The thickness and composition of perovskite oxide films were determined by wavelength dispersive X-ray fluorescence analysis (XRF) with special emphasis on the ratio of the group-II elements to the Ti content, and a precision of $0.5\%$ was achieved for a typical film thickness of 20-30 nm. Secondary ion mass spectrometry (SIMS) and sputtered neutrals mass spectrometry (SNMS) was used for depth profiling to determine film homogeneity and elemental interdiffusion at hetero-interfaces. Examples are given for Ba(x)Sr(1-x)TiO(3) and SrTiO(x) thin films which were grown in a prototype MOCVD production tool. No interdiffusion was observed for films grown at 600 degrees C on Pt electrodes in contrast to films grown directly on Si.}, keywords = {J (WoSType)}, cin = {IFF-EKM / ZCH}, ddc = {540}, cid = {I:(DE-Juel1)VDB35 / I:(DE-Juel1)ZCH-20090406}, pnm = {Materialien, Prozesse und Bauelemente für die Mikro- und Nanoelektronik}, pid = {G:(DE-Juel1)FUEK252}, shelfmark = {Biochemical Research Methods / Chemistry, Analytical}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:12707759}, UT = {WOS:000182702300012}, doi = {10.1007/s00216-003-1806-4}, url = {https://juser.fz-juelich.de/record/28931}, }
