| 摘要 |
The present invention provides a method for forming a layer (6) of polycrystalline semiconductor material on a substrate (1). The method comprises providing at least one catalyst particle (4) on a substrate (1), the at least one catalyst particle (4) comprising at least a catalyst material, the catalyst material having a melt temperature of between room temperature and 500° C., or being able to form a catalyst material/semiconductor material alloy with a eutectic temperature of between room temperature and 500° C., and forming a layer (6) of polycrystalline semiconductor material on the substrate (1) at temperatures lower than 500° C. by using plasma enhancement of a precursor gas, thereby using the at least one catalyst particle (4) as an initiator. The present invention furthermore provides a layer (6) of polycrystalline semiconductor material obtained by the method according to embodiments of the present invention. |
