SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
According to one embodiment, the first separation film separates the control electrode, the first insulating layer, the charge storage layer, the intermediate insulating layer, the floating electrode layer, and the second insulating layer in a first direction. The second separation film separates a first stacked unit in a second direction. The first stacked unit includes the charge storage layer, the intermediate insulating layer, the floating electrode layer, the second insulating layer, and the semiconductor layer. The second direction intersects the first direction. The second separation film contains silicon. |
