- 1. Appl. Phys. Lett. 91, 122109 (2007) , “Determining the defect parameters of the deep aluminum-related defect center in silicon”, Philipp Rosenits, Thomas Roth, Stefan W. Glunz, and Svetlana BeljakowaThrough a combined application of two characterization methods, deep-level transient spectroscopy and lifetime spectroscopy, the lifetime-limiting defect level in intentionally aluminum-contaminated Czochralski silicon has been analyzed and a complete set of defect parameters could be obtained. This... (Read more)
- 2. Appl. Phys. Lett. 88, 253504 (2006) , “Single silicon vacancy-oxygen complex defect and variable retention time phenomenon in dynamic random access memories”, T. Umeda, K. Okonogi, K. Ohyu, S. Tsukada, K. Hamada, S. Fujieda, and Y. MochizukiThe variable retention time phenomenon has recently been highlighted as an important issue in dynamic random access memory (DRAM) technology. Based on electrically detected magnetic resonance and simulation studies, we suggest that a single Si vacancy-oxygen complex defect is responsible for this... (Read more)
- 3. J. Appl. Phys. 100, 094108 (2006) , “The effect of interfacial layer properties on the performance of Hf-based gate stack devices”, G. Bersuker, C. S. Park, J. Barnett, P. S. Lysaght, P. D. Kirsch, C. D. Young, R. Choi, B. H. Lee, B. Foran, K. van Benthem, S. J. Pennycook, P. M. Lenahan, and J. T. RyanThe influence of Hf-based dielectrics on the underlying SiO2 interfacial layer (IL) in high-k gate stacks is investigated. An increase in the IL dielectric constant, which correlates to an increase of the positive fixed charge density in the IL, is found to depend on the starting,... (Read more)
- 4. Appl. Phys. Lett. 83, 3407-3409 (2003) , “Electron spin resonance observation of trapped electron centers in atomic-layer-deposited hafnium oxide on Si”, A. Y. Kang, P. M. Lenahan, J. F. Conley Jr.We observed two paramagnetic defects in thin films of HfO2 on silicon with electron spin resonance. Both appear after photoinjecting electrons into the dielectric. Strong spectroscopic evidence links one spectrum to an O2-" align="middle"> defect. A second spectrum is... (Read more)
- 5. J. Appl. Phys. 94, 7105-7111 (2003) , “Electrically detected magnetic resonance of ion-implantation damage centers in silicon large-scale integrated circuits”, T. Umeda, Y. Mochizuki, K. Okonogi, K. HamadaWe used electrically detected magnetic resonance to study the microscopic structure of ion-implantation-induced point defects that remained in large-scale Si integrated circuits (Si LSIs). Two types of defects were detected in the source/drain (n+-type) region of... (Read more)
- 6. J. Appl. Phys. 94, 1 (2003) , “Negative bias temperature instability: Road to cross in deep submicron silicon semiconductor manufacturing”,We present an overview of negative bias temperature instability (NBTI) commonly observed in p-channel metaloxidesemiconductor field-effect transistors when stressed with negative gate voltages at elevated temperatures. We discuss the results of such stress on device and circuit... (Read more)
- 7. J. Vac. Sci. Technol. B 16, 2134-2153 (1998) , “What can electron paramagnetic resonance tell us about the Si/SiO2 system?”, P. M. Lenahan, J. F. Conley, Jr.Electron paramagnetic resonance (EPR) measurements of Si/SiO2 systems began over 30 years ago. Most EPR studies of Si/SiO2 systems have dealt with two families of defects: Pb centers and E centers. Several variants from each group have...

- 8. Jpn. J. Appl. Phys. 34, 5483-5488 (1995) , “Effects of Grown-in Hydrogen on Lifetime of Czochralski Silicon Crystals ”, Akito HaraI studied the effects of grown-in hydrogen on the lifetime of Czochralski-grown silicon crystals. It was found that grown-in hydrogen degraded the electrical properties of Czochralski-grown silicon crystals by enhancing the formation of recombination centers, which had a high thermal stability...
