Abstract
A heat sink mounted on a semiconductor chip module sealed hermetically with a cap. The heat sink includes an absorption portion for absorbing the heat generated by a semiconductor chip. The absorption portion is inserted into an opening formed in a cap to contact a semiconductor chip sealed hermetically within the cap. The heat sink further includes a heat dissipation portion exposed outside the cap for dissipating the heat of the semiconductor chip absorbed by the absorption portion.
