Abstract
PURPOSE: To prevent alpha-particles from invading from a very small amount of a radioactive substance into a semiconductor chip in a container, by making a part of the lid of the container from a semiconductor.
CONSTITUTION: The reverse side of a semiconductor chip 1 is bonded on a container 2. A silicon crystal plate 4 of 100μ in thickness is bonded on the lid 3 of the container. The lid 3 and the container 2 are bonded on each other. No alpha-particles go into the semiconductor chip 1 from a very small quantity of a radioactive substance of the container 2 and from the lid 3 because the thickness of chip is 100μ or more and the semiconductor 4 is bonded on the lid. Alpha-particles are thus prevented from invading into the semiconductor chip 1.
