摘要:
In one embodiment a method of forming a compressive polycrystalline semiconductive material layer is disclosed. The method comprises forming a polycrystalline semiconductive seed layer over a substrate and forming a silicon layer by depositing silicon directly on the polycrystalline silicon seed layer under amorphous process conditions at a temperature below 600 C.
