Abstract: The method of metallization in semiconductor devices provides a substrate having a conducting region and having an insulating layer formed on the substrate. The insulating layer has a contact hole which exposes the conducting region. Next, a silicon-containing metallization layer and a silicon-free metallization layer are sequentially formed on the insulating layer such that the silicon-containing metallization layer contacts the conducting region through the contact hole. After heat-treating the substrate, the two metallization layers are patterned.
