No specific pedagogical methods are dedicated to explain the specificity of CMOS Active Pixel Sensor (APS) technologies. Nevertheless, this technology of image sensing is wide-spread in today's life and needs a good understanding on behalf of our students in microelectronics. This paper proposes a toolkit implemented with MATLAB. This toolkit can help the student to find out the architecture of an...
We investigate the occurrence of Multiple Bit Upsets in commercial SRAMs of 4Mbits and 32Mbits when irradiated with neutrons. The devices were irradiated at TSL facility with QMN beams of energies from 50MeV to 180MeV. Experimental data demonstrate that the dynamic-stress increases SRAMs sensitivity as well as MBUs occurrence for both the memory types. We also show that both SEU and MBU cross section...
Generally, in the studies of microelectronics engineer the approach of IC testing remains very theoretical. Only few concrete practices are commonly done and generally laboratory experiences are limited to the use of CAD tools. For this purpose, in our teaching department, we develop an experiment allowing a concrete learning of IC testing dedicated to the test of commercial memory chips. Through...
In this paper, we propose a technique for the detection of neutrons in atmospheric environment developed in the framework of HAMLET project. This technique relies on the sensitivity of SRAM cells to particle radiation. In particular, we introduce a system based on a memory test bench that records the neutron reactions in memory devices. This system presents a good rate of flexibility from different...
This paper presents the results of SPICE simulations of terrestrial radiation induced effects on SRAM cells in which resistive-open defects are introduced. This kind of defect is difficult to be detected with standard manufacturing tests. Although the presence of the defect may not affect the memory functionality when not exposed to radiation, it alters the radiation induced error rate of the cell...
Piezoelectric materials are widely used for many applications such as sensors, actuators. Today, their integration in microelectronics processes like CMOS requires the development of advanced realistic behavioral models. Until now, these models were limited to only one ceramic's operation mode, i.e., thickness or planar. Moreover, the robustness of piezo-electronic systems cannot be adequately addressed...
In classical microelectronics engineer curriculum, students have to acquire skills in device physics as well as in analog and digital IC design. As a rule, each course is illustrated in a dedicated CAD tools laboratory. Over time, this method leads to a compartmentalizing of the teaching by putting conceptual barrier in the student's mind. This article proposes a laboratory in which students can mix...
In this paper, we propose a technique for the detection of neutrons that relies on the sensitivity of SRAM cells to particle radiation. In particular, we introduce a system based on a memory test bench that records the neutron reactions in the memory array. This system allows a good flexibility from different points of view. It is conceived to be modular, programmable, low power consuming and portable...

The widespread use of piezoelectric materials in an increasing number of applications requires the development of advanced realistic electrical models. Until now, models were limited taking into account only one ceramic's operation mode, i.e., thickness or planar. On the other hand, it establishes that the robustness of the piezo-electronic systems is likely to weaken if the models making it possible...
In electrical engineering graduate schools, integrated circuit design is usually taught through lectures, tutorials, projects and labs. During these courses, the reference to electronic design automation software is essential. However, it is during the projects that the students acquire the most of their know-how in this field: since these project topics are given by industrialists or researchers,...
