    • PURPOSE: A resin composition for forming resist under film is provided to have anti-reflection barrier layer function, and excellent pattern transfer performance as well as etching-resistive characteristics using a crosslinking agent having specific structure. CONSTITUTION: A resin composition for forming resist under film comprises resin having aromatic ring, cross-linking agent having a partial structure of chemical formula (I). X from the chemical formula(i) is among an oxygen atom or sulfur-atom or *-COO- or -NRA- among the chemical formula (I). RA is a monovalence of a hydrocarbon group of hydrogen atom or carbon number 1-30, and * shows the part combined with R1. R1 is a monovalence of a hydrocarbon group of a hydrogen atom or carbon number. 1-30R2 is a hydroxy group, a sulfonyl group, a cyano group, a nitro group, a monovalence of a hydrocarbon group of carbon number 1-30, monovalence of an oxy hydrocarbon group of carbon number 1-30, or a monovalence of sulfanyl hydrocarbon group of carbon number 1-30. n1 is an integer of 1-12, n2 is an integer of 0-11, and n1+n2 is an integer less than 12. Several X, R1, and R2 are respectively identical or different when X, R1, and R2 are respectively several. P is an integer of 1-3.
