Abstract:
A split-gate flash memory cell (cell) that can be formed by a method including self-aligned patterning for the select gates includes a semiconductor surface. A first control gate (CG) on a first floating gate (FG) and a second CG on a second FG are on the semiconductor surface. A common source/drain is between the first and second FG. A first select gate and a second select gate are on a select gate dielectric layer that is between a first BL source/drain in the semiconductor surface and the first FG and between a second BL source/drain and the second FG, respectively. The first select gate and the second select gate are spacer-shaped.

Claim (Index 16):
A split-gate memory cell, comprising:\n a semiconductor substrate; a first dielectric layer disposed on the semiconductor substrate; a first gate stack disposed on the first dielectric layer and including a first control gate arranged over a first floating gate; a second gate stack disposed on the first dielectric layer and including a second control gate arranged over a second floating gate; a common source/drain disposed in the semiconductor substrate and extending from the first floating gate to the second floating gate; a first spacer-shaped select gate disposed on the first dielectric layer and arranged between the first floating gate and a first bitline source/drain disposed in the semiconductor substrate; and a second spacer-shaped select gate disposed on the first dielectric layer and arranged between the second floating gate and a second bitline source/drain disposed in the semiconductor substrate.
