Texto completoThis PhD thesis focuses on technological challenges related to the development of advanced transistors (FinFET, FDSOI), where the etching of thin films reveals several issues. In particular, the etching of silicon nitride spacers should be achieved with a nanoscale precision without damaging the underlayers, a step which cannot be addressed by conventional CW plasmas. To overpass this limitation, an innovative approach was recently developed (so-called Smart Etch), which is based on light ion implantation and composed of two steps. First, the material to be etched is modified by exposure to a hydrogen (H2) or helium (He) ICP or CCP plasma; in a second step, the modified layer is selectively removed using wet etching or gaseous reactants only. To support the fundamental understanding of the first step and assist the development of this new technology, molecular dynamics (MD) simulations were performed to study the interaction between silicon/silicon nitride films and hydrogen/helium plasmas. MD was used to investigate how the substrates modification is affected by the ion energy, the ion dose, the ion composition or the radical-to-ion flux ratio (in the case of a H2 plasma). In agreement with experiments, simulations of He+ or Hx+ (x=1-3) ion bombardment of Si/SiN show that a self-limited ion implantation takes place with a surface evolution composed of two stages: a rapid volume modification (with no etching) followed by a slow saturation and the formation of a stable He- or H- implanted layer at steady state. The mechanisms of ion-induced damage (Si-Si or Si-N bond breaking, He or H2 trapping/desorption, SiHx (x=1-3) complex creation) are investigated and allow to bring new insights to both the Smart Cut and Smart Etch technologies. Si/SiN exposure to various H2 plasma conditions (with both Hx+ ions and H radicals) was then studied. In this case, a self-limited transformation is observed but the H-modified layers are simultaneously etched during the ion implantation, at a rate ~10 times smaller for SiN compared to Si. Simulations show that to modify Si/SiN thin films with a nanoscale precision by H2 or He plasmas, both the ion energy and the ion flux have to be controlled very cautiously. In particular, low ion doses, where the substrate evolution is in rapid modification stage, must be avoided since the substrate evolution cannot be precisely controlled. In H2 plasmas, high ion energies induce thicker modified layers but smaller and less homogeneous hydrogenation rates. The ion composition and the radical-to-ion flux ratio Γ must be considered as well, since the etch rate increases with Γ, compromising even the possibility to achieve a Smart Etch of silicon. The MD simulations performed in this thesis enable to clarify various unexplained phenomena seen in the Smart-Etch experimentally, and reveal some possible issues in this new process. In the end, a range for plasma parameters is proposed to optimize this first step of the Smart Etch process and to control the modification of SiN with a sub-nanoscale precision

