Definitions
- the present invention relates to a polymer useful as a chemically amplified resist material suitable for microfabrication technology, particularly photolithography, in a manufacturing process of a semiconductor element or the like, a resist material containing the polymer, and a pattern forming method using the resist material.
- lithography refers to exposing a substrate surface coated with a photosensitive substance (photoresist, hereinafter simply referred to as resist) to a desired pattern.
- the lithography technique is a technique for forming a resist pattern on a substrate due to a difference in solubility between a exposed portion of a resist and an unexposed portion by a developer.
- lithography using an argon fluoride (hereinafter abbreviated as ArF) excimer laser that oscillates ultraviolet light having a wavelength of 193 nm is being introduced in earnest.
- ArF argon fluoride
- the ArF excimer laser described above has been put into practical use, and in the future, aiming for the practical use of Extreme Ultra Violet (hereinafter abbreviated as EUV) lithography using extreme ultraviolet light (wavelength 13.5 nm) having a shorter wavelength. Research is underway.
- EUV Extreme Ultra Violet
- a stepper type exposure apparatus is an apparatus that reduces a reticle pattern, which is a kind of high-performance photomask, with a reduction projection lens and exposes it on a resist on a wafer.
- the resolution of a lens used in a stepper type exposure apparatus is NA. Although expressed by (numerical aperture), in air, NA of about 0.9 is regarded as a physical limit and has already been achieved.
- Resist materials having good adhesion to substrates such as wafers are indispensable for fine and accurate pattern formation, and various companies are energetically continuing to research and develop new adhesion monomers.
- Patent Document 1 discloses 5-methacryloyloxy-2,6-norbornanecarbolactone as a photoresist composition. As described above, a monomer having a polar functional group other than a lactone is hardly used in a resist although it can be expected to have sufficient adhesion.
