Abstract

PURPOSE: To allow a black body to approach a perfect black body in heat- radiating capability by several to approximately 20% for an improved heat radiating feature, reduced size, and enhanced reliability in an integrated circuit by a method wherein a metal cap is blackened.
CONSTITUTION: A metal cap is blackened so that it may approach a perfect black body in its heat-radiating capability. Such a blackened cap may be built by fabricating into a cap a material that has been carbonized before fabrication, the material may be carbonized after fabrication into a cap, or the surface of the metal cap may be blackened after being seam-welded to a package. Illustrated as an example is a dual in-line package provided with a ceramic portion 1, pins 2, and a metal cap 3 that has been colored black.
