摘要： A method of fabricating an improved flash memory device having 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 between the tungsten plug and the stacks.

摘要： A method of preventing UV charging of flash NVROM cells during fabrication and a device thereby formed. During device fabrication, a UV blocking layer is deposited over the floating gates. The UV blocking layer substantially blocks UV from entering the gate regions so as to prevent electron mobility sufficient to render the cells unprogrammable or unerasable. The reduced electron migration during processing of the NVROM leads to increased yield and reliability of the devices.

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.
