碩士 === 逢甲大學 === 電機工程研究所 === 84 === In this thesis, a novel study of BF2+ - implanted gate pMOS
devices by using the Inductive-Coupling-Nitrogen-Plasma
(ICNP)treatment within the stacked Amorphous / Polysilicon (SAP)
gate structures is investigatedon the suppression of boron
penetration effect for the submicron CMOS applications.From the
experimental measurements of flatband voltage shifts and charge
to breakdown values and the breakdown field and high-frequency
capacitance-voltage curves,results show about the effect of the
boron diffusion through the thin gate oxide can be significantly
suppressed by using this novel method.The suppression of
penetration effects with the combination of the ICNP treatment
and the SAP gate structures are believed to due to boron
impurities are caught by introducing the nitrogen atoms from the
ICNP treatment effect and the dopant segregation at the
amorphous / polysilicon interface and longer path for dopant
diffussion to the gate / oxide interface from the SAP gate
structures effect.By using the ICNP/ SAP gate structures instead
of the polysilicon gate structures on must be concerned that the
α-Si thickness needs to over 30nm for preventing the damage
from the nitrogen plasma. Under stacking the amorphous-Si
thickness of 30nm, we can suppress the boron penetration effect
more effectively for the application of next devices.
