Abstract
A low temperature CVD process using a tris (&bgr;-diketonate) bismuth precursor for deposition of bismuth ceramic thin films suitable for integration to fabricate ferroelectric memory devices. Films of amorphous SBT can be formed by CVD and then ferroannealed to produce films with Aurivillius phase composition having superior ferroelectric properties suitable for manufacturing high density FRAMs.
