Time Dependent Dielectric Breakdown in 4H-SiC power MOSFETs under positive and negative gate-bias and gate-current stresses at 200°C
P. Fiorenza, F. Cordiano, S. M. Alessandrino +6
The gate oxide lifetime in 4H-SiC power MOSFETs is typically assessed at fixed and constant gate bias stress, monitoring the time-dependent dielectric breakdown (TDDB).
Complementary two dimensional carrier profiles of 4H-SiC MOSFETs by Scanning Spreading Resistance Microscopy and Scanning Capacitance Microscopy
Patrick Fiorenza, Marco Zignale, Edoardo. Zanetti +6
This paper reports the results presented in an invited poster during the International Conference on Silicon Carbide and Related Materials (ICSCRM) 2023 held in Sorrento, Italy. Th…
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…
