Cabbia, Marco. "(Sub)-millimeter wave on-wafer calibration and device characterization." Thesis, Bordeaux, 2021. http://www.theses.fr/2021BORD0017.
Full textPrecision measurements play a crucial role in electronic engineering, particularly in the characterization of silicon-based heterojunction bipolar transistors (HBTs) embedded into devices for THz applications using the BiCMOS technology. Thanks to ongoing innovations in terms of nanoscale technology manufacturing, devices capable of operating in the sub-millimeter wave region are becoming a reality, and need to support the demand for high frequency circuits and systems. To have accurate models at such frequencies, it is no longer possible to limit the parameter extraction below 110 GHz, and new techniques for obtaining reliable measurements of passive and active devices must be investigated.In this thesis, we examine the on-wafer S-parameters characterization of various passive test structures and SiGe HBTs in STMicroelectronics' B55 technology, up to 500 GHz. We start with an introduction of the measuring equipment usually employed for this type of analysis, then moving on to the various probe stations adopted at the IMS Laboratory, and finally focusing on calibration and deembedding techniques, reviewing the major criticalities of high-frequency characterization and comparing two on-wafer calibration algorithms (SOLT and TRL) up to the WR-2.2 band.Two photomask production runs for on-wafer characterization, both designed at IMS, are considered: we introduce a new floorplan design and evaluate its ability to limit parasitic effects as well as the effect of the environment (substrate, neighbors, and crosstalk). For our analysis, we rely on electromagnetic simulations and joint device model + probe EM simulations, both including probe models for an evaluation of measurement results closer to real-world conditions.Finally, we present some test structures to evaluate unwanted impacts on millimeter wave measurements and novel transmission line design solutions. Two promising designs are carefully studied: the "M3 layout", which aims to characterize the DUT in a single-tier calibration, and the "meander lines", which keeps the inter-probe distance constant by avoiding any sort of probe displacement during on-wafer measurements

Full textOne of the major goals of modern astrophysics is to understand the formation of our Solar System. Since low-mass protostars are suns in the making, the study of these objects and their environment provides one of the best ways to investigate the Sun's formation process and to peek in the past history of our Solar System. In my thesis, I focused on the chemistry occuring in Class 0 sources (the earliest known phases in the evolutionary scenario of low-mass protostars) by studying complex organic molecules in their envelopes. Such molecules have been discovered in IRAS16293--2422, the prototype of Class 0 sources, proving the existence of hot corinos, the inner regions of the protostellar envelope where the icy grain mantles sublimate. Some of these molecules have also been observed in comets in our Solar System, raising the question of whether (and if so, how) the chemistry of Class 0 objects affects the chemical composition of the protoplanetary disk material from which comets and other planetary bodies form. However, it is first necessary to determine whether hot corinos are ubiquitous in low-mass protostars or if IRAS16293-2422 is an exception. This was the first goal of my thesis. The approach consisted mainly in observing three Class 0 sources to search for complex organic molecules. I thereby discovered and/or confirmed three more hot corinos. The second goal was then to constrain the size of emission of complex molecules. For this, I carried out interferometric observations of the two brightest hot corinos: this emission is compact (<150 AU) with, in one of the sources, an extended component originating from the cooler, less dense outer envelope. The third goal consisted in confronting the possible formation pathways with the results of my observations to try and discriminate whether complex organic molecules form via gas-phase or grain-surface reactions. Although it was not possible to arrive at a definite answer, my data seem to favor the later formation route. Moreover, the comparison of hot corinos and their high-mass analogs, the hot cores (showing that complex molecules are relatively more abundant in hot corinos), also support grain-surface synthesis of these molecules
