Title:
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD FOR SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/045054
Kind Code:
A1
Abstract:
A semiconductor device comprises: first pillar-shaped silicon layers (129, 131, 132, and 134); first gate dielectric layers (162) formed around the first pillar-shaped silicon layers; gate electrodes (168a and 170a), comprising metal, which are formed around the first gate dielectric layers; gate wires (168b and 170b), comprising metal, which are connected to the gate electrodes; second gate dielectric layers (173) formed around the upper portions of the first pillar-shaped silicon layers (129, 131, 132, and 134); first contacts (179a, 179b, 181a, and 181b), comprising a first metal material, which are formed around the second gate dielectric layers; second contacts (183a, 183b, 185a, and 185b), comprising a second metal material, which connect the tops of the first contacts with the tops of the first pillar-shaped silicon layers; second diffusion layers (143a and 143b) formed at the bottom of the first pillar-shaped silicon layers; and storage elements (201a, 201b, 202a, and 202b) formed above the second contacts, with variable resistance.
