Two-dimensional configurations are essential for scalable quantum computation and simulation [1, 2]. We present the concept, fabrication and preliminary results of a 2D ion trap array consisting of parallel 1D ion trap arrays on a microchip. The fabrication is carried out in a state-of-the-art industrial facility ensuring a high process reproducibility. A three-metal-layer structure provides shielding of the substrate and addressing of the DC electrodes across the chip. The design of the 1D arrays allows ion shuttling as well as tuning of the ion-ion distance in the arrays. Additionally, the distance between 1D arrays can be reduced by lowering an RF voltage. These capabilities should enable Coulomb ion-ion coupling in and between the 1D arrays [3].
