36. Heterogeneous 3D Integration and Packaging Technologies for Nano-Electromechanical Systems
Sammanfattning : Three-dimensional (3D) integration of micro- and nano-electromechanical systems (MEMS/NEMS) with integrated circuits (ICs) is an emerging technology that offers great advantages over conventional state-of-the-art microelectronics. MEMS and NEMS are most commonly employed as sensor and actuator components that enable a vast array of functionalities typically not attainable by conventional ICs. LÄS MER
37. Microwave CMOS LNAs and VCOs - Using Passives On-Chip, Above Chip, and Off-Chip
Sammanfattning : The performance of LNAs and VCOs is of large importance to the complete wireless communications system. To achieve sufficient performance in microwave applications, LNAs and VCOs have therefore up to now mostly been manufactured in advanced and expensive semiconductor technologies. LÄS MER
38. Low temperature transfer bonding for MEMS. Utilizing and characterizing oxygen plasma assisted direct wafer bonding
Sammanfattning : Transfer bonding enables the integration of devices, e.g. integrated circuits (ICs) and transducers, fabricated using processes and/or designs that are not compatible with each other as well as double sided micromachining of thin films. LÄS MER
39. On-chip terahertz characterisation of liquids
Sammanfattning : Spectroscopy at terahertz frequencies can be used in a wide range of applications including radio-astronomy, pharmaceutical manufacturing control, and the study of processes in molecular biology. Biomolecular samples should preferably be studied in their native environment, water, however, water poses extreme attenuation for THz-frequency waves, deteriorating or even impeding analysis using these waves.

40. Planar-Goubau-line components for terahertz applications
Sammanfattning : Terahertz-wave technology has a broad range of applications, including radio astronomy, telecommunications, security, medical applications, pharmaceutical quality control, and biological sensing. However, the sources, detectors, and components are less efficient at this frequency band due to parasitic effects and increased total losses, which hinder the performance of terahertz systems.
