  • Patent number: 11131928
    Abstract: The invention provides a resist underlayer film forming composition which contains a compound having a glycoluril skeleton and which prevents collapse of a resist pattern formed on a substrate in a lithography process during semiconductor production; a resist underlayer film which uses this composition; and a method for producing a semiconductor device. The compound is of formula (1-1), wherein each of R1-R4 represents a C2-C10 alkyl group wherein a hydrogen atom is substituted by at least one substituent selected from the group consisting of a hydroxy group, a thiol group, a carboxyl group, C1-C5 alkoxyethyl groups, C1-C5 alkylsulfanyl groups and organic groups containing an ester bond, or a C2-C10 alkenyl group; the R1-R4 moieties may be the same as or different from each other; and each of R5 and R6 represents a hydrogen atom or a group selected from among C1-C10 alkyl groups and a phenyl group.

  • Patent number: 10610987
    Abstract: In a state where a pair of protrusion portions of a ring portion is clamped by front end engagement portions of a pair of claw members (71) (72), the front end engagement portions of the pair of claw members are swung in a direction approaching each other about a pivotal supporting portion (80). A sliding body (77) slides with the contact of the front end engagement portion to the ring portion or to the protrusion portion thereof so as to follow a radial and circumferential displacement of the protrusion portion accompanying a diameter reduction of the ring portion.
