Embodiment

[0345] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to these Examples.

[0346] In addition, the photosensitive resin composition obtained from Examples 1-3 and Comparative Examples 1-2 evaluated the characteristic by the method shown below.

[0347] [1. Evaluation of through-hole resolution]

[0348] (1-1) Production of laminated body for evaluation

[0349] A substrate for a printed wiring board (manufactured by Hitachi Chemical Co., Ltd., manufactured by Hitachi Chemical Co., Ltd., manufactured by laminating copper foil with a thickness of 12 μm on a glass epoxy substrate) was treated with a roughening pretreatment solution (manufactured by MEC Corporation, trade name "CZ-8100"). The surface of the copper foil with the trade name "MCL-E-679") was treated, washed with water, and dried to obtain a substrate for a printed wiring board subjected to a pre-roughening treatment. Next, the protective film was peeled and rem...

Abstract

Provided are: a photosensitive resin composition that has excellent via resolution, adhesive strength to plated copper, crack resistance, and electrical insulation reliability; a photosensitive resin composition for forming photo vias; and a photosensitive resin composition for interlayer insulating layers. Also provided are a photosensitive resin film comprising a photosensitive resin composition and a photosensitive resin film for interlayer insulation layers. In addition, a multilayer printed wiring board and a semiconductor package are provided, as well as a production method for the multilayer printed wiring board. Specifically, the photosensitive resin composition contains a photopolymerizable compound (A) having an ethylenically unsaturated group and a photopolymerization initiator. The photopolymerizable compound (A) having an ethylenically unsaturated group includes a photopolymerizable compound that has an ethylenically unsaturated group (A1), an acidic substituent, and an alicyclic skeleton.

Description

technical field [0001] This indication relates to the manufacturing method of a photosensitive resin composition, a photosensitive resin film, a multilayer printed wiring board, a semiconductor package, and a multilayer printed wiring board. Background technique [0002] In recent years, the miniaturization and high performance of electronic equipment have been promoted, and the density of multilayer printed wiring boards has been increased by increasing the number of circuit layers and miniaturizing wiring. In particular, the density of semiconductor packaging substrates such as BGA (ball grid array) and CSP (chip size package) on which semiconductor chips are mounted is significantly higher, and in addition to miniaturization of wiring, insulation films are also required Thin film and further reduction in diameter of via holes (also referred to as "via holes") for interlayer connection. In addition, with the thinning of insulating films in printed wiring boards, excellent...
