Problems solved by technology

However, since the conventional printed circuit boards have a low mounting density and the number of pins of semiconductor elements to be mounted is about several thousand to ten thousand pins, it is not necessary to provide small-diameter and narrow-pitch openings.

Abstract

A method for manufacturing a structure containing a conductor circuit according to the present invention can provide openings in various shapes by patterning a first photosensitive resin layer in a first patterning process according to shapes of openings formed in a heat-curable resin layer. Further, in the method for manufacturing a structure containing a conductor circuit, a plurality of openings can be formed at the same time and a residue of the resin around the opening can be reduced, unlike a case in which openings are formed with a laser. Therefore, it is possible to sufficiently efficiently manufacture the structure having excellent reliability even when the number of pins of a semiconductor element increases and it is necessary to provide a great number of fine openings.

Description

[0001] This application is a divisional application with the Chinese application number 201280050024.7 filed on October 9, 2012, and the title of the invention is "Structure with Conductor Circuit and Its Manufacturing Method, and Thermosetting Resin Composition". technical field [0002] The present invention relates to a structure having a conductive circuit, a method for producing the same, and a thermosetting resin composition. Background technique [0003] A printed wiring board, which is one of structures having conductive circuits, is a substrate on which a plurality of wiring layers are formed on a core substrate, and includes a copper-plated film laminate serving as a core substrate, and interlayer insulating layers provided between the wiring layers. material and solder resist on the outermost surface. A semiconductor element is usually mounted on a printed circuit board via a die solder material or an underfill material. In addition, if necessary, the entire surf...
