The quest for new cuprates compounds exhibiting superconducting properties at elevated temperatures was intensified recently. The synthesis under high pressure led first to an increased Tc record of around 160K with Hg compounds, and second to new bulk compounds including Cu, CO3 and infinite layer families. Meanwhile the results concerning thin films of new cuprates, even grown by atomic layering, were not as convincing. We describe here the growth of infinite layer related compounds with emphasis on the growth mechanisms. The deposition is performed in the range of 500 to 550 degrees C under atomic oxygen, using real time control by RHEED intensity. Various deposition sequences were used leading mainly to two basic families. The first one belongs to the infinite layer family, while the other one seems to belong to the spin ladder Can-1Cun+1O2n family. Transport properties in a wide range of temperatures are presented and discussed.
