  1. 16. AlN and High-k Thin Films for IC and Electroacoustic Applications

    Author : Fredrik Engelmark; Ivan Petrov; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

    Abstract : Further, a highly selective dry etch process for etching Al on AlN has been developed for the fabrication of MIM, MIS, SAW and BAW test structures for electrical and electroacoustic characterization of the films. A dielectric constant of 10 for AlN and 25 for Ti doped Ta2O5 have been measured. READ MORE

  2. 17. Synchrotron X-ray based characterization of technologically relevant III-V surfaces and nanostructures

    Author : Andrea Troian; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; III-V semiconductors; high-k oxides; passivation; doping; XPS; AP-XPS; SPEM; XRF; full field X-ray diffraction microscopy; Fysicumarkivet A:2019:Troian;

    Abstract : Innovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) studied here.

    Abstract : Atomic layer deposition (ALD) is an outstanding deposition technique to deposit highly conformal and uniform thin films with atomic precision. In particular, ALD of transition metal oxide layers from metal amido complexes and water finds its way in several technological fields, including green energy devices and in the semiconductor industry.
