We present surface ion trap chips, industrially fabricated at Infineon Technologies [1,2], that are capable of trapping ions in two separate rf potential wells. The chips are designed for investigating rf shuttling, or radial shuttling, in the large separation and in the coupling regimes as element of a scalable architecture [1]. The design parameters of a surface ion trap in the rf coupling regime with optimal ion height and ion-ion distance are investigated.
The ion traps are fabricated on the dielectric substrates Fused Silica and Sapphire. The advantages of these substrates and the status of industrial microfabrication on these materials are discussed.
