Abstract
A cell array region and a peripheral transistor region are provided. In the cell array region, a plurality of memory cell transistors are formed, and element regions of the memory cell transistors are isolated by an embedded isolation region. In the peripheral transistor region, a plurality of peripheral circuit transistors are formed, and element regions of the peripheral circuit transistors are isolated by an embedded isolation region. Isolation end portions of the gate electrode of each peripheral circuit transistor do not fall in grooves of the embedded isolation region but is positioned to be horizontal to the center part of the gate electrode.
