摘要:
A laminated electronic device comprises two or more wiring layers including a first wiring layer and a second wiring layer, an insulating layer interposed between the first wiring layer and second wiring layer, and a through conductor extending through the insulating layer for electrically connecting a first conductor disposed on the first wiring layer to a second conductor disposed on the second wiring layer. The through conductor includes divergent sections at both ends, which have a diameter gradually increased toward the first conductor or second conductor.

An oxide source material solution for forming an oxide film having a composition expressed by PbuZrxTi1-x-yMyO3 is presented. A composition of metal element constituents in the oxide source material solution is expressed by [Pb]:([Zr]+[Ti]+[M])=v:1, and a difference (v−u) in composition ratio of Pb between the oxide source material solution and the oxide film is 0.01 or less.

A plated substrate includes a substrate, a resin formed body having a specified pattern including catalytic metal that functions as a catalyst for electroless plating, and a metal layer formed on a top surface of the resin layer.
摘要:
A method for manufacturing a wiring substrate includes the steps of: (a) forming a sacrificial layer in a first pattern on a substrate; (b) forming a catalyst layer in a second pattern on the substrate; (c) immersing the substrate in an electroless plating liquid, thereby depositing a metal layer on the catalyst layer in the second pattern; and (d) heating to remove the sacrificial layer and to form a metal layer in a third pattern, wherein the third pattern is a region where the first pattern and the second pattern overlap each other.

A method of manufacturing a capacitor, including: forming a lower electrode on a substrate; forming a dielectric film of a ferroelectric or a piezoelectric on the lower electrode; forming an upper electrode on the dielectric film; and forming a silicon oxide film so that at least the dielectric film is covered with the silicon oxide film, the silicon oxide film being formed by using trimethoxysilane.
摘要:
A piezoelectric laminate including a base and a first piezoelectric layer formed above the base and including potassium sodium niobate. The first piezoelectric layer is shown by a compositional formula (KaNa1-a)xNbO3, “a” and “x” in the compositional formula being respectively 0.1
摘要:
A method for manufacturing a wiring substrate by an electroless plating method that precipitates metal without using a plating resist is provided. The method includes the steps of (a) providing a catalyst layer having a predetermined pattern on a substrate; (b) dipping the substrate in an electroless plating solution to thereby precipitate metal on the catalyst layer to provide a first metal layer; (c) washing a top surface of the substrate with water; and (d) dipping the substrate in an electroless plating solution to thereby precipitate metal on the first metal layer to provide a second metal layer.
