Patent ID: 8710583

Claim:
A recessed access device, comprising: semiconductor material having an elevationally outermost surface and having at least one trench therein; a gate dielectric over a surface of the at least one trench; a first gate material within the at least one trench over at least a portion of the gate dielectric in a bottom portion of the at least one trench, the first gate material having a first work function, the first gate material being formed to be half circle-shaped in a cross section transverse the at least one trench and having a planar elevationally outermost surface within the at least one trench in the cross section that is elevationallv inward of the elevationally outermost surface of the semiconductor material, all of the first gate material being received entirely within the at least one trench; and a second gate material overlying at least a portion of the first gate material, the second gate material having a second work function and at least partially disposed in the at least one trench, the first work function being greater than the second work function.
