ABSTRACT:
Toward the surface preparation of InGaAs for the future CMOS integration
   

The integration of III-V and Ge materials on Si surface causes many issues with complexity such as lattice mismatch with silicon. In particular, the surface preparation and passivation of InGaAs is very challenging, because the formation of InGaAs/high-K interface is important, but not well understood. For the systematical study of InGaAs surface during wet processes, the effect of various wet etching processes on the surfaces of binary III-V compound semiconductors (GaAs, InAs, GaSb and InSb) was studied from the viewpoints of surface oxidation, material loss (dissolution), and passivation. Based on that, further effort to understand the surface reactions on ternary InGaAs compound semiconductor was made. In addition, process sequential effect on the InGaAs surface was investigated.

ABSTRACT:

Industry Context for Semiconductor Wet Etch and Surface Preparation

 

The semiconductor industry is undergoing a transition driven by end use markets. In recent years, mobile devices have been the leading generator of growth. Now the connection of various products and machines to the internet is generating new and extensive demands for memory (storage of the data), logic (intelligent processing of the data including machine learning), and image sensing (generating visual data). Thus a division of semiconductor technology into divergent types is proceeding. Furthermore, each technology type has addressed scaling challenges with unique approaches. These lead to specific requirements for semiconductor wafer surface preparation. This paper will review the high level industry trends and how they affect surface preparation specifically.

ABSTRACT:

Putting DNA nanotechnology to work: the art of DNA origami towards innovative biosensing surfaces for medical diagnostics

 


The ability to detect extremely low concentrations of biomolecules, such as protein biomarkers, is crucial for the prevention of early-stage detection of many diseases (e.g. cancer), and therefore indispensable for improving diagnostic tools for public health. Despite all the recent technological advantages, creating a sensitive, specific, reproducible and stable biosensor is still a hurdle. One way to overcome these issues is to fully control the nano-architecture of the biosensing surface. In this talk I will demonstrate the benefits of combining DNA origami with aptamer and DNA/MNAzyme technology to create smart biosensing surfaces with improved performance to existing diagnostic tools.
