Abstract:
An EEPROM memory cell includes a dual-gate MOS transistor in which the two gates are separated by an insulation layer. The insulation layer includes a first portion and a second portion having lower insulation properties than the first one. The second portion is located at least partially above a channel region of the transistor.

Claim (Index 9):
A method, comprising:\n forming source and drain regions of a first conductivity type over a substrate; forming a channel region of a second conductivity type over the substrate and extending between the source and drain regions; forming in the source and channel regions a first doped region extending between the source and channel regions, the first doped region having the first conductivity type and including a portion extending the channel region; forming in the source and channel regions a second doped region extending between the drain and channel regions, the second doped region having the first conductivity type and including a portion extending in the channel region; forming a first insulating layer on the channel region; forming a floating gate on the first insulating layer; forming a second insulating layer on the floating gate; forming an opening in the second insulating layer, the opening at least partially overlapping the portion of the first doped region extending in the channel region; forming a third insulating layer in the opening, the third insulating layer being less insulating than the second insulating layer; and forming a control gate on the second and the third insulating layers.
