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 16):
An apparatus, comprising:\n a drain contact positioned above a channel in a film thickness direction, wherein the drain contact and the channel have a circular cross-sectional hole in a center of a circular cross-section thereof along a plane perpendicular to the film thickness direction; gate dielectric layers positioned on sides of the drain contact and on sides of the channel, the gate dielectric layers having concentric circular cross-sections along the plane perpendicular to the film thickness direction, wherein the circular cross-section of the drain contact has one circular cross-sectional portion of the gate dielectric layers in direct contact on either side thereof; a source line positioned below the channel in the film thickness direction, wherein the source line is electrically coupled to the channel and is configured to electrically couple to a plurality of additional channels in a direction along the plane perpendicular to the film thickness direction; gate layers positioned on sides of the gate dielectric layers, the gate layers having a lower surface at a level above an upper surface of the source line and a thickness coincident with a lower surface of the drain contact in the film thickness direction, wherein 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 perpendicular to the film thickness direction, and wherein an outer gate layer surrounds an outside concentric circular cross-section of the gate dielectric layers along the plane perpendicular to the film thickness direction; an electrode positioned above the upper surface of the drain contact; and a fourth insulative layer positioned on sides of the gate layers, sides of the gate dielectric layers, and sides of the electrode along the plane perpendicular to the film thickness direction.
