IPC: H01L21/768
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent a connection hole for connecting an electrode and a wiring from deviating in a method for manufacturing a semiconductor device with a multilayered wiring. SOLUTION: When an inter-layer insulation film 14 is deposited on a semiconductor substrate 11 where a lower layer wiring 13 is formed by the high-density plasma CVD method, a protruding part 14a whose section is in a triangular shape where a bottom side has nearly the same width dimension as that of the lower layer wiring 13 is formed at the upper portion of the lower layer wiring 13 in the inter-layer insulation film 14. Then, a silicon nitride film 15 is deposited on the inter-layer insulation film 14 and the top of the protruding part 14a is polished and one portion of the silicon nitride film 15 and the inter- layer insulation film 14 of the protruding part 14a is eliminated, thus exposing the inter-layer insulation film 14 at the silicon nitride film 15.  After that, a via hole 14c where the upper surface of the lower layer wiring 13 is exposed is formed by performing anisotropic dry etching to the interlayer insulation film 14 with a resist pattern 16 and the silicon nitride film 15 as masks.
