Abstract: A method of patterning a substrate includes forming a first line, a second line, and a third line over the substrate, the first line, the second line, and the third line being parallel in a plan view, and forming a fourth line and a fifth line over the first line, the second line, and the third line, the fourth line and the fifth line being orthogonal to the first line in the plan view. The method further includes etching a hole through the second line using the first line, the third line, the fourth line, and the fifth line as an etching mask, and filling the hole with a dielectric material to form a block.

Abstract: A wave power converting device includes a platform, a plurality of first and second fluid guide assemblies and floating assembly. The platform has a retaining post anchored to an underwater ground. The first and second fluid guide assemblies are disposed underwater so that the water could flow into the first and second fluid guide assemblies. The floating assembly could be moved up and down relative to the platform so as to press the water upwardly through the first and second fluid guide assemblies to a reservoir. Under this arrangement, the energy potential of the water in the reservoir can be converted into electrical power.
