This paper describes a microfabricated linear segmented RF Paul trap for atomic quantum technologies. The microtrap geometry, initially demonstrated in , has been augmented and includes a linear array of trapping segments. Trapping of individual and strings of 88Sr+ ions is demonstrated. The fabrication process has been optimized such that for 80 % of the fabricated devices, the achieved geometry is within ± 5 μm (or ± 3 %) of a prescribed design. This is critical for scalable quantum information processing, where arrays of traps with consistent parameters are required.
