11. Reliability Monitoring For Highly Leaky Devices
Published: 5/31/2013
Authors: Jason T Ryan, Jason P Campbell, Kin P Cheung, John S Suehle, Richard Southwick, Anthony Oates
Abstract: We demonstrate a new charge pumping (CP) methodology, frequency modulated CP (FMCP), that robustly treats metrology challenges associated with high gate leakage current. By moving to an AC coupled measurement, we are able to easily resolve small CP s ...

12. Frequency-Modulated Charge Pumping: Defect Measurements with High Gate Leakage
Published: 2/28/2013
Authors: Jason T Ryan, Richard G. Southwick, Jason P Campbell, Kin P Cheung, John S Suehle, Anthony Oates
Abstract: Charge pumping is one of the most relied upon techniques used to quantify interface defects in metal-oxide-semiconductor devices. However, conventional charge pumping is easily hindered by excessive gate leakage currents which render the technique un ...

13. Frequency Dependent Charge Pumping -- A Defect Depth Profiling Tool?
Published: 1/31/2013
Authors: Jason T Ryan, Richard G. Southwick, Jason P Campbell, Kin P Cheung, John S Suehle
Abstract: We investigate the validity of using frequency-dependent charge pumping (FD-CP) to determine bulk defect depth distributions. Using simple physical arguments we conclude that: (1) the effective tunneling length to a bulk defect can be very different ...

14. SERIES RESISTANCE: A MONITOR FOR HOT CARRIER STRESS
Published: 1/31/2013
Authors: Jason P Campbell, Serghei Drozdov, Kin P Cheung, Richard G. Southwick, Jason T Ryan, John S Suehle, Anthony Oates
Abstract: In this work, we examine a series resistance extraction technique which yields accurate values from single nano-scale devices. The series resistance values, derived from this extraction technique, are shown to be sensitive to hot carrier degradation ...

15. Observation of Interface/Near Interface Defects in 4H SiC MOSFETs With a New Electrically Detected Magnetic Resonance Technique
Published: 1/1/2013
Authors: Jason T Ryan, Brad Bittel, Pat Lenahan, Jody Fronheiser, Aivars Lelis
Abstract: We study 4H SiC MOSFETs with a new electrically detected magnetic resonance technique (EDMR) we call spin dependent charge pumping (SDCP). Our SDCP results demonstrate a tremendous improvement in sensitivity over other EDMR techniques. Addition ...

16. On the Contribution of Bulk Defects on Charge Pumping Current
Published: 10/1/2012
Authors: Jason T Ryan, Richard G. Southwick, Jason P Campbell, Kin P Cheung, John S Suehle
Abstract: Frequency dependent charge pumping (FD-CP) has emerged as a popular technique for studying the spatial and energetic distribution of defect centers in advanced high-k gate stacks. However, conflicting interpretations of the charge pumping frequency - ...

17. Physical Model for Random Telegraph Noise Amplitudes and Implications
Published: 6/12/2012
Authors: Richard G. Southwick, Kin P Cheung, Jason P Campbell, Serghei Drozdov, Jason T Ryan, John S Suehle, Anthony Oates
Abstract: Random Telegraph Noise (RTN) has been shown to surpass random dopant fluctuations as a cause for decananometer device variability, through the measurement of a large number of ultra-scaled devices [1]. The most worrisome aspect of RTN is the tail of ...

18. Channel Length-Dependent Series Resistance?
Published: 6/10/2012
Authors: Jason P Campbell, Kin P Cheung, Serghei Drozdov, Richard G. Southwick, Jason T Ryan, Tony Oates, John S Suehle
Abstract: A recently developed series resistance (RSD) extraction procedure from a single nanoscale device is shown to be highly robust. Despite these virtues, the technique unexpectedly results in a channel length-dependent RSD which is observed across a wide ...

19. Spectroscopic Charge Pumping in the Presence of High Densities of Bulk Dielectric Traps
Published: 5/31/2012
Authors: Jason T Ryan, Richard G. Southwick, Jason P Campbell, Kin P Cheung, Chadwin Young
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=911208

20. Experimentally Based Methodology for Charge Pumping Bulk Defect Trapping Correction
Published: 12/15/2011
Authors: Jason T Ryan, Richard G. Southwick, Jason P Campbell, Kin P Cheung, Chadwin Young, John S Suehle
Abstract: We develop a simple experimental approach to remove bulk trap contributions from charge pumping data collected on devices which suffer from large amounts of bulk dielectric electron trapping. The approach is more desirable and easier to implemen ...
