Device Simulation of Density of Interface States of Temperature Dependent Carrier Concentration in 4H-SiC MOSFETs
(2014-07-29)
Interface traps play an important role in the SiO2/4H-SiC interface. They are crucial
issues for the current and trans-conductance in 4H-SiC MOSFET devices. In this thesis,
we present a temperature and bias dependent ...
Diagnostic Test Generation for Path Delay Faults in a Scan Circuit
(2015-07-24)
With the increase of density, speed and test time of large VLSI circuits, man-
ufacturers are eager to nd e cient ways to bring up yields. Often, VLSI testing
