According to one embodiment, an electronic device includes a connector, and a flexible printed wiring board having a board main body provided with a first surface with a conductor provided thereon, a second surface opposite to the first surface, and a front end contacting the connector, and a reinforcing plate contacting the second surface at the front end to reinforce the board main body. A projection is provided on the connector in contact with the flexible wiring board. The reinforcing plate includes a recess portion in which the projection is fitted. The recess portion has a space increased in size toward and opening to an end face of the reinforcing plate corresponding to the front end, and an opening provided in the end face and communicating with the space.
摘要:
An object of the present invention is to make it possible to provide a cord, in particular, a cord for reinforcing a rubber article in which rubber permeation properties are improved by coating filaments as constituents of the cord with rubber in a reliable and stable manner. The cord of the present invention is produced by, when the metal filament is guided to an extruder and extruded together with rubber from a mouthpiece of the extruder so that the metal filament is coated with the rubber, juxtaposing plural metal filaments in the mouthpiece and extruding the metal filaments together with rubber.

There is disclosed a wafer cleaning method comprising supplying a cleaning water to a wafer cleaned with a chemical solution, measuring the resistivity of a solution including the chemical solution and cleaning water, and differentiating the measured value with respect to time, and cleaning the wafer continuously with the cleaning water until the time differential value of the resistivity becomes equal to or less than a preset value and is held at that values for preset time.
摘要:
A method of manufacturing a semiconductor device. In the method, a thin film is formed on an Si substrate having face orientation (100), that part of the thin film, which lies on an element-isolating region, is removed. Then, the Si substrate is subjected to selective etching, making a trench in the substrate to isolate an element, by using the thin film as mask and a mixture solution of hydrofluoric acid and ozone water.

An etching method of subjecting a base material to an etching process using an etching agent containing hydrogen fluoride and ozone is disclosed. The base material has a first region constituted from silicon as a main material and a second region constituted from SiO2 as a main material. The etching method includes the steps of: preparing the base material; and supplying the etching agent onto the base material to form a step between the first and second regions using a feature that an etching rate of silicon by the etching agent is higher than an etching rate of SiO2 by the etching agent, so that the height of the surface of the first region is lower than the height of the surface of the second region.
