Abstract:
A 3D memory structure including a modified floating gate and dielectric layer geometry is described. In embodiments, a memory cell includes a channel region and a floating gate where a length of the floating gate along a direction of the channel region is substantially longer than a length of the floating gate along an orthogonal direction along the channel region. A control gate adjacent to the floating gate extends at least as long as the control gate along the direction of the channel region and includes a tapered edge extending away from the channel region towards the control gate. In embodiments, a dielectric layer between the control gate and the floating gate may follow the tapered edge along the floating gate and form a discrete region proximate to the floating gate to at least partially insulate the floating gate from an adjacent memory cell. Other embodiments are disclosed and claimed.

Claim (Index 16):
A method to manufacture a memory device, comprising:\n forming, in a substrate, a channel region; forming a plurality of control gates adjacent to the channel region; forming, adjacent to the plurality of control gates, a corresponding plurality of floating gates, each floating gate to extend as long as a corresponding control gate along a direction of the channel region; and forming a dielectric layer, disposed between the plurality of control gates and the plurality of floating gates, wherein the dielectric layer is to follow a tapered edge along one or more of the floating gates and to form a discrete region proximate to the one or more floating gates to assist in insulating a memory cell including the one or more floating gates and corresponding control gates, and wherein a length of the floating gate along a direction of the channel region is substantially longer than a length of the floating gate along an orthogonal direction of the channel region.
