In this paper, we present a thorough physical-chemical analysis of an engineered PCM stack, where the integration of C-doping and the use of a Ti top layer allow obtaining an Amorphous As-Deposited (A-AD) phase stable against Back End-Of-Line (BEOL) thermal budget. This PCM stack is then integrated in devices, which are extensively tested in order to validate a novel pre-coding technique compliant...Show More

A detailed study of performance in uniaxially-strained Si nanowire (NW) transistors fabricated by lateral strain relaxation of biaxial SSOI substrate is presented. 2D strain imaging demonstrates the lateral strain relaxation resulting from nanoscale patterning. For the first time, an improvement of electron mobility in SSOI NW scaled down to 10nm width has been successfully demonstrated (+55% with...Show More

In this work, a detailed study of the physical mechanisms governing the Source Side Injection programming in ultra-scaled (down to 20nm) SiN split-gate memories is presented. Experimental measurements coupled to static and dynamic TCAD simulations are shown. In particular, we claim that adjusting the select gate voltage in moderate inversion allows for the optimization of the compromise between hi...Show More

2012 4th IEEE International Memory Workshop
Year: 2012 | Conference Paper |
In this paper, we investigate the electrical performance of Phase-Change Memory (PCM) devices at high operating temperature (up to 180°C). We perform a detailed experimental analysis on μtrench PCM cells with different dimensions. We show that the high temperature strongly impacts the programming curves, by linearly decreasing the threshold voltage and decreasing the RESET current. Furthermore, th...Show More
