<p>The present invention makes it possible to fabricate a composite sheet using a multiply layered composite film with a higher anisotropy of heat conductivity obtained by compositely laying a ceramic insulation layer and an electrical conduction layer on a copper thin film so as to increase the horizontal heat conductivity compared to the vertical heat conductivity. Particularly, it is possible to fabricate a composite film with higher horizontal heat conductivity than the vertical heat conductivity that can replace a graphitic heat-diffusion material. To this end is provided a multiply layered composite film with an anisotropic heat conductivity using a copper thin film including an insulation layer and an electrical conduction layer. The present invention proposes a multi-layered composite sheet with a higher anisotropy of heat conductivity obtained by compositely laying a ceramic insulation layer and an electrical conduction layer on a copper thin film so as to increase the horizontal heat conductivity compared to the vertical heat conductivity.</p> |
