- 1. J. Appl. Phys. 104, 014106 (2008) , “Analysis of electrically biased paramagnetic defect centers in HfO2 and HfxSi1−xO2 / (100)Si interfaces”, P. T. Chen, B. B. Triplett, J. J. Chambers, L. Colombo, P. C. McIntyre, and Y. NishiThis study reports on the first experimental observations of electrically biased paramagnetic defects at 800 °C N2 annealed HfxSi1−xO2 (x=0.4, and 0.6)/(100)Si and HfO2/(100)Si interfaces in metal oxide silicon...

- 2. Appl. Phys. Lett. 89, 142909 (2006) , “Fluorine passivation in poly-Si/TaN/HfO2 through ion implantation”, M. H. Zhang, F. Zhu, T. Lee, H. S. Kim, I. J. Ok, G. Thareja, L. Yu, and Jack C. LeeFluorine (F) passivation in poly-Si/TaN/HfO2/p-Si gate stacks through gate ion implantation has been studied. It has been found that when the TaN thickness was less than 15 nm, the mobility and subthreshold swing improved significantly in HfO2 n-channel... (Read more)
- 3. Appl. Phys. Lett. 89, 092902 (2006) , “Charge trapping in nitrided HfSiO gate dielectric layers”, G. Vellianitis, Z. M. Rittersma, and J. PétryThe effects of HfSiO nitridation on charge trapping and long-term dielectric reliability are investigated. A comparison between decoupled plasma nitridation, annealing in NH3, and no nitridation is made. It was found that thinner HfSiO layers show less trapped charge. Decoupled plasma... (Read more)
- 4. J. Appl. Phys. 100, 064501 (2006) , “Introduction of defects into HfO2 gate dielectrics by metal-gate deposition studied using x-ray photoelectron spectroscopy and positron annihilation”, A. Uedono, T. Naito, T. Otsuka, K. Shiraishi, K. Yamabe, S. Miyazaki, H. Watanabe, N. Umezawa, T. Chikyow, Y. Akasaka, S. Kamiyama, Y. Nara, and K. YamadaThe impact of TiN deposition on thin HfO2 films formed on Si substrates was studied using x-ray photoelectron spectroscopy and a monoenergetic positron beam. For the predeposition sample, the positrons implanted into Si were found to diffuse toward the HfO2/Si interface under... (Read more)
- 5. Phys. Rev. Lett. 92, 087601 (2004) , “Hydrogen-Release Mechanisms in the Breakdown of Thin SiO2 Films”, J. Suñé and E. Y. WuThe mechanism of hydrogen release from the anode Si/SiO2 interface that triggers defect generation and finally the dielectric breakdown of the oxide in metal-oxide-semiconductor structures is investigated. Extensive experimental charge-to-breakdown statistics are used to derive the defect... (Read more)
- 6. Appl. Phys. Lett. 81, 1128-1130 (2002) , “Electron spin resonance study of interface defects in atomic layer deposited hafnium oxide on Si”, A. Y. Kang, P. M. Lenahan, J. F. Conley Jr., R. SolankiWe report electron spin resonance (ESR) observation of interface defects at the HfO2/(111)Si boundary for HfO2 films deposited via atomic layer chemical vapor deposition using Hf(NO3)4 as a precursor. We observe several signals, dominated by one due to a... (Read more)
- 7. Appl. Phys. Lett. 80, 1261-1263 (2002) , “Hole trapping in ultrathin Al2O3 and ZrO2 insulators on silicon”, V. V. Afanas'ev and A. StesmansOptical injection of electron-hole pairs in 35 nm thick layers of SiO2, Al2O3, ZrO2 and their stacks on (100)Si is found to result in positive oxide charging, suggesting trapping of holes. In thin layers of the high-permittivity metal oxides... (Read more)
- 8. Thin Solid Films 395, 266-269 (2001) , “Charge-trapping defects in Cat-CVD silicon nitride films”, T. Umeda, Y. Mochizuki, Y. Miyoshi and Y. NashimotoWe show that Cat-CVD silicon nitride films contain more than 1019 cm−3 nitrogen-bonded Si dangling bonds, similarly to the case for conventional CVD films. However, the charge-trapping behavior of the Cat-CVD films is found to be quite different, in spite of the same origin for the dominant... (Read more)

- 10. 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...

DiMariaHot electrons in the gate dielectric (SiO2) of field effect transistors create defects at the Si/SiO2 interface. Using electrically detected magnetic resonance, we have identified a major component of these interface defects as the well-known Pb0 center. We... (Read more)
