    Abstract: A method for manufacturing EPROM tunnel oxide cell having a damage-free source region. The method comprises the step of providing a substrate having a device region formed thereon, and then forming an ion-implanted region in the device area. Next, a gate oxide layer is formed over the substrate. Subsequently, a floating gate, a dielectric layer, a control gate and an oxide layer are sequentially formed above the substrate. This invention utilizes the implantation of a moderately heavy dose of ions into a device area prior to the formation of the gate oxide layer, so that a thicker gate oxide layer is formed above the source region. Hence, when the first polysilicon layer is etched in a subsequent self-aligned etching operation to establish the common source region, the thicker gate oxide layer can serve as a protective layer for the source region.

    Abstract: An method for the formation of polycide used for the gate electrode or interconnection metallization in semiconductor integrated circuit devices has been developed. The polycide is formed from doped amorphous silicon deposited from SiH.sub.4 and PH.sub.3 and tungsten silicide deposited from dichlorosilane (SiH.sub.2 Cl.sub.2 and WF.sub.6, followed by conventional RIE patterning. The key feature, annealing of the polycide structure by a combination of RTA (Rapid Thermal Anneal) in a nitrogen ambient, and then a furnace anneal in an oxygen ambient prevents deleterious sidewall growth on the polycide structure and results in a highly manufacturable process having high yield.
