| 摘要 |
A non-volatile memory device is provided that includes a gap in one of the layers of the inter-gate dielectric. One embodiment comprises a plurality of active areas, isolation regions between the active areas, a tunnel oxide layer above the active areas, a floating gate layer above the tunnel oxide layer, a control gate layer above the floating gate layer, and an inter-gate dielectric between the control gate layer and the floating gate layer. The inter-gate dielectric, which in one embodiment includes a SiN layer, is positioned above the isolation regions with gaps in the SiN layer over the isolation regions. Processes for manufacturing are also disclosed. |
