    摘要: A method of programming a memory cell with a substrate that includes a first region and a second region with a channel therebetween and a gate above the channel, and a charge trapping region that contains a first amount of charge. The method includes applying a constant first voltage across the gate, applying a second constant voltage across the first region and applying a third voltage that is constant and negative to the substrate so that the effect of spillover electrons is substantially reduced when compared with when the third constant voltage is absent.

    摘要: The present invention provides a method and system for the formation of semiconductor devices which reduces band-to-band tunneling current and short-channel effects. The method and system includes implanting first low-dose arsenic into an area in the substrate, thermally diffusing the first low-dose arsenic through a portion of the substrate, implanting a second higher-dose arsenic into the area in the substrate, and diffusing the second higher-dose arsenic into the area in the substrate. Under the present invention, the combination of the first and second arsenic implants has a graded lateral profile which reduces band-to-band tunneling current and short-channel effects. The method also improves the reliability and performance of the semiconductor devices.
