Patent ID: 8133758

Claim:
A method of fabricating a phase-change memory device, the phase-change memory device comprising a memory cell including a switching device and a phase change pattern, the method comprising: forming a TiC layer on a contact electrically connecting the switching device using a plasma enhanced cyclic chemical vapor deposition (PE-cyclic CVD) process, wherein forming the TiC layer comprises: loading a substrate including the contact plug into a reaction chamber capable of performing the PE-cyclic CVD process; and repeatedly performing a deposition cycle including a purge operation and a feeding operation on the substrate between 20 and 30 times, wherein during the purge operation an inert gas is supplied to the reaction chamber, and during the feeding operation a titanium source gas, a carbon source gas and the inert gas are supplied to the reaction chamber; patterning the TiC layer to form a lower electrode on the contact; and forming the phase-change pattern on the lower electrode.
