ABSTRACTMOS memory devices containing semiconductor nanocrystals have drawn considerable attention recently, due to their advantages when compared to the conventional memories. Only little work has been done on memory devices containing metal nanoparticles.We describe the fabrication of a novel MOS device with embedded Pt nanoparticles in the HfO2 / SiO2 interface of a MOS device. Using as control oxide, a high-k dielectric, our device has a great degree of scalability. The fabricated nanoparticles are very small (about 5 nm) and have high density. High frequency C-V measurements demonstrate that this device operates as a memory device.

ABSTRACTA design-of-experiments methodology was implemented to assess the commercial equipment viability to fabricate the high-K dielectrics Ta2O5, TiO2 and BST (70/30 and 50/50 compositions) for use as gate dielectrics. The high-K dielectrics were annealed in 100% or 10% O2 for different times and temperatures in conjunction with a previously prepared NH3 nitrided or 14N implanted silicon surface. Five metal electrode configurations—Ta, TaN, W, WN and TiN—were concurrently examined. Three additional silicon surface configurations were explored in conjunction with a more in-depth set of time and temperature anneals for Ta2O5. Electrical characterization of capacitors fabricated with the above high-K gate dielectrics, as well as SIMS and TEM analysis, indicate that the post high-K deposition annealing temperature was the most significant variable impacting the leakage current density, although there was minimal influence on the capacitance. Further studies are required, however, to clarify the physical mechanisms underlying the electrical data presented.
