Full textIn semiconductor industry, the More-than-Moore approach is a key enabler for enhanced system performance, better integration and improved diversity of applications. Within the focus area of RF/microwave systems, it is essential to develop different functionalities which are optimized for various requirements like linearity, losses, sensitivity etc. While Silicon-on-Insulator (SOI) technology offers competitive solutions for RF/microwave market, it has been demonstrated in previous studies that SOI substrate engineering results in further performance gains. In this context, the specific goal of our work is the investigation of substrate processing of SOI RF functions using femtosecond laser ablation. The objective is to remove silicon handler substrate under the active area of the RF functions to obtain SOI membranes which have reduced RF losses and improved linearity. In this work, we have developed the Femtosecond Laser Assisted Micromachining and Etch (FLAME) process to suspend RF functions integrated on a SOI substrate. A high specific ablation rate of 8.5 x 106 µm3 s-1 has been achieved to produce membranes with a surface area ranging from few hundreds µm2 to several mm2. RF characterization has been performed on different suspended RF functions: switches, inductors and low noise amplifiers (LNA). A comparison with high-resistivity SOI substrates shows superior performance of RF functions integrated in suspended membranes. For the SP9T switch, harmonic distortion measurements showed an improvement of 23 dB and 6 dB of the second and third harmonic, respectively. Small signal measurements of inductors on membranes revealed a near doubling of the quality factor of inductors up to 3.2 nH. Substrate removal of input matching inductor on LNA resulted in reduction of noise figure by ~0.1 dB. These results highlight the great potential for use of substrate processing for improvement of RF performance in CMOS technology. In addition, for short loop analysis needs, the FLAME method allows to quantify the influence of the substrate on losses and linearity very quickly without the need for total substrate removal. Another distinctive advantage of this methodology is the ability to quantify the substrate effect on a full circuit by suspending a specific component while keeping other components unaffected. The developed fabrication methods are equally usable for sensor applications on SOI technology, which provides an overall added value in line with the More-than-Moore paradigm

Full textThe power amplifier market for mobile phone handsets is currently dominated by III-V semiconductors, the PHEMT and HBT GaAs transistors being used for the power amplifiers and the antenna switches respectively. However, this situation is evolving with the release of Silicon-On-Insulator (SOI) technologies which allow the integration of both the power amplifier (with LDMOS transistors) and the antennae switches (with CMOS transistors or MEMS). The performances of the polysilicon gate LDMOS transistors, integrated in CMOS technologies, limits however the operatinq frequency of the power amplifiers to below 2 GHz. The aim of the thesis work presented in this manuscript is to extend the applications of LDMOS transistors to the wireless communication networks operating in the 3 to 5 GHz frequency range. In this perspective, an initial study on different SOI and bulk substrates concluded that thin SOI substrates penalize the performances of RF LDMOS transistors mainly because of the increase of the self-heating effect. A second study focused on the transistor layout shows that a change in the gate contact scheme can significantly increase the small signal performances but the improvement of the large signal performances is more moderate. Finally, a more advanced study which aims to replace polysilicon gates by metal exhibited that the co-integration of conventional CMOS transistors with metal-gate LDMOS transistors is possible

Full textSince 2000, Silicon Carbide (SiC) power devices have been available on the market offering tremendous performances. This leads to really high efficiency power systems, and allows achieving significative improvements in terms of volume and weight, i.e. a better integration. Moreover, SiC devices could be used at high temperature (>200°C). However, the SiCmarket share is limited by the lack of reliability studies. This problem has yet to be solved and this is the objective of this study : aging and failure mechanisms on power devices for high temperature applications. Aging tests have been realized on SiC MOSFETs. Due to its simple drive requirement and the advantage of safe normally-Off operation, SiCMOSFET is becoming a very promising device. However, the gate oxide remains one of the major weakness of this device. Thus, in this study, the threshold voltage shift has been measured and its instability has been explained. Results demonstrate good lifetime and stable operation regarding the threshold voltage below a 300°C temperature reached using a suitable packaging. Understanding SiC MOSFET reliability issues under realistic switching conditions remains a challenge that requires investigations. A specific aging test has been developed to monitor the electrical parameters of the device. This allows to estimate the health state and predict the remaining lifetime.Moreover, the defects in the failed device have been observed by using FIB and SEM imagery. The gate leakage current appears to reflect the state of health of the component with a runaway just before the failure. This hypothesis has been validated with micrographs showing cracks in the gate. Eventually, a comparative study has been realized with the new generations of SiCMOSFET

Full textA new type of light sensor called FDPix, composed of one transistor (1T) per pixel is investigated. It consists in co-integrating an FDSOI (Fully-Depleted Silicon-On-Insulator) transistor with a photodiode to enable light sensing through optical back biasing. The absorption of photons and resulting photogenerated charges in the diode will result in a Light Induced VT Shift (LIVS). The LIVS is due to a capacitive coupling between the front and back gate of the FDSOI transistor and represents the key performance metric to be extracted and optimized. In this work, the device behavior in dc and transient domains was thoroughly investigated and modeled. Although not limited to this node, all the devices tested were fabricated using 28nm node FDSOI technology. By means of TCAD simulations and opto-electrical characterization, the device parameters such as Body Factor (BF) and junction profile were optimized to improve its performance. It was found that the FDPix is in fact a dual response sensor. It exhibits a linear response at low light intensity which results in high sensitivity, and a logarithmic response at higher intensities that ensures a high dynamic range (DR) of more than 120dB. The dedicated developed model is implemented in SPICE environment for circuit design. New pixel circuit in analog and digital domain, based on the FDPix were designed, fabricated, and tested. The results obtained and presented in this work, shows the potential of using the FDPix sensor for smart, highly embedded, low power image sensors for More-than-Moore applications
