Abstract:
Methods for forming a string of memory cells, apparatuses having a string of memory cells, and systems are disclosed. One such method for forming a string of memory cells forms a source material over a substrate. A capping material may be formed over the source material. A select gate material may be formed over the capping material. A plurality of charge storage structures may be formed over the select gate material in a plurality of alternating levels of control gate and insulator materials. A first opening may be formed through the plurality of alternating levels of control gate and insulator materials, the select gate material, and the capping material. A channel material may be formed along the sidewall of the first opening. The channel material has a thickness that is less than a width of the first opening, such that a second opening is formed by the semiconductor channel material.

Claim (Index 2):
A method for forming a string of memory cells, comprising:\n forming a source select gate material over a source; forming multiple levels of control gate material alternating with multiple dielectric levels, and extending over the source select gate material and over the source; forming a recess extending through the control gate material levels and the dielectric levels; forming respective charge storage structures in the control gate material levels; forming a semiconductor pillar extending through the control gate material levels and the dielectric levels, and through the source gate material, the semiconductor pillar extending adjacent the multiple charge storage structures adjacent the first opening; removing the semiconductor pillar to leave a first opening defined by sidewalls, the first opening extending through the alternating control gate material and dielectric levels, the first opening extending adjacent multiple charge storage structures; forming a vertical semiconductor material along the sidewalls defining the first opening, the vertical semiconductor material extending to the source, wherein the charge storage structures are separated from the vertical semiconductor material by a dielectric, the vertical semiconductor material defining a second opening within the vertical semiconductor material.
