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 25):
A method for forming a string of memory cells, the method comprising:\n forming respective charge storage structures in multiple levels of control gate material, the multiple levels of control gate material alternating with multiple levels of dielectric material; forming a first opening extending through the multiple alternating levels of control gate and dielectric materials and extending to a source; forming a monolithic semiconductor liner along a sidewall of the first opening, the monolithic semiconductor liner forming an electrical connection to the source, the monolithic semiconductor liner extending adjacent to the charge storage structures, wherein the multiple charge storage structures are separated from the monolithic semiconductor liner by a tunnel dielectric, the monolithic semiconductor liner having a thickness that is less than a width of the first opening such that a second opening is formed by the liner; forming an insulator material within at least a portion of the second opening, wherein forming the insulator material comprises,\n forming an oxide within the second opening and over the drain select gate material; and \n removing the oxide formed over the drain select gate material, and forming a recess in the oxide within the second opening; and \n forming a conductive plug over the insulator material such that the plug connects to a top portion of the monolithic semiconductor liner.
