Abstract: A plate-shaped carbon fiber-reinforced carbon composite has a longitudinal length-to-widthwise length ratio of more than 1. The carbon fiber-reinforced carbon composite is such that at least two layers that are a first carbon fiber-reinforced carbon composite layer in which carbon fibers are placed in the carbonaceous matrix and are oriented in the longitudinal direction and a second carbon fiber-reinforced carbon composite layer different in the arrangement of the carbon fibers from the first carbon fiber-reinforced carbon composite layer are stacked, the first carbon fiber-reinforced carbon composite layer forms an outermost layer of at least one plate surface, the thickness thereof is 70% or more of the thickness of the carbon fiber-reinforced carbon composite, and the longitudinal bending elastic modulus is 150 GPa or more. The first carbon fiber-reinforced carbon composite layer in which the carbon fibers are aligned in the longitudinal direction is placed only on an outermost layer of one or both of plate surfaces and another site is a carbon fiber-reinforced carbon composite layer different in the arrangement of the carbon fibers from the first carbon fiber-reinforced carbon composite layer; hence, the longitudinal bending elastic modulus is significantly increased and warping, peeling, or cracking during usage and interlayer delamination due to gases produced during manufacture are suppressed.

Abstract: The present invention provides an etching agent that is able to etch a Cu film by a simple chemical etching method such as an immersion method when the low resistance Cu film is used for a wiring material, while allowing time-dependent changes of the etching rate to be small and preventing a pattern narrowing phenomenon ascribed to irregular amount of side etching of the Cu film from occurring, by providing an etching agent comprising an aqueous solution containing potassium hydrogen peroxosulfate and hydrofluoric acid, wherein masks of a give pattern is formed on the surface of a laminated film prepared by sequentially depositing a Ti or Ti alloy film and a Cu film on a substrate, and wherein a gate electrode (a laminated wiring) and a lower pad layer (a laminated wiring) with give patterns are formed by etching the laminated film using the etching agent having the foregoing construction.
