    Abstract: An interface between a bottom oxide film and a silicon nitride film in a neighborhood of a bottom part of a select gate is located at a position as high as or higher than that of an interface between a silicon substrate (p-type well) and a gate insulating film (d?0) Further, the gate insulating film and the bottom oxide film are successively and smoothly jointed in the neighborhood of the bottom part of the select gate. By this configuration, localization in a distribution of electrons injected into the silicon nitride film in the writing is mitigated and electrons to be left unerased by hot-hole erasing are reduced. Therefore, not only the increase ratio of the electrons left unerased in the writing can be reduced, but also the problem in which the threshold voltage does not decrease to the predetermined voltage in the deletion can be suppressed.

    Abstract: Methods of forming a semiconductor structure having FinFET's and planar devices, such as MOSFET's, on a common substrate by a damascene approach, and semiconductor structures formed by the methods. A semiconductor fin of the FinFET is formed on a substrate with damascene processing in which the fin growth may be interrupted to implant ions that are subsequently transformed into a region that electrically isolates the fin from the substrate. The isolation region is self-aligned with the fin because the mask used to form the damascene-body fin also serves as an implantation mask for the implanted ions. The fin may be supported by the patterned layer during processing that forms the FinFET and, more specifically, the gate of the FinFET. The electrical isolation surrounding the FinFET may also be supplied by a self-aligned process that recesses the substrate about the FinFET and at least partially fills the recess with a dielectric material.

    Abstract: In a MOS transistor having a structure in which a source and a drain are raised on a substrate by using a selective epitaxial growth technique, a bulk resistance can be reduced while an impurity concentration of a silicon layer is reduced in the selective epitaxial growth. A metal oxide semiconductor transistor includes a gate having a sidewall formed on a silicon substrate, a silicon layer formed on the silicon substrate by selective epitaxial growth, and an inclination portion inclined downward in a direction opposite to the gate on at least a portion of a cross-section including the silicon layer and the gate.

    Abstract: A gate of a transistor includes a gate oxide layer formed on a semiconductor device, a first conductive layer pattern including polysilicon doped with boron and formed on the gate oxide layer, a diffusion preventing layer pattern including amorphous silicon formed by a chemical vapor deposition process using a reaction gas having trisilane (Si3H8) and formed on the first conductive layer pattern, and a second conductive layer pattern including metal silicide and formed on the diffusion preventing layer pattern. Since a gate of PMOS transistor includes a diffusion preventing layer having an excellent surface morphology, diffusion of impurities is sufficiently prevented. Thus, the threshold voltage of PMOS transistor may be reduced and threshold voltage distribution may be improved.
