摘要： A predetermined species such as nitrogen is placed at an interface between a bit line junction and a dielectric layer of a control dielectric structure of a flash memory device to minimize degradation of such an interface by minimizing formation of interface defects during program or erase operations of the flash memory device. The predetermined species such as nitrogen is implanted into a bit line junction of the flash memory device. A thermal process is performed that heats up the semiconductor wafer such that the predetermined species such as nitrogen implanted within the semiconductor wafer thermally drifts to the interface between the bit line junction and the control dielectric structure during the thermal process. The predetermined species such as nitrogen at the interface minimizes formation of interface defects and thus degradation of the interface with time during the program or erase operations of the flash memory device.

摘要： An improved flash memory device having core stacks and periphery stacks which are protected by first and second thin side walls, side spacers over the side walls, and an HTO layer over the stacks, and side spacer. The flash memory device has an intermetallic dielectric layer placed over the HTO layer. A tungsten plug is placed in the intermetallic dielectric layer to provide an electrical connection to the drain of the flash memory device. The additional first and second side walls reduce current leakage between core stacks and the tungsten plug and help to protect the stacks during fabrication.

摘要： An improved flash memory device, which comprises core stacks and periphery stacks which are protected with an oxide layer, a protective layer and an insulating layer. A high energy dopant implant is used to pass the dopant through the insulating layer, the protective layer, and oxide layer into the substrate to create source and drain regions, without using a self aligned etch. The flash memory device has an intermetallic dielectric layer placed over the core stacks and the periphery stacks. A tungsten plug is placed in the intermetallic dielectric layer to provide an electrical connection to the drain of the flash memory device. The use of a high energy dopant implant to pass through dopant through the insulating layer, the protective layer, and the oxide layer into the substrate without the use of a self aligned source etch, reduces damage to the core stacks and periphery stacks caused by various etches during the production of the flash memory device and provides insulation to reduce unwanted current leakage between the tungsten plug and the stacks.

摘要： An improved method of making a flash memory cell including a substrate having a floating gate of a first thickness includes depositing an insulator on the substrate and over the floating gate. The insulator is preferably a high quality oxide. A portion of the insulator not covering the floating gate has a second thickness which is greater than the first thickness of the floating gate. The method further includes polishing the insulator until the second thickness is substantially equal to the first thickness. Polishing results in a planar floating gate and insulator layer. The method further includes sequentially depositing a dielectric layer and a control gate layer on the planar floating gate and insulator layer and then etching these layers to complete the stacked gate structure of the memory cell.