Continued pursuit of better superconducting devices and an understanding of how the focused ion beam evolves in a complex material are the primary motivations behind this work. The materials of interest are MgB2 and Co-doped Ba122. Superconducting properties of MgB2 were discovered in 2001. It is the first superconductor recognized as a multigap superconductor. Owing to its high Tc of ~39K, electronic circuits based on this material are expected to operate at a much higher temperature (~25 K) than low-temperature superconductors, using compact cryocoolers. Co-doped Ba122 is also a multigap superconductor which belongs to Fe-based superconductor (FeSC) family. The undoped Ba122 compound is a metal exhibiting antiferromagnetism which coexists with superconducting phase up to a certain doping level. The optimally electron-doped BaFe2As2 exhibits the transition temperature Tc of ~21 K which corresponds to the top of the “dome” in the phase diagram. While the Fe-based SC may not signify a particular advance in terms of practical applications, many unique aspects make them worth studying. In particular, the superconducting gap symmetry and structures which appear to be quite different from family to family and not yet fully understood. We report on investigating the normal-state, and superconducting properties of Co-doped BaFe2As2 and MgB2 thin films irradiated at room temperature using a 30-keV focused He+ ion beam in helium ion microscope (HIM). R-T measurement was carried out to extract the dose dependence for Tc and resistivity p0 of the irradiated region. We observed an increase in p0 and a decrease in Tc down to complete suppression of superconductivity for both materials, although the trend of the changes was quite different. In addition, for Ba122, the data for ΔTc ⁄ Tc0 versus measured change in resistivity favors s± over s++ symmetry. Using TRIM software, the projected range and the damage density distribution of the He+ ions were tracked in the samples. Single track irradiation sites for MgB2 sample were characterized using FIB extraction/TEM. The TEM micrographs reveal the subsurface damage density contours that evolve with increasing dose. The Josephson effect is a unique phenomenon that gives direct access to the phase difference 𝜑 of the macroscopic wave functions that describe the superconducting state. Josephson junction is also appealing for engineering application in superconducting electronics. Having found the dose at which complete suppression of Tc occurs from the first part of the study, a fabrication process was developed to produce planar Josephson junctions from MgB2 and Co-doped Ba122. The Josephson coupling across the barrier for both materials was observed. MgB2 Josephson junctions showed resistivity shunted junction (RSJ) I-V curve with excellent uniformity and reproducibility. We have also demonstrated tens of planar MgB2 Josephson junctions operating coherently in series arrays. 60 Josephson junction series arrays successfully developed with less than 4% spread in critical current at 12 K. Under microwave radiation, flat giant Shapiro steps up to 150 μA width appear at voltages Vn=NnΦ0f, where N is the number of junction in the array, 𝑛 is an integer representing Shapiro step index, and f is the applied microwave frequency. The uniformity and close spacing of JJs in the arrays are significantly better than MgB2 multi-junction devices made by other techniques. It has been a huge success in showing the feasibility of this technology for pursuing superconducting digital electronics, Josephson voltage standards and arbitrary function generators in particular, in MgB2 with ≥ 20K operating temperature.

Abstract This experiment, employing the radio-frequency (rf) magnetron sputtering method to deposit the ZnO thin films doping by manganese (6at%~20at%) as well as the ZnO thin films co-doping by magnesium (10at%), phosphorous (1at%) and manganese (2at%~10at%) on corning glass 1737, is mainly categorized into three parts. The first part concerns the crystal structure and microstructure. The second part explores the optical properties and the third part investigates the magnetic properties. From the experiment result, we observe that the second phase appears in the thin films of ZnO doped by manganese when the manganese content is 10at%. The band gap increases from 3.25eV to 2.64eV when the manganese content is from 6at% to 20at%. Regarding the magnetic characteristics, we find that the ferromagnetism appears in all thin films at room temperature and there exists maximum saturated magnetization when the manganese content is 15at%. From the experiment result of the ZnO thin films co-doped by magnesium, phosphorous, and manganese, the band gap increases from 3.43eV to 3.29eV when the manganese content is from 2at% to 10at%, moreover, it shows the ferromagnetic features at low temperature (10K) and room temperature. In this experiment, we observe ferromagnetism from both kinds of thin films, we can not find out the Mn3O4 phase from the TEM (Transmission Electron Microscope) analysis. The main cause of the ferromagnetism is due to the Mn2O3 phase.

In this study, hydrogenated nanocrystalline silicon (nc-Si:H) films were prepared using ICP-CVD system attached with four internal U-shaped low inductance antennas. Ar, He, and Ne gases were introduced into SiH4/H2 plasma during deposition, with the variation of gas flow rate and SiH4/H2 ratios. During deposition, an OES (optical emission spectrometer) and a plasma probe were used to characterize the conditions of plasma. The crystalllinity, structure, and Si-H bonding of these Si:H films were investigated using Raman scattering spectroscopy, XRD, and FTIR. The correlations of plasma characteristics and thin film properties were studied. It is found that the crystallinity of nc-Si:H film increases with the introduction of Ar, He, and Ne gases, especially when Ar is added. The plasma density and IH* increase with the increase of the inert gases, most likely due to penning ionization effect. The deposition rate decreases with the inert gases. This might be caused by the enhancement of hydrogen etching.
