摘要:
A polishing liquid composition is applicable as a means of forming embedded metal interconnections on a semiconductor substrate. In a surface to be polished comprising an insulating layer and a metal interconnection layer, the polishing liquid composition is capable of maintaining a polishing speed of the metal layer, of suppressing an etching speed, and of preventing dishing of the metal layer.

摘要:
A polishing composition comprising an improver of a ratio of a polishing rate of an insulating film to that of a stopper film, wherein the polishing rate of the stopper film is selectively decreased, comprising one or more compounds selected from the group consisting of a monoamine or diamine compound; a polyamine having three or more amino groups in its molecule; an ether group-containing amine; and a heterocyclic compound having nitrogen atom. The polishing composition can be used for removing an insulating film which has been embedded for isolation into a trench formed on a silicon substrate and sedimented outside the trench, thereby planing a surface of the silicon substrate.

Process for producing a molded article comprising pouring or injecting a liquid molding material into a mold in the presence of a surface-treating agent comprising a contact angle-reducing substance under the condition that the contact angle between the liquid molding material and the inner surface of the mold is not more than 30°, and curing the liquid molding material; surface-treating agent comprising a contact angle-reducing substance which reduces the contact angle between the liquid molding material and a flat plate made of the same material as the mold to not more than 30°; method for reducing surface voids during molding, comprising using the above surface-treating agent; and use of the above surface-treating agent for reducing surface voids. The molded article has a shape accurately corresponding to the shape of an inner surface of a mold.
摘要:
A polylactic acid resin composition containing a polylactic acid resin; and a compound represented by the formula (I), the compound being contained in an amount of from 0.1 to 30 parts by weight, based on 100 parts by weight of the polylactic acid resin; a sheet obtained with the composition, a stretched film or thermoformed article obtained by secondary forming of the sheet; and a wrapping material made of the stretched film or thermoformed article. The polylactic acid resin composition of the present invention can be suitably used in various industrial applications, such as daily sundries, household electric appliance parts, and automobile parts.
摘要:
A supporting shaft 11 that can be inserted through a center hole 5a in each of cured resin disks 5 and which has a bottom plate in a disk form at an end, as well as a plurality of spacer disks 12 each having a center hole through which the supporting shaft 11 can be inserted are used in the process of manufacturing GC (glass-like carbon) by baking to carbonize the cured resin disks 5. The cured resin disks 5 are stacked alternately with the spacer disks 12 on the supporting shaft 11 in an erect position that is inserted through the center holes in each of the cured resin and spacer disks. The stack is then baked in a baking furnace. By so doing, the cured resin disks can be set up easily and the baking furnace can be operated to its full capacity.
