Journal of the Microelectronic Engineering Conference
Ferroelectric (FE) materials exhibit spontaneous polarization making them particularly attractive for non-volatile memory and logic applications. Recently, doped hafnium oxide has shown to be ferroelectric in nature expanding its applications to these areas of interest. Ferroelectricity has been reported in atomic layer deposition (ALD) of HfO2 with Al, Y, or Si dopants. Previous work at RIT demonstrated functional ferroelectric field effect transistors (FeFETs) using silicon doped HfO2 (Si:HfO2) as the gate dielectric.
The new addition of a Savannah ALD system at RIT has made deposition of doped HfO2 films possible. Recipes have been developed for deposition of aluminum doped HfO2 …
Capacitance-Voltage Analysis Of High-? Dielectric On Strained Silicon, Mike Latham
Capacitance-Voltage Analysis Of High-? Dielectric On Strained Silicon, Mike Latham
Journal of the Microelectronic Engineering Conference
Device characteristics are reported on Hf02 gate dielectrics deposited by atomic layer deposition (ALD), and jet vapor deposition (JVD) on strained-Si and bulk Si samples. Capacitance-Voltage (CV) analysis of samples shows comparable interface charge levels between strained-Si and bulk Si samples. A flat band shift of -0.5V was noted between the strained-Si and bulk Si for the JVD samples.
