Abstract:
Apparatus and method for generating ruthenium tetraoxide in situ for use in vapor deposition, e.g., atomic layer deposition (ALD), of ruthenium-containing films on microelectronic device substrates. The ruthenium tetraoxide can be generated on demand by reaction of ruthenium or ruthenium dioxide with an oxic gas such as oxygen or ozone. In one implementation, ruthenium tetraoxide thus generated is utilized with a strontium organometallic precursor for atomic layer deposition of strontium ruthenate films of extremely high smoothness and purity.

Abstract:
A functional perovskite cell formed on a silicon substrate layer and including a functional layer of bismuth ferrite (BiFeO3 or BFO) sandwiched between two electrode layers. An optional intermediate template layer, for example, of strontium titanate allows the bismuth ferrite layer to be crystallographically aligned with the silicon substrate layer. Other barrier layers of platinum or an intermetallic alloy produce a polycrystalline BFO layer. The cell may be configured as a non-volatile memory cell or a MEMS structure respectively depending upon the ferroelectric and piezoelectric character of BFO. Lanthanum substitution in the BFO increases ferroelectric performance. The films may be grown by MOCVD using a heated vaporizer.
