Abstract
A method, for fabricating a semiconductor device including a memory region and a logic circuit region including a periphery circuit, includes: forming sidewall-like control gates on both side surfaces of a first conductive layer at least in a memory region with an ONO film interposed therebetween, respectively; patterning a first conductive layer in a logic circuit region and thereby forming a gate electrode of a MOS transistor; forming a second insulating layer above the control gates; applying anisotropic etching to the second insulating layer, and thereby at least partially exposing the control gates; and on the exposed surfaces of the control gates, forming a silicide layer.
