Fully closed silicon layers on ECN-made ceramic substrates were grown ina reproducible manner by standard Liquid Phase Epitaxy (LPE). Important conditions for the growing of these layers are: the composition of the melt (In/1%Al), the substrate material, and the temperature trajectory. The experiments show that in order to obtain closed layers on ceramic substrates with standard LPE processing it is necessary that the substrates contain a high density of silicon seeds at the surface. The gas atmosphere, i.e. argon versus argon/hydrogen, appears not to play an important role in this process. Besides standard LPE processing, preliminary experiments were performed with other LPE based-techniques, e.g. the Temperature Difference Method and gas-phase assisted LPE as building blocks in a feasibility study towards a continuous thin film silicon growth process. 5 refs.
