Abstract
A semiconductor device includes a first memory array which includes a first memory string including a plurality of first memory cells arranged in a vertical direction. The first memory array further includes a first conductive structure operatively coupled to the first memory string that extends through the first memory array in the vertical direction. The semiconductor device further includes a second memory array including a second memory string including a plurality of second memory cells arranged in the vertical direction. The second memory array further includes a second conductive structure operatively coupled to the second memory string that extends through the second memory array in the vertical direction. The semiconductor device further includes a bowl-shaped conductive structure interposed between the first and second memory arrays, and configured to operatively couple the first conductive structure to the second conductive structure.
