Integration of ultrathin silicon chips
In this work the mechanical behavior of ultrahin silicon chips during gold/tin bump reflow and during flip chip soldering onto polyimide tapes was analyzed. The experiments and analyses are a contribution to the research area of flex systems based on solder connections between extremely thin chips …

Design and optimization of ultrathin silicon field effect transistor's for sensitive, electronic-based detection of biological analytes
… in the semiconductor and communications markets. Silicon nanowires are of great interest for point-of-care testing as they are a CMOS compatible structure, require the use of no labels, and are highly sensitive to the binding of molecules to their surfaces. This is due to the large surface area to …

Studies of Field -Induced Stress on Ultrathin Layers of Silicon Dioxide on a Silicon Substrate
We present here the results of an STM study of ultrathin silicon dioxide layers on a silicon substrate. We have found that under certain conditions, structures subjected to field-induced stress with the STM exhibit changes in their conductivity which we believe are evident in the images as the …

Nanoscale structure and transport : from atoms to devices
… Self-trapped hole structures in amorphous silicon dioxide are investigated in order to connect the behavior of hole currents to atomic-scale structures. Calculations on a paired-oxygen analogue to the ... center show that such a configuration does not result in a metastable trapped-hole …

Black silicon and its applications in photovoltaics and biosensing
Black silicon was produced with a lithography-free three-step plasma etching method. The nanocone forest on the silicon surface makes the silicon look black. Its applications in photovoltaics and biosensing were demonstrated by experiments. For photovoltaics, sub-100 nm nanocone forest was produced …
