Abstract
A semiconductor device includes a stack including first electrode films stacked in a first direction. First and second isolating portions isolate the first electrode films. Third and fourth isolating portions isolate only one or more of the first electrode films in an upper portion of the first electrode films in the stack in a third direction, and are arranged in the third direction between the first and second isolating portions. The column portions include first and second column portions between the first and third isolating portions. The column portions include third and fourth column portions between the third and fourth isolating portions. The second column portion is adjacent to the first column portion. The fourth column portion is adjacent to the third column portion. A first interval between the first and second column portions is different from a second interval between the third and fourth column portions.
