Abstract:
1. A method of manufacturing a memory device, the method comprising: providing a substrate comprising a silicon-containing surface; providing a vapor comprising one or more refractory metal precursor compounds of the formula MY directing the vapor comprising the one or more precursor compounds of the Formula I to the substrate and allowing the one or more compounds to chemisorb on the silicon-containing surface; providing a vapor comprising one or more disilazanes of the formula (R) directing the vapor comprising the one or more disilazanes to the substrate with the chemisorbed compounds thereon to form a refractory metal nitride barrier layer on the silicon-containing surface; providing a first electrode on the barrier layer; providing a high dielectric material over at least a portion of the first electrode; and providing a second electrode over the high dielectric material.
