Ni Schottky barrier on heavily doped phosphorous implanted 4H-SiC
Marilena Vivona, Giuseppe Greco, Monia Spera +4
The electrical behavior of Ni Schottky barrier formed onto heavily doped (ND>1019 cm-3) n-type phosphorous implanted silicon carbide (4H-SiC) was investigated, with a focus on the…
Interfacial electrical and chemical properties of deposited SiO2 layers in lateral implanted 4H-SiC MOSFETs subjected to different nitridations
Patrick Fiorenza, Corrado Bongiorno, Filippo Giannazzo +4
In this paper, SiO2 layers deposited on 4H-SiC and subjected to different post deposition annealing (PDA) in NO and N2O were studied to identify the key factors influencing the cha…
Nanoscale insights on the origin of the Power MOSFETs breakdown after extremely long high temperature reverse bias stress
P. Fiorenza, M. Alessandrino, B. Carbone +8
In this work, the origin of the dielectric breakdown of 4H-SiC power MOSFETs was studied at the nanoscale, analyzing devices that failed after extremely long (three months) of high…
Understanding the role of threading dislocations on 4H-SiC MOSFET breakdown under high temperature reverse bias stress
P. Fiorenza, M. Alessandrino, B. Carbone +7
The origin of dielectric breakdown was studied on 4H-SiC MOSFETs that failed after three months of high temperature reverse bias (HTRB) stress. A local inspection of the failed dev…
On the origin of the premature breakdown of thermal oxide on 3C-SiC probed by electrical scanning probe microscopy
P. Fiorenza, E. Schilirò, F. Giannazzo +4
The dielectric breakdown (BD) of thermal oxide (SiO2) grown on cubic silicon carbide (3C-SiC) was investigated comparing the electrical behavior of macroscopic metal-oxidesemicondu…
Identification of two trapping mechanisms responsible of the threshold voltage variation in SiO/4H-SiC MOSFETs
Patrick Fiorenza, Filippo Giannazzo, Mario Saggio +1
A non-relaxing method based on cyclic gate bias stress is used to probe the interface or near-interface traps in the SiO/4H-SiC system over the whole 4H-SiC band gap. The tempe…
