Multilayer wiring, semiconductor device, substrate for display and display

Abstract

A multilayer wiring, a semiconductor device, a substrate for display and a display, in which the area for placing a wiring layer can be narrowed while suppressing deterioration of characteristics resulting from the parasitic capacitance. The multilayer wiring comprises, from the substrate side, a first conductor located on the (n+1)th conductor layer, a second conductor located on the (n+2)th conductor layer and connected electrically with a conductor located below the (n+1)th conductor layer at least through a first contact hole in the (n+1)th insulating film directly under the (n+2)th conductor layer such that the second conductor does not overlap the first conductor in plan view of the major surface of the substrate, and a third conductor located on the (n+3)th conductor layer and connected electrically with the second conductor through a second contact hole in the (n+2)th insulating film directly under the (n+3)th conductor layer in plan view of the major surface of the substrate and placed on the first conductor side from the second contact hole in the plan view of the major surface of the substrate.

Description

technical field [0001] The present invention relates to multilayer wiring, a semiconductor device, a substrate for a display device, and a display device. More specifically, it relates to a multilayer wiring suitable for mobile devices such as mobile phones, a semiconductor device, a substrate for a display device, and a display device. Background technique [0002] In recent years, portable electronic devices such as mobile phones and PDAs equipped with display devices such as liquid crystal display devices and organic electroluminescence display devices have been increasingly required to be smaller and lighter. Along with this, developments are being made to achieve miniaturization of non-aperture portions, that is, narrower borders, in substrates for display devices included in display devices. [0003] In addition, in order to achieve thinning and cost reduction, there is a tendency to increase the number of display devices provided with all-monolithic display device su...

Problems solved by technology

[0003] In addition, there is a tendency to increase the number of display devices equipped with all-monolithic display device substrates in which peripheral circuits necessary for driving, such as a driver circuit, are formed on the substrate in order to achieve thinning and cost reduction.
