Abstract

When a thin channel semiconductor layer formed on a side wall of a stacked film in which insulating films and gate electrodes are alternately stacked together is removed on the stacked film, a contact resistance between a vertical transistor including the channel semiconductor layer and the gate electrode, and a bit line formed on the stacked film is prevented from rising. As its means, a conductive layer electrically connected to the channel semiconductor layer is disposed immediately above the stacked film.
