Abstract
A semiconductor device includes: a semiconductor region; a plurality of stacked structures each of which is disposed on the semiconductor region and has a tunnel insulating film, a charge storage layer, an upper insulating layer, and a control electrode stacked sequentially; an element isolation insulating layer disposed on side faces of the plurality of stacked structures; and a source-drain region disposed on the semiconductor region and among the plurality of stacked structures. The element isolation insulating layer includes at least one of SiO, SiN, and SiON, the upper insulating layer is an oxide containing at least one metal M selected from the group consisting of a rare earth metal, Y, Zr, and Hf, and Si, and respective lengths L, L, and Lof the charge storage layer, the upper insulating layer, and the control electrode in a channel length direction satisfy the relation 'L<Land L<L'.
