Method for preventing the etch transfer of sidelobes in contact hole patterns
InactiveUS6905621B2Inhibit transferLarge processing windowDecorative surface effectsPhotomechanical apparatusPhotoresistResist
A method is provided for removing sidelobes that are formed when patterning a positive photoresist layer with an Att. PSM, Alt. PSM or a binary mask with scattering bars. A water soluble negative tone photoresist is coated over the positive photoresist pattern and is exposed through a mask having small islands that correspond in shape, size and location to the small holes in the mask used to pattern the positive tone photoresist. After development, exposed negative tone photoresist covers sidelobes formed by the positive tone process. The negative tone photoresist functions as a mask for a subsequent etch transfer of the positive tone pattern into the substrate. A method of aligning openings in a positive tone pattern over the same openings in a negative tone pattern is also useful in preventing sidelobes in the positive tone photoresist from being transferred into the substrate.

A method of manufacturing contact hole is provided. First, a mask layer is formed on a substrate and a plurality of trenches is formed in the mask layer along two directions that cross over each other. The depth of the trenches is not greater than the thickness of the mask layer. However, there is an opening in the mask layer in the place where the trenches cross over each other. The opening exposes the substrate. Part of the substrate exposed by the opening is removed to form a contact hole in the substrate. In photolithography, it is easier to form lines than to form dots. Hence, the dimensions of contact holes are more precisely controlled.
