    Abstract: A showerhead for supplying a gas includes a showerhead body having an upper surface and a lower surface opposite to the upper surface, and a plurality of through-holes formed in the showerhead body so that the gas passes through from the upper surface toward the lower surface, wherein a size of a cross-sectional area of each through-hole of the plurality of through-holes in the lower surface is the same, while the size of the cross-sectional area of each through-hole in the upper surface increases from a center of the showerhead toward an edge thereof.

    Abstract: A substrate processing method capable of forming a film with an improved step coverage on a surface of a gap structure having a high aspect ratio includes: providing a gap structure having a first step and a second step portion; supplying gas including a source gas onto the gap structure; generating active species from the source gas; generating neutral molecules by neutralizing the active species, and moving the neutral molecules in a direction toward a lower surface of a recess extending between the first stepped portion and the second stepped portion; and exciting the neutral molecules moving in the direction toward the lower surface.

    Abstract: A substrate processing method for gap-filling a recess between a first protrusion and a second protrusion of a pattern structure includes: changing a profile of a layer formed on the pattern structure, wherein the changing of the profile of the layer includes: in an upper area, increasing a width of the recess to suppress formation of a void in the upper area; and, in a lower area, reducing the width of the recess to contact the layer, thereby inducing formation of a void under the lower area, and thus allows a position of the void to be adjusted.

    Abstract: A substrate processing method for filling a gap without seams or voids comprising: providing a substrate with a gap in a reaction chamber, pumping down the reaction chamber to a pressure at or below 5 Torr and filling the gap with a film by alternately and sequentially supplying a precursor, a reactant and a radio frequency electromagnetic radiation comprising a relatively high radio frequency component and a relatively low radio frequency component.
