    摘要: Seal coating mask for semiconductor element and method of use thereof with a seal coating mask with an opening located at a position where a semiconductor element is mounted on a wiring board. The coating mask has an annular protrusion formed along the whole periphery of the opening. A clearance of about 0.01 to 0.5 mm is formed between at least a part of the whole periphery of the annular protrusion and the front surface of the wiring board. The coating mask also includes a space portion formed on the back of the seal coating mask for cutting off cooling material outside of the annular protrusion. The coating mask is used to forcibly coat a material for sealing the semiconductor element in the front surface of the wiring board.

    摘要: A method for forming a ferroelectric spontaneous polarization reversal includes the steps of forming a convexo-concave structure on a top face of a ferroelectric substrate firstly, and then forming a ferroelectric spontaneous polarization region on the substrate including one portion of a convex portion, with a concave portion being formed on the bottom face of the substrate within a region where a ferroelectric spontaneous polarization reversal is to be formed and the convex portion is formed, and then applying an electric field into the substrate. The depth of the concave portion on the bottom face of the substrate may be greater than the height of the convex portion on the top face of the substrate. The width of the concave portion on the bottom face of the substrate may be wider than width of said convex portion on the top face of the substrate.

    摘要: A method for forming a ferroelectric spontaneous polarization reversal in a desired region of a ferroelectric substrate includes the steps of forming, for the desired region of the surface of the ferroelectric substrate, an electrode pattern or a mask pattern composed of aggregates of micropatterns, and then applying a given voltage into the desired region. The configuration of the micropatterns can be a stripe-shaped pattern, an ellipse-shaped pattern, a hexagon-shaped pattern, a network pattern, or a double cross shaped pattern. The method can further include the steps of generating many nucleuses by using the electrode pattern or the mask pattern composed of the aggregates of micropatterns, forming another electrode pattern or another mask pattern corresponding to the desired region, and then applying a given voltage into the desired region to generate a ferroelectric spontaneous polarization reversal around the nucleuses.

The wavelength conversion element is realized by comprising a holder and plural prismatic ferroelectric single crystals disposed in the holder, wherein plural prismatic ferroelectric single crystals have at least five planes; the aspect ratios of planes perpendicular to respective longitudinal directions of the plural prismatic ferroelectric single crystals are virtually unity; and each of the plural prismatic ferroelectric single crystals has a domain inversion structure with a predetermined period in the direction perpendicular to the polarization direction thereof, and is arranged in a way that said direction perpendicular to the polarization direction is the same as those of the other crystals. In addition, the element is realized by selecting ferroelectric material from a group comprising lithium niobate, lithium tantalate, impurity-doped lithium niobate, and impurity-doped lithium tantalate, each with virtually stoichiometric composition, and processing it into the cylindrical ferroelectric single crystal with a virtually completely round cross-section.
