In recent times more and more theoretical and experimental proposals were made to combine ultra cold atoms with solid state systems, be it superconductors, semiconductors or nano structures. One of the crucial points in these projects is the ability to move an ensemble of ultra cold atoms ultra close to the surface one is interested in. This sub-micron trapping will allow the study of effects novel magnetic materials and semi conductor spin systems using Bose Einstein Condensate Microscopy or open the route for hybrid quantum systems. We will present here our experimental scheme to reach sub micron trapping on Atom chips using thin membrane chips to counter Casimir Polder Effects and traps utilizing 2D electron gases. The feasibility of the cryogenic atom chips needed will be investigated and reacted to existing experiments.
