1. Formation of non-metallic inclusions and the possibility of their removal during ingot casting
Sammanfattning : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.

3. Ultrathin Oxides in Metal-Oxide-Silicon Structures: Defects and Characterization
Sammanfattning : The properties of metal-oxide-silicon (MOS) structures with ultrathin oxide layers (15-30 Å) have been investigated by means of electrical characterization. The characterization methods used were mainly capacitance voltage (C-V), current voltage (I-V) and constant voltage stress (I-t) measurements. LÄS MER
4. Variations Related to Print Mottle in Starch-Containing Paper Coatings
Sammanfattning : Starch in paper coatings is known to increase the risk of print mottle in lithographic offset printing. The objective of this study was to increase the understanding of this behaviour. LÄS MER
5. Integration of thulium silicate for enhanced scalability of high-k/metal gate CMOS technology
Sammanfattning : High-k/metal gate stacks have been introduced in CMOS technology during the last decade in order to sustain continued device scaling and ever-improving circuit performance. Starting from the 45 nm technology node, the stringent requirements in terms of equivalent oxide thickness and gate current density have rendered the replacement of the conventional SiON/poly-Si stack unavoidable.
