Patent ID: 8802492

Claim:
A method for forming resistive switching elements in an atomic layer deposition (ALD) process, the method comprising: depositing a first metal precursor; purging any excess quantity of the first metal precursor; prior to oxidizing the first metal precursor, depositing a first dopant precursor; purging any excess quantity of the first dopant; oxidizing the first metal precursor and the first dopant precursor with a reagent, wherein oxidizing the first metal precursor and the first dopant precursor forms a doped metal oxide, the doped metal oxide being operable as a resistive switching element of a resistive random access memory (RRAM) cell; and purging any excess quantity of the reagent, wherein depositing the first metal precursor, purging any excess quantity of the first metal precursor and depositing the first dopant precursor are performed sequentially.
