Abstract:
A first dielectric layer is formed over a substrate. A single layer first conductive layer that acts as a floating gate is formed over the first dielectric layer. A trough is formed in the first conductive layer to increase the capacitive coupling of the floating gate with a control gate. An intergate dielectric layer is formed over the floating gate layer. A second conductive layer is formed over the second dielectric layer to act as a control gate.
