[0065] (electronic device)

[0066] Next, the present invention will be described in detail.

[0067] figure 1 It is a figure which shows and explains the electronic device manufactured using the manufacturing method of the electronic device of this invention, and is figure 2 The side sectional view of A—A line looking down. figure 1 Among them, symbol 1 is the electronic device of the present invention. figure 2 It is a plan view showing a part of the electronic device 1 (resin 35 described later) seen through from a vertical direction, and is a diagram for explaining the electronic device 1 of the present invention.

[0068] Such as figure 1 As shown, the electronic device 1 includes, for example, a substrate 5 made of Si and a pedestal 10 formed on the substrate. The above-mentioned pedestal 10 is, for example, a plate-shaped substrate made of materials such as Si and ceramics. In addition, the above-mentioned pedestal 10 may be an organic substrate, an electronic c...

Abstract

The present invention provides a manufacturing method of an electronic device, which includes the steps of preparing a pedestal with an inclined surface, forming a first wiring on a substrate, and attaching the pedestal with the inclined surface to the substrate through an adhesive layer. In the process on the substrate, the second wiring is simultaneously performed through the upper surface of the inclined surface of the pedestal and the second wiring extending from the upper surface of the pedestal and connected to the first wiring. The process of forming and connecting the first wiring and the second wiring.

Description

technical field [0001] The invention relates to a method for manufacturing an electronic device. Background technique [0002] In recent years, research and development of micro / ultra-high performance electronic components (MEMS) using MEMS (Micro Electro Mechanical System) technology has become popular. Many electronic components using MEMS technology are known, and as one of them, for example, an inkjet head constituting an inkjet printer is known. However, in electronic components (electronic devices) manufactured using MEMS technology and electronic components not manufactured using MEMS technology, due to the limitation of the area of ​​the substrate constituting the electronic component or other reasons, sometimes the wiring formed on the substrate and the wiring mounted on the substrate The terminals of mounted components such as semiconductor chips cannot be directly connected to the substrate surface. [0003] For example, when a semiconductor chip is mounted on a...
