Abstract:
According to one embodiment, a method includes forming a drain contact above a channel, each having a hollow circular cross-section thereof along a plane perpendicular to a film thickness direction, forming gate dielectric layers on sides of the drain contact and the channel, forming a source line positioned below the channel that is electrically coupled to a plurality of channels in a direction along the plane, forming gate layers on sides of the gate dielectric layers, where an inner gate layer fills a hole through a center of a center concentric circular cross-section of the gate dielectric layers along the plane, and where an outer gate layer surrounds an outside concentric circular cross-section of the gate dielectric layers along the plane, forming an electrode above the upper surface of the drain contact, and forming a fourth insulative layer on sides of the electrode along the plane.

Claim (Index 10):
The method as recited in  claim 8 , wherein forming the source line comprises:\n forming a source layer below the channel in the film thickness direction by doping the substrate with ions to form an n+doped polysilicon material, the source layer being electrically coupled to the channel; forming and patterning a second masking layer above the gate dielectric layers positioned above the drain contact and above the hole in the center of the drain contact in the film thickness direction, wherein the second masking layer has a rectangular cross-section along the plane perpendicular to the film thickness direction that is positioned above a plurality of drain contacts; and removing portions of the source layer and substrate not covered by the second masking layer in the film thickness direction to form the source line.
