We present a novel planar segmented trapping structure for single or few ions for applications in Quantum Information. The key feature of this trap is a loading zone, which is connected to a Y - junction. Thus, the ion may be shuttled in a controlled way either to the right or to the left arm by using the 58 individually addressable dc-electrodes, which was not possible with planar trapping devices so far [1,2]. We expect complex interaction sequences e.g. the interchange of two ions to be possible in our device. We discuss the geometry and fabrication of the trap electrode structure, where our method allows the inter-electrode gaps are as small as 1.2 to 4.0 µm. We report the electrical tests of the device and its operation with a single ion.
