Abstract:
1. A semiconductor device manufacturing method comprising: forming a plurality of gate electrodes on a semiconductor substrate; forming an etching prevention film over the surface of adjacent gate electrodes and on the semiconductor substrate between the adjacent gate electrodes; forming an organic insulation film having heat-resistance on the etching prevention film; removing the organic insulation film above the gate electrodes in such a manner that the organic insulation film remains between the gate electrodes; forming an interlayer insulation film on a laminate section obtained by the organic insulation film removing step; for forming a contact hole by removing the interlayer insulation film on the remaining organic insulation film with a width wider than the distance between the gate electrodes; and exposing the semiconductor substrate between the gate electrodes by removing the organic insulation film and the etching prevention film remaining inside the contact hole.
