Abstract: <P>PROBLEM TO BE SOLVED: To provide a metal roof material and structure prevented from being smashed under the feet, less liable to be peeled, and suppressing the moisture of a roof substrate.  <P>SOLUTION: This metal roof material is formed into a metal roof structure by parallel forming a plurality of projecting linear bodies of a steel plate, etc., to each other in the left/right direction, forming connecting parts in the front/rear parts of the linear bodies, and connecting the linear bodies at the connecting parts. When the plurality of linear bodies are connected to the metal roof material formed by alternately disposing small and large cross section areas, the linear bodies, a connecting passage, and a fitting body and formed into the metal roof structure, this metal roof structure is so formed that the communication passage side end part is singularly and directly connected to each roof substrate by screws and the fitting side end part is connected to each roof substrate by screws along with other metal roof material to be the bottom thereof. The metal roof structure leads and allows the air under a flattened part to pass upward with the linear body at the communication passage and to flow out from the upper end of the roof structure. This constitution can thus prevent the structure from being smashed under the feet, prevent the peeling of the roof material due to a strong wind, remove the moisture in the roof substrate, and prevent the roof substrate from getting to high temperature.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a simple and highly efficient laser annealing process wherein diameters of crystal grains in a crystallized semiconductor film are made gigantic with excellent uniformity, in a thin-film transistor and a manufacturing method thereof.  <P>SOLUTION: A reflective film 3 for reflecting a laser beam wavelength is formed on a substrate 1 via an underlying film 2 to face the end side of an island-like a-Si film 5. Then, the upper surface of the substrate is vertically irradiated with a laser beam (a). A region having the reflective film 3 is double- heated by the direct beam and the reflected beam of the laser beam (a), and the region having no reflective film 3 is heated by only the direct beam of the laser beam (a). Thus, both ends of the island-like a-Si film 5 are separated into higher and lower temperature parts to form a temperature gradient. The heat from the island-like a-Si film 5 is efficiently given to the substrate 1, but the cooling of the higher temperature part is delayed so that the crystal of a p-Si film as a crystallized semiconductor film is grown laterally from the higher to the lower temperature part. Thus, Si crystal grains of large grain diameters can be obtained with excellent uniformity.  <P>COPYRIGHT: (C)2003,JPO
