  • Patent number: 11315773
    Abstract: An ion trap device is disclosed with a method of manufacturing thereof including a substrate, first and second RF electrode rails, first and second DC electrodes on either upper or lower side of substrate, and a laser penetration passage connected to ion trapping zone from outer side of the first or second side of substrate. The substrate includes ion trapping zone in space defined by first and second sides of substrate separated by a distance with reference to width direction of ion trap device. The first and second RF electrode rails are arranged in parallel longitudinally of ion trap device. The first RF electrode is arranged on upper side of first side, the second DC electrode is arranged on lower side of first side, the first DC electrode is arranged on upper side of second side, and the second RF electrode rail is arranged on lower side of second side.

  • Patent number: 10248911
    Abstract: An ion trap device is provided as well as a method of manufacturing the ion trap device including a substrate, central DC electrode, RF electrode, side electrode and an insulating layer. Disposed over the substrate, the central DC electrode includes DC connector pad and DC rail connected thereto. The RF electrode includes RF rail adjacent to the DC rail and RF pad connected to RF rail. The side electrode has RF electrode disposed between thereof and the central DC electrode. The insulating layer supports one of the central DC electrode, RF electrode and side electrode, on a top surface of the substrate. The insulating layer includes first insulating layer and second insulating layer disposed over the first insulating layer, and the second insulating layer includes an overhang protruding with respect to the first insulating layer in a width direction of the ion trap device.
