    摘要: A multilayer wiring substrate for a semiconductor having a rectangular coaxial wiring structure and a method of fabrication thereof are disclosed, in which a wiring substrate of high density, and free of crosstalk, can be fabricated by press work using a die. A semiconductor wiring substrate comprises an insulating base substrate (2), a first metal layer (3) formed on the base substrate, a plurality of signal patterns (30) formed on the first metal layer through a dielectric layer (5), a second metal layer (36) formed on the signal patterns through a dielectric layer (31), and metal vias (29, 37) for partitioning the adjacent signal patterns (30) through a dielectric layer. The die is used to form the signal patterns and the vias.

    摘要: A camera has a camera body. A taking lens is disposed at a front face of the camera body, for introducing object light. A grip portion is disposed in the camera body and lower than the taking lens, and adapted to holding of the camera body. A release button is adapted for recording the object light from the taking lens by being depressed, and is disposed between the taking lens and the grip portion. In a preferred embodiment, the release button has a depression surface inclined with reference to the front face of the camera body. Furthermore, an instant photo film chamber is formed in the camera body, disposed behind a central portion of the front face, and contains an instant photo film. A printer unit with an exposure head records an image to the instant photo film.
