[IEEE 2019 International Conference on Electronics Packaging (ICEP) - Niigata, Japan (2019.4.17-2019.4.20)] 2019 International Conference on Electronics Packaging (ICEP) - High-speed High-density Cost-effective Cu-filled Through-Glass-Via Channel for Heterogeneous Chip Integration
摘要： A topside Cu-filled through-glass via ("Cu bridge") is presented as a novel transmission channel. The simulated signal transmission loss of the Cu bridge was as low as 0.04 dB at a signal frequency of 18 GHz, corresponding to the PCI Express 5.0 bus standard. Its signal transmission loss was less than 0.13 % in a typical long-reach SerDes channel with a loss of 30 dB. The minimum pitch of the Cu bridge was as narrow as 100 μm, which meets the requirements for increased signal I/O. The simple few-step fabrication of the Cu bridge effectively reduces the cost of manufacturing glass interposers. This is a great advantage compared to silicon interposers, which require a complicated process to fabricate Cu through-silicon vias. A glass substrate semi-additive and embedded with Cu bridges supports damascene-based redistribution layers, which increases the number of potential packaging configurations. This Cu bridge is thus a promising approach to next-generation heterogeneous integration based on 2.nD interposers.

XXX. Messtechnisches Symposium || Scannerbasierte, koaxiale Topographiemessung auf Basis der kurzkoh?renten Interferometrie für die Lasermaterialbearbeitung bei 515 nm
摘要： Angesichts immer gr??erer Anforderungen an Prozessgenauigkeiten und immer enger gefassten Toleranzfenstern bei der Lasermikrostrukturierung, erfahren die exakte überwachung von Laserprozessen und die anschlie?ende Qualit?tssicherung der laserstrukturierten Produkte einen immer h?heren Bedarf. Um diesen zu decken besch?ftigt sich dieses Paper mit der Entwicklung eines ganzheitlichen Ansatzes zur scannerbasierten, koaxialen Topographiemessung durch die Integration eines hochgenaues Inline-Messsystem in die vorhandenen Optiken einer Laseranlage. Die Kombination und Implementation des Laserbearbeitungsstrahls und des Messstrahls durch die gleichen Optiken soll dabei die M?glichkeiten einer Echtzeit-Prozessrückführung der Messdaten zur Realisierung eines adaptiv geregelten Lasermikrostrukturierungsprozesses er?ffnen. Dabei wird in dieser Arbeit der Einfluss der einzelnen Systemkomponenten der Laseranlage auf ihren Einfluss auf optische Aberrationen für den Messstrahlengang erl?utert. Daneben werden L?sungen für die Optimierungen der Teilsysteme zur Verringerung der Aberrationen erarbeitet und in einem Demonstratoraufbau als Offline Messsystem mittels Applikationsbeispielen aus der Lasermikrostrukturierung evaluiert.

[IEEE 2019 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America) - Gramado, Brazil (2019.9.15-2019.9.18)] 2019 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America) - Estimation of the Probability of Integration of Photovoltaic Microgeneration using Fuzzy Logic
摘要： There is a great diversification of the sources used for the generation of electric energy in Brazil, which was accentuated with Normative Resolution 482 of 2012, of the National Agency of Electric Energy (ANEEL). From this resolution and the creation of some governmental policies, the participation of the Distributed Photovoltaic Generation (DPG) in the electric system began to be made feasible and its penetration levels tend to increase continuously. Therefore, it is necessary to develop methods capable of estimating the potential of DPG integration in the distribution system, so that the distributor can adapt it when necessary and carry out more reliable planning. Therefore, this paper proposes a methodology, based on fuzzy logic, to estimate the probabilities of DPG insertion in low voltage networks. The variables adopted reflect the trends in the electricity sector, such as energy prices, the cost of photovoltaic systems (PVS), the incentives given to the DPG, the attractiveness of the DPG and the time of return on investment. The output of the fuzzy inference system presents a probability of integrating the DPG into the current distribution system.

Ultraviolet Nanosecond Laser Annealing for Low Temperature 3D-Sequential Integration Gate Stack
摘要： For the top tier in a 3D sequential integration, we propose a low temperature gate first approach in which an in-situ doped amorphous silicon layer is deposited at 475°C then subsequently converted into a polycrystalline film using ultraviolet nanosecond laser annealing. We demonstrate the ability to obtain a low resistance poly-Si gate for the top transistors within a thermal budget expected to preserve the bottom devices electrical performance.

