[Thesis]

Study of inter-pixel surface states for semiconductor X-ray detectors

Offer N°: SL-DRT-15-0373

Start date: 1 Oct 2015

As part of its activities in medical imaging, LETI has developed over several years a new technology of detectors based on CdTe/CdZnTe semiconductor material, in order to offer new performance X-ray and gamma-ray imaging for different applications like radiology, CT scanner, gamma-camera, and non-destructive testing. The first prototypes have shown an interest in improving image quality and dose reduction.



[Thesis]

SPAD for High resolution depthmap

Offer N°: SL-DRT-15-0345

Start date: 1 Oct 2014

SPAD (Single Photon Avalanche Diode) is the more accurate TOF (Time Of Flight) distance measurement. Some specific issues appear when SPADs are used in matrix to get a depthmap of the scene: sensitivity, compactness, internal speed and integration density are of major concern. Existing SPAD matrix do not allow a large diffusion, although the need is great to improve embedded image treatment efficiency.



[Thesis]

Modeling of spintronics phenomena in magnetic nanostructures

Offer N°: SL-DSM-15-0340

Start date: 1 Oct 2015

The ultrafast dynamics of the magnetization in magnetic nanostructures is a key factor for designing new miniaturized electronic devices (e.g. magnetic memories, integrated microwave components, magnetic logic gates,…). To build the active part, concepts such as spin transfer torque or spin-orbit torques are intensively studied experimentally.



[Thesis]

Characterization and modeling of mechanical properties of thin films for 3D Integration - Application to plastic materials and large deformations

Offer N°: SL-DRT-15-0299

Start date: 1 Sep 2015

During a previous thesis, SIMAP and LETI have developed a mechanical calculation tool called SigmaPeps which is implemented in MATLAB. It provides access to levels of strains and stresses generated during process steps (deposits, thermal treatments, grinding ...) which allows to act upstream manufacturing sectors by focusing on the choice of materials and ensure the integrity of a device.
