A self-aligned contact ETOXtrade flash memory process with W-gate capable of MLC operation is presented for the first time. Several key process elements were successfully integrated to achieve functional test structures. Significant cell area reduction can be realized using the SAC architecture by aggressive cell height scaling and thus this approach(More)
We performed studies of electron emission from ultrananocrystalline diamond ~UNCD!-coated, ungated silicon field emitters as a function of in situ exposure to various gases during current versus voltage and current versus time measurements. The emitter arrays were fabricated by a subtractive tip fabrication process and coated with UNCD films using microwave(More)
Wide band-gap materials show promise for applications in coating of field emission tips. Recently nanocrystalline hexagonal GaN crystallites as small as 12 nm average diameter have been formed using reactive laser ablation of gallium metal in nitrogenating ambient @T. J. Goodwin et al., Appl. Phys. Lett. 70, 3122 ~1997!#. In this article we investigated the(More)
Wide band gap materials show promise for applications in coating of field emission tips. Recently nanocrystalline hexagonal GaN crystallites as small as 5 nm average diameter have been formed using reactive laser ablation of gallium metal in a nitrogenating ambient. In this paper we have investigated the performance of ungated emitter. Silicon tip arrays(More)