Widely Tunable Electro-Absorption Modulated V-Cavity Laser
摘要： We report a widely tunable V-cavity laser monolithically integrated with an electro-absorption modulator (EAM). The device shows a 41-nm wavelength tunability covering 51 channels at 100GHz spacing on the ITU grid, with a side-mode suppression ratio (SMSR) higher than 47 dB. Error-free transmission over 50 km standard single-mode fiber at 10 Gb/s is demonstrated at all wavelengths over the tuning range. The integrated EAM exhibits a dynamic extinction ratio higher than 12.5 dB. The bit-error-rate measurements show a power penalty less than 3 dB for 50-km transmission. The results demonstrate that this ultra-compact and regrowth-free electro-absorption modulated tunable laser can be a cost-effective transmitter solution for DWDM metropolitan and access networks.

[IEEE 2019 IEEE Industry Applications Society Annual Meeting - Baltimore, MD, USA (2019.9.29-2019.10.3)] 2019 IEEE Industry Applications Society Annual Meeting - Elimination of Phase Unbalance in Cascaded Multilevel Converters for Large-Scale Photovoltaic Grid Integration
摘要： Cascaded H-bridge converters (CHB) are ideal candidates for large-scale photovoltaic (PV) power plants because of their modular structure and the absence of bulky line frequency power transformer. To eliminate leakage current, isolated dc-dc converters are needed to connect the PV arrays to the H-bridges of CHB. These dc-dc converters extract maximum power from each PV array independently. Under partial shading conditions, the power generated in the three phases of CHB is different, leading to an unbalance in the grid currents. The existing methods to balance the grid currents require the converter to be overrated or operate at reduced PV power. So a new topology is proposed to distribute the power equally among the three phases of CHB without overrating the converter or reducing the PV power. This is achieved by using high-frequency transformers each having one primary and three secondaries. Simulation results are presented to validate the proposed topology.

Simulated photo-degradation of dissolved organic matter in lakes revealed by three-dimensional excitation-emission matrix with regional integration and parallel factor analysis
摘要： Simulated photo-degradation of fluorescent dissolved organic matter (FDOM) in Lake Baihua (BH) and Lake Hongfeng (HF) was investigated with three-dimensional excitation-emission matrix (3DEEM) fluorescence combined with the fluorescence regional integration (FRI), parallel factor (PARAFAC) analysis, and multi-order kinetic models. In the FRI analysis, fulvic-like and humic-like materials were the main constituents for both BH-FDOM and HF-FDOM. Four individual components were identified by use of PARAFAC analysis as humic-like components (C1), fulvic-like components (C2), protein-like components (C3) and unidentied components (C4). The maximum 3DEEM fluorescence intensity of PARAFAC components C1eC3 decreased by about 60%, 70% and 90%, respectively after photo-degradation. The multi-order kinetic model was acceptable to represent the photo-degradation of FDOM with correlation coefficient (Radj2) (0.963e0.998). The photo-degradation rate constants (kn) showed differences of three orders of magnitude, from 1.09(cid:1) 10(cid:3)6 to 4.02 (cid:1) 10(cid:3)4 min(cid:3)1, and half-life of multi-order model (Tn1=2) ranged from 5.26 to 64.01 min. The decreased values of fluorescence index (FI) and biogenic index (BI), the fact that of percent fluorescence response parameter of Region I (PI,n) showed the greatest change ratio, followed by percent fluorescence response parameter of Region II (PII,n), while the largest decrease ratio was found for C3 components, and the lowest Tn1=2 was observed for C3, indicated preferential degradation of protein-like materials/components derived from biological sources during photo-degradation. This research on the degradation of FDOM by 3DEEM/FRI-PARAFAC would be beneficial to understanding the photo-degradation of FDOM in natural environments and accurately predicting the environmental behaviors of contaminants in the presence of FDOM.

Overview on Monolithically Integrated Arrays of Microtubular Vertical Resonators on Photonic Waveguides for Optofluidic Applications
摘要： A novel platform for optofluidic applications is realized by monolithic integration of an array of ultra-compact three-dimensional (3D) vertically rolled-up microtube ring resonators (VRU-MRRs) with polymer waveguides. The on-chip integrated system is realized by rolling up 2D differentially strained TiO2 nanomembranes into 3D microtubular cavities on a nanophotonic chip. Whispering-gallery modes are observed in the telecom wavelength range, and their spectral peak positions shift significantly when measurements are performed while immersing the tubes or filling their hollow cores with water. The achievement of this work opens up fascinating opportunities to realize massively parallel optofluidic microsystems with exceptional multi-functionality for analysis of biomaterials in lab-in-a-tube systems on a single chip.
