    摘要: In some embodiments, silicon-filled openings are formed having no or a low occurrence of voids in the silicon fill, while maintaining a smooth exposed silicon surface. In some embodiments, an opening in a substrate may be filled with silicon, such as amorphous silicon. The deposited silicon may have interior voids. This deposited silicon is then exposed to a silicon mobility inhibitor, such as an oxygen-containing species and/or a semiconductor dopant. The deposited silicon fill is subsequently annealed. After the anneal, the voids may be reduced in size and, in some embodiments, this reduction in size may occur to such an extent that the voids are eliminated.

    摘要: An exemplary embodiment of the present invention provides a method of depositing of a film on semiconductor wafers. In a first step, a film thickness of 3 um or less is deposited on wafers accommodated in a wafer boat in a vertical furnace at a deposition temperature of the furnace while a deposition gas is flowing. During the first step, the temperature may be held substantially constant. In a second step, a temperature deviation or variation of at least 50° C. from the deposition temperature of the first step is applied and the furnace temperature is returned to the deposition temperature of the first step while the flow of the deposition gas is stopped. The first and second steps are repeated until a desired final film thickness is deposited.
