摘要

PROBLEM TO BE SOLVED: To obtain a highly heat conductive sheet having high anisotropic thermal conductivity in thickness direction, capable of efficiently removing heat from a heating element such as semiconductor element or semiconductor package, excellent in heat resistance, durability and mechanical strength and also excellent in adhesion to heating element.;SOLUTION: This composition for highly heat conductive sheet is characterized by orientating carbon fiber 3 attaching a magnetic material on the surface in a binder in a direction of thickness of the highly heat conductive sheet in a binder 2 in curing or semi-curing state. This method for producing a highly heat conductive sheet 1 is characterized by making magnetic field to act on the above sheet-like composition in a direction of thickness and curing or semi- curing the sheet-like composition while orientating carbon fiber 3 attaching a magnetic material on the surface in the direction of thickness of the sheet-like composition.;COPYRIGHT: (C)2001,JPO
