3 Designs Procedure for the ResonatorsIn order to have a spatial tolerance at the connection from the center conductor of theconnector to the one of the resonator structure the inner strip of the tapering structure wasdesigned to have a diameter of 800 µm.For this dimension no matching to 50 Ω is possible within CPW technology. In order tominimize the effect of mismatch, the dimensions of the gap were adapted to the width of thedielectric of the connector. This avoids a parasitic reactance produced by discontinuities ingeometry.30
4 Fabrication and Measurement Setup4.1 Fabrication ProcessAll resonators were fabricated in the cleanroom facilities at the Walther-Meißner-Institut.Two optical masks with several different resonator geometries were designed within thisdiploma thesis and ordered from ML&C 1 . The relevant dimensions and design rules of theresonators are given in chapter 3 on page 27. An overview of the masks is found in AppendixB on page 73.Figure 4.1 shows the different fabrication steps.Figure 4.1: Overview of the Niobium CPW fabrication process.1 www.mlc-jena.de31
