Abstract:
A method for fabricating a semiconductor device includes forming a plurality of active regions, each having a first sidewall and a second sidewall, by etching a semiconductor substrate, forming an insulation layer on the first sidewall and the second sidewall, forming an etch stop layer filling a portion of each gap between the active regions, forming a recess exposing the insulation layer formed on any one sidewall from among the first sidewall and the second sidewall, and forming a side contact exposing a portion of any one sidewall from among the first sidewall and the second sidewall by selectively removing a portion of the insulation layer.
