  • Patent number: 9006111
    Abstract: A pattern-formation process including: providing a substrate material having on a major surface a difficult-to-access recess formed by a 1st mask; depositing a 2nd mask having a higher etching resistance than the 1st mask by physical evaporation on the upper surface of the 1st mask and peripherally on a side of the recess, the second mask forming a series of films; and etching the substrate material via the 1st and 2nd mask, wherein forming the 2nd mask includes depositing the 2nd mask material by physical evaporation vertically onto the major surface of the substrate material; and the recess is sized such that, upon deposition, the 2nd mask material cannot substantially reach the bottom of the recess. Accordingly, portions of the recesses formed by the etching masks can be processed by etching even when those recesses are 25 nm or less, and especially 20 nm or less in size.
