that allow bounded errors in calculation to obtain significant benefits in energy, performance, or circuit area . The thesis will bring these paradigms one step further, to adequately-approximate computing, by investigating dynamic accuracy adaptation. The candidate will propose methods to control hardware inexactness in software, in order to just meet the accuracy demands of applications, under strong energy constraints.
