    摘要: A dual charge storage node memory device and methods for its fabrication are provided. In one embodiment a dielectric plug is formed comprising a first portion recessed into a semiconductor substrate and a second portion extending above the substrate. A layer of semiconductor material is formed overlying the second portion. A first layered structure is formed overlying a first side of the second portion of the dielectric plug, and a second layered structure is formed overlying a second side, each of the layered structures overlying the layer of semiconductor material and comprising a charge storage layer between first and second dielectric layers. Ions are implanted into the substrate to form a first bit line and second bit line, and a layer of conductive material is deposited and patterned to form a control gate overlying the dielectric plug and the first and second layered structures.

    摘要: A method for performing shallow trench isolation during semiconductor fabrication that improves trench corner rounding is disclosed. The method includes etching trenches into a silicon substrate between active regions, and performing a double liner oxidation process on the trenches. The method further includes performing a double sacrificial oxidation process on the active regions, wherein corners of the trenches are substantially rounded by the four oxidation processes.
