Film stress of chemical vapor deposited silicon dioxide films was evaluated. All of the deposited films show tensile intrinsic stresses. Oxygen partial pressure dependence of the intrinsic stress is very close to that of deposition rate. The intrinsi

The effects of annealing processes performed in inert gas and of electrode materials on SrBi2Ta2O9 (SBT) films are investigated to estimate the sensitivity and robustness of their dielectric and ferroelectric properties. SBT films 200-nm thick were s

Dual-type octahedral void defects were found in Czochralski silicon in 1995. This was a trigger for a “renaissance” in the field of Si crystal investigation as well as a breakthrough toward the new stage of the next-generation Si-microelectronics

During the past 20 years, there have been several breakthroughs regarding the research on grown-in defects in Czochralski silicon (CZ-Si) for commercial use. The presence of oxide defects originating in CZ-Si was first reported in 1979, and it was so

Octahedral void defects are widely recognized to be a cause of crystal-originated particles, flow-pattern defects, laser-scattering tomography defects, and oxide defects. Their structure has been characterized in detail and the dependence of their ge

We have evaluated the electrical characteristics of silicon-nodule-related via failures in the aluminum interconnects of silicon integrated circuits. Current-voltage measurements indicated that the conduction mechanism follows Ohm's law. The resistan

We found that thermal oxidation of (001)-oriented Czochralski silicon produces oxide ridges which surround the oxide pits above the grown-in defects (or octahedral void defects), whereas thermal oxidation of (111)-oriented Czochralski silicon produce

We have found that thermal oxidation of Czochralski-grown-silicon substrates produces local circular stains around octahedral void defects. A plan view revealed that an octahedral void defect is situated near the center of a circular stain. Oxidation

Annealing characteristics of plasma-enhanced chemical vapor deposited silicon nitride films have been evaluated. Annealing temperature dependence for N–hydrogen bonds decreases monotonically with increasing temperature, while that for Si–hydrogen

The dependence of the density of defects in the oxide on Czochralski silicon substrates on its thickness is discussed quantitatively in terms of the shape and the size of the octahedral void defects. Oxide thinning at corners of the void defects may
