Infineon Technologies is fabricating 2D and 3D ion trap chips in its industrial facilities [1,2]. This poster gives an overview of our work towards large-scale, reliable ion traps.
We are developing multiple fabrication processes on silicon and dielectric substrates for, e.g., multi-metal stacks with low resistance at cryogenic temperatures, and surfaces resilient to UV laser beam exposure, which we characterize using analytical tools (cryogenic probe station, KPFM microscopy). Together with partners, we design and produce ion traps with integrated optical waveguides, and traps for ion shuttling with ~200 electrodes, that will be operated with a custom cryo-compatible electronic chip. We present a second-generation ion trap socket that allows fast exchange of traps, which we use in our ion trapping lab and make available to our partners.
