Process for forming silicon-filled openings with a reduced occurrence of voids

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.

Provided herein are methods of selectively etching silicon-containing block copolymer (BCP) materials. The methods involve exposing a BCP material that includes at least one silicon-containing block and at least one non-silicon-containing block to a plasma that has a reducing chemistry. The reducing plasma selectively removes the non-silicon-containing block, the silicon-containing block to be used in further processing. In some embodiments, the silicon-containing block is used as an etch mask. The reducing plasma reduces or eliminates profile bowing and undercut of the silicon-containing domains, allowing processing of high aspect ratio features. Examples of reducing chemistries include nitrogen (N.sub.2), hydrogen (H.sub.2), ammonia (NH.sub.3), hydrazine (N.sub.2H.sub.4), and mixtures thereof. Also provided are apparatuses to perform the methods.
