Abstract:
1. A method for fabricating a semiconductor device, comprising: forming a plurality of active regions, each having a first sidewall and a second sidewall, by etching a semiconductor substrate, wherein the active regions are extended in one direction and isolated from each other by a line-type trench; 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; 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, wherein the side contact is an opening in the shape of a line, which extends on the first sidewall or the second sidewall of each of the active regions; wherein the exposing of the insulation layer comprises:
