Abstract

Provided is a resin composition that, when used in a multilayer printed circuit board, exhibits superior heat resistance and coating, and exhibits superior plating adhesion and developability. Also provided are a resin sheet with a support body, and a multilayer printed circuit board and a semiconductor device that use said resin composition and said resin sheet with a support body. The resin composition includes a biphenyl aralkyl-type epoxy resin (A) expressed by formula (1), a photocuring initiator (B), a compound (C) expressed by formula (2), and a compound (D) that has an ethylenically unsaturated group other than the (C) component.

Description

technical field [0001] The present invention relates to a resin composition, a resin sheet using the same, a multilayer printed wiring board, and a semiconductor device. Background technique [0002] Due to the miniaturization and high density of multilayer printed wiring boards, researches on reducing the thickness of laminated boards used in multilayer printed wiring boards are being actively carried out. Along with the thinning, the insulating layer is also required to be thinned, and a resin sheet that does not contain glass cloth is required. The main resin composition used as a material of the insulating layer is a thermosetting resin, and drilling for obtaining conduction between the insulating layers is usually performed by laser processing. In addition, as a method of forming a conductive circuit on an insulating layer for a resin sheet using a thermosetting resin, a method of forming a conductive circuit by copper plating is generally used. [0003] On the other ...
