A cooling device for a microcircuit provides a direct path of thermal
extraction from a high heat producing area to a cooler area. A thermal
insulation layer is formed on a body having at least one component
thereon that generates the high heat producing area. At least one via is
formed through an entire thickness of the insulation layer and is in
direct communication with the high heat producing area. Heat from the
high heat producing area is channeled through each via to the cooler
area, which may be ambient atmosphere or a good thermal conductor, such
as a heat sink. A thermal conductive material may be deposited within the
via and increase the rate of thermal extraction therethrough.
