Abstract: An atomic layer deposition method is used to deposit a TiN or TiSiN film having a thickness of about 50 nm or less on a substrat. A titanium precursor which is tetrakis(dimethylamido)titanium (TDMAT), tetrakis(diethylamido)titanium (TDEAT), or Ti{OCH(CH3)2}4 avoids halide contamination from a titanium halide precursor and is safer to handle than a titanium nitrate. After a monolayer of the titanium precursor is deposited on a substrate, a nitrogen containing reactant is introduced to form a TiN monolayer which is followed by a second purge. For TiSiN, a silicon source gas is fed into the process chamber after the TiN monolayer formation. The process is repeated several times to produce a composite layer comprised of a plurality of monolayers that fills a contact hole. The ALD method is cost effective and affords an interconnect with lower impurity levels and better step coverage than conventional PECVD or CVD processes.

Abstract: A method of forming a channel region for a MOSFET device in a strained silicon layer via employment of adjacent and surrounding silicon-germanium shapes, has been developed. The method features simultaneous formation of recesses in a top portion of a conductive gate structure and in portions of the semiconductor substrate not occupied by the gate structure or by dummy spacers located on the sides of the conductive gate structure.

The recessing of the conductive gate structure and of semiconductor substrate portions reduces the risk of silicon-germanium bridging across the surface of sidewall spacers during epitaxial growth of the alloy layer, thus reducing the risk of gate to substrate leakage or shorts.

Abstract: In a copper plating process, a seed layer is uniformly deposited over a surface, including lining a high aspect ratio trench defined by that surface. A mask layer is provided using a process that fails to deposit in the trench. In one exemplary embodiment, the failure is due to the decrease in the isotropic flux of neutrals toward the bottom of the trench. Copper is subsequently electroplated. Because the seed layer is exposed only within the trench, copper deposits only therein. The self-aligned mask prevents plating outside of the trench. A chemical-mechanical planarization step removes the mask and the seed layer extending beyond the trench, leaving a copper structure within the trench. The structure may serve as a conductive line, an interconnect, or a capacitor plate.
