摘要:
A thin film structure is formed that includes hafnium silicon oxide using an atomic layer deposition process. A first reactant including tetrakis ethyl methyl amino hafnium (TEMAH) is introduced onto a substrate. A first portion of the first reactant is chemisorbed to the substrate, whereas a second portion of the first reactant is physorbed to the first portion of the first reactant. A first oxidant is provided onto the substrate. A first thin film including hafnium oxide is formed on the substrate by chemically reacting the first oxidant with the first portion of the first reactant. A second reactant including amino propyl tri ethoxy silane (APTES) is introduced onto the first thin film. A first portion of the second reactant is chemisorbed to the first thin film, whereas a second portion of the second reactant is physorbed to the first portion of the second reactant. A second oxidant is provided onto the first thin film. A second thin film including silicon oxide is formed on the first thin film by chemically reacting the second oxidant with the first portion of the second reactant.

A method of forming transistor gate structures in an integrated circuit device can include forming a high-k gate insulating layer on a substrate including a first region to include PMOS transistors and a second region to include NMOS transistors. A polysilicon gate layer can be formed on the high-k gate insulating layer in the first and second regions. A metal silicide gate layer can be formed directly on the high-k gate insulating layer in the first region and avoiding forming the metal-silicide in the second region. Related gate structures are also disclosed.
