Claim 16:
17. A device, comprising:
a vertically oriented pillar comprising:
an unetched composite oxide semiconductor material comprising:
a first oxide semiconductor material; and
a second oxide semiconductor material neighboring the first oxide semiconductor material and having a different material composition than the first oxide semiconductor material;

wherein a lower portion of the unetched composite oxide semiconductor material has a greater width than an upper portion thereof in a first lateral direction; and
wherein the upper portion of the unetched composite oxide semiconductor material has a greater width than the lower portion thereof in a second lateral direction;

a gate dielectric material on sidewalls of the vertically oriented pillar; and
a gate electrode on at least a portion of the gate dielectric material.
