Claim:
1. A method of forming a microelectronic device, comprising the steps: disposing a substrate of the microelectronic device on a susceptor in a chamber of a metal organic chemical vapor deposition (MOCVD) tool; flowing a first carrier gas into a manifold to combine with a plurality of metal organic precursors in a liquid state, the first carrier gas being chemically inert with respect to the metal organic precursors, a ratio of a flow rate of the first carrier gas to a flow rate of the metal organic precursors in the liquid state being 250 standard cubic centimeters/minute/milliliter/minute (sccm/milliliter/minute) to 500 sccm/milliliter/minute; flowing the first carrier gas combined with the metal organic precursors into a vaporizer, and flowing a second carrier gas into the vaporizer, to convert the metal organic precursors to a gaseous state, the second carrier gas being chemically inert with respect to the metal organic precursors, a ratio of a flow rate of the second carrier gas to a flow rate of the metal organic precursors in the liquid state being 700 sccm/milliliter/minute to 1500 sccm/milliliter/minute; flowing the first carrier gas, the second carrier gas and the metal organic precursors in the gaseous state into the chamber over the substrate, and flowing an oxidizing gas into the chamber over the substrate while the susceptor is heated to 600° C. to 650° C., to form a ferroelectric layer on the substrate; and removing the substrate from the MOCVD tool.
