Abstract
Embodiments of the disclosure generally relate to methods of adjusting transistor flat band voltage, and transistor gates formed using the same. In one embodiment, a method sequentially includes cleaning a substrate, annealing the substrate in a nitrogen-containing environment to form silicon-nitrogen bonds, hydroxylating the substrate surface, and depositing a hafnium oxide layer over the substrate. In another embodiment, the method further includes depositing an aluminum oxide layer over the substrate prior to depositing the hafnium oxide layer, and then annealing the substrate.
