Claim Text:
1. An apparatus comprising: a vertical string of memory cells formed at least partially in a stack of materials comprising wherein a monolithic channel material of the vertical string of memory cells is adjacent to the tunnel dielectric material and extends adjacent to the plurality of alternating levels of control gate material and insulator material, the channel material having a thickness that is less than a width of a first opening through the alternating levels of control gate material and insulator material in which channel material is formed, such that a second opening is defined by the channel material and the channel material is monolithic with regard to having a single structure covering a sidewall and a bottom of the first opening; a conductive plug formed in the second opening to connect the channel material; and a metal source coupled between the channel material and a substrate, wherein an oxide is formed between the metal source and the substrate.
