Superconducting resonators are highly tunable, low-loss coherent macroscopic devices, making them ideal for quantum technology and sensing applications. Recently, these resonators have been paired with van der Waals (vdW) materials to explore their microwave losses, dielectric properties and kinetic inductance. However, creating a hybrid device that only integrates a superconducting resonator with a vdW flake limits the range of materials that can be used. To overcome this limitation, we fabricate a lamella using a focused ion beam (FIB), effectively replicating the flake. This approach offers the added benefit of precise dimensional control, something that is difficult to achieve with exfoliated flakes. The lamella can then be attached in situ to the resonator using a micro-manipulator. In this talk we will show preliminary hybrid devices with lamella developed from conventional and unconventional superconductors.This approach greatly expands the range of materials that can be explored and enables detailed studies of their superfluid density.
