摘要:
A yeast extract containing a peptide, such as γ-Glu-X and γ-Glu-X-Gly, wherein X can represent an amino acid or an amino acid derivative other than Cys and derivatives thereof, is prepared by culturing a yeast in a medium containing a peptide such as γ-Glu-X, γ-Glu-X-Gly and X-Gly, and preparing a yeast extract from the obtained cells.

A pattern forming method includes (a) coating a substrate with a resist composition including a resin that includes a repeating unit represented by a following general formula (NGH-1), and, by the action of an acid, increases the polarity and decreases the solubility in a negative developing solution; (b) exposing; and (d) developing with a negative developing solution: wherein RNGH1 represents a hydrogen atom or an alkyl group; and RNGH2 to RNGH4 each independently represents a hydrogen atom or a hydroxyl group, provided that at least one of RNGH2 to RNGH4 represents a hydroxyl group.
摘要:
A pattern forming method comprising a step of applying a resist composition whose solubility in a negative tone developer decreases upon irradiation with an actinic ray or radiation and which contains a resin having an alicyclic hydrocarbon structure and a dispersity of 1.7 or less and being capable of increasing the polarity by the action of an acid, an exposure step, and a development step using a negative tone developer; a resist composition for use in the method; and a developer and a rinsing solution for use in the method, are provided, whereby a pattern with reduced line edge roughness and high dimensional uniformity can be formed.
