    AbstractIncreasing the HTS film thickness would be the straightforward route to enhance the current transport capacity of coated conductors. Usually, however, growth defects lead to a strong deterioration of the critical current density with thickness. The unique growth mode of HTS films on graded and tilted MgO buffer layers grown by inclined substrate deposition (ISD) paves the way to overcome this limit. This contribution presents micro-structural and performance data of coated conductors with monolithic REBCO-films up to 7.5μm thickness exhibiting perfect crystallinity and critical currents in excess of 1000 A/cm-width
