Abstract

We report here the results of scanning electron microscopy and transmission electron diffraction studies which characterize the improvement in the epitaxial quality of CaF//2 films on Si(100) resulting from two types of post-growth anneal. We compare rapid thermal anneals (RTA's) ex situ with in situ anneals. Both treatments improve the crystalline quality of the CaF//2. RTA treatments also improve the surface morphology and electrical breakdown characteristics. Cracks arising as the result of RTA are characterized and are accounted for by the differential thermal contraction of CaF//2 and Si.
