Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus, comprising:
a first vertical transistor;
a second vertical transistor adjacent to the first vertical transistor, each of the first vertical transistor and the second vertical transistor comprising:
a channel region comprising:
an upper region having a first width; and
a lower region below the upper region and having a second width smaller than the first width, and wherein the upper region defines at least one overhang portion extending laterally beyond the lower region; and
gate electrodes each having a first portion vertically beneath the at least one overhang portion of the upper region of the channel region, and a second portion extending past the at least one overhang portion of the upper region of the channel region;

a gate dielectric material adjacent to the gate electrodes;
a conductive contact underlying the gate electrodes; and
an insulative structure directly intervening between a gate electrode of the first vertical transistor and a gate electrode of the second vertical transistor, an insulative material of the insulative structure directly intervening between an upper region of a channel region of the first vertical transistor and an upper region of a channel region of the second vertical transistor, and the insulative material of the insulative structure directly vertically intervening between the gate dielectric material and the conductive contact in regions underlying the gate electrodes.
