Abstract:
A fabricating method of a semiconductive element includes providing a substrate, wherein an amorphous silicon layer covers the substrate. Then, a titanium nitride layer is provided to cover and contact the amorphous silicon layer. Later, a titanium layer is formed to cover the titanium nitride layer. Finally, a thermal process is performed to transform the titanium nitride layer into a nitrogen-containing titanium silicide layer.

Claim (Index 11):
A fabricating method of a bit line, comprising:\n providing a chamber, wherein the chamber comprises:\n a titanium target disposed on a top wall of the chamber; \n a stage disposed on a bottom of the chamber; \n performing a burn-in process, wherein the burn-in process comprises:\n introducing nitrogen gas and inert gas into the chamber, and ionizing the nitrogen gas and the inert gas to form nitrogen ions and inert ions, wherein the nitrogen ions and inert ions bombard the titanium target to form a first titanium nitride layer on the top wall and the bottom of the chamber; \n after the burn-in process, providing a substrate on the stage, wherein a conductive silicon layer covers the substrate; after providing the substrate on the stage, performing a deposition process, wherein the deposition process comprises:\n introducing inert gas into the chamber, and ionizing the inert gas to form inert ions; \n bombarding the first titanium nitride layer by inert ions to form a second titanium nitride layer to contact the conductive silicon layer; and \n after forming the second titanium nitride layer, the inert ions bombarding the titanium target to deposit a titanium layer to cover the second titanium nitride layer; \n forming a conductive layer to cover the titanium layer; and performing a thermal process to react both the second titanium nitride layer and the titanium layer with the conductive silicon layer to form a nitrogen-containing titanium silicide/titanium silicide layer.
