The microwave properties and the crystal structure of YBa2CU3O7-δ thin films are examined as a function of film thickness. Already below the critical thickness for the formation of macroscopic fractures, we observe an increase of the residual surface resistance with thickness. Cross-sectional transmission electron microscopy reveals that this behavior is caused by structural changes of antiphase boundaries leading to normal-conducting regions between superconducting grains. The surface resistance is calculated within the weak-link picture.
