The resin composition contains a biphenyl aralkyl type epoxy resin (A) represented by the following formula (1), a photocuring initiator (B), a compound (C) represented by the following formula (2), and (C) The compound (D) which has an ethylenically unsaturated group other than a 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 ...
