摘要

Low temperature deposition methods are needed for realizing large area electronics on alternative substrates like glass, polymer or steel foils. Reasonable electronic quality of low temperature deposited silicon, however, can only be achieved by employing additional, non-thermal sources of energy for promoting and optimizing the surface controlled silicon growth. Methods like very high frequency glow discharge or hot-wire chemical vapour deposition provide a wide range of control over the deposition process, enabling high growth rates, amorphous as well as crystalline silicon deposition and effective hydrogen etching. The current status of these deposition methods is reviewed and the resulting material properties are discussed. Applications like two-terminal colour sensorsand photodiodes for retina implantation demonstrate the potential of joining amorphous and crystalline silicon technology into hybrid sensor systems and teach us how to use the building blocks for novel large area electronics. direct c 1999 Elsevier Science S.A.
