Abstract
A method for forming a multilevel interconnection between a polycide layer and a polysilicon layer is disclosed. The multilevel interconnection comprises: forming a first impurity-containing conductive layer on a semiconductor substrate; forming a first silicide layer, having a first region thinner than a second region, on the first impurity-containing conductive layer; forming an interlayer dielectric layer in other than the first region; forming a contact hole for exposing the first silicide layer of the first region; and connecting a second impurity-containing conductive layer to the first silicide layer through the contact hole.
