摘要:
Within a method for forming a silicon layer, there is employed at least one sub-layer formed of a higher crystalline silicon material and at least one sub-layer formed of a lower crystalline silicon material. The lower crystalline silicon material is formed employing a hydrogen treatment of the higher crystalline silicon material. The method is particularly useful for forming polysilicon based gate electrodes with enhanced dimensional control and enhanced performance.
