    摘要: High dielectric films of mixed transition metal oxides of titanium and tungsten, or titanium and tantalum, are formed by sequential chemical vapor deposition (CVD) of the respective nitrides and annealing in the presence of oxygen to densify and oxidize the nitrides. The resulting film is useful as a capacitative cell and resists oxygen diffusion to the underlying material, has high capacitance and low current leakage.

    摘要: The present invention substantially removes dry etch residue from a dry plasma etch process 110 prior to depositing a cobalt layer 124 on silicon substrate and/or polysilicon material. Subsequently, one or more annealing processes 128 are performed that cause the cobalt to react with the silicon thereby forming cobalt silicide regions. The lack of dry etch residue remaining between the deposited cobalt and the underlying silicon permits the cobalt silicide regions to be formed substantially uniform with a desired silicide sheet and contact resistance. The dry etch residue is substantially removed by performing a first cleaning operation 112 and then an extended cleaning operation 114 that includes a suitable cleaning solution. The first cleaning operation typically removes some, but not all of the dry etch residue. The extended cleaning operation 114 is performed at a higher temperature and/or for an extended duration and substantially removes dry etch residue remaining after the first cleaning operation 112.

    摘要: An improved method of forming a fully silicided (FUSI) gate in both NMOS and PMOS transistors of the same MOS device is disclosed. In one example, the method comprises forming oxide and nitride etch-stop layers over a top portion of the gates of the NMOS and PMOS transistors, forming a blocking layer over the etch-stop layer, planarizing the blocking layer down to the etch-stop layer over the gates, and removing a portion of the etch-stop layer overlying the gates. The method further includes implanting a preamorphizing species into the exposed gates to amorphize the gates, thereby permitting uniform silicide formation thereafter at substantially the same rates in the NMOS and PMOS transistors. The method may further comprise removing any remaining oxide or blocking layers, forming the gate silicide over the gates to form the FUSI gates, and forming source/drain silicide in moat areas of the NMOS and PMOS transistors.
