Abstract
A semiconductor device is provided that can include a stack formed of word line layers and insulating layers that are alternatingly stacked over a substrate. A first staircase of a first block can be formed in the stack and extend between first array regions of the first block. A second staircase of a second block can be formed in the stack and extend between second array regions of the second block. The semiconductor device further can have a connection region that is formed in the stack between the first staircase and second staircase.
