Abstract

PURPOSE: To prevent cracks from arising on a package body at cooling by containing the package body with a member of material larger in thermal expansion coefficient than the body.
CONSTITUTION: A ceramic package body 1 and a base 2 consisting of a material smaller in thermal expansion coefficient than the body 1 like Mo are joined at junction 3. A material or copper for example which is larger in thermal expansion coefficient than the body 1 is sticked on the body 1 at its outer perimeter to contain the body 1. The result is such that a compressive force arises with the body 1 at cooling after the body 1 and the base 2 are junctioned, and a tensile stress working from the base 2 can thus be negated, thereby preventing cracks from arising on the body 1.
