Abstract:
1. A method of forming non-volatile storage, comprising: forming over a plurality of global bit lines that are elongated in a first direction a plurality of layer stack lines that are elongated in a second direction, each layer stack line of the plurality having two vertical sidewalls and including one or more silicon layers for the body of a plurality of vertical thin film transistor (TFT) select devices; forming a gate dielectric layer after forming the plurality of layer stack lines, the gate dielectric layer extending along the two vertical sidewalls of each layer stack line and over the plurality of global bit lines continuously from one vertical sidewall of each layer stack line to an adjacent vertical sidewall of an adjacent layer stack line in the first direction; forming a gate layer after forming the gate dielectric layer; and etching back the gate layer to form a first gate and a second gate for each layer stack line of the plurality, the first gate and the second gate are separated from the corresponding layer stack line by the gate dielectric layer.
