ELECTRONIC ELEMENT SEALING PACKAGE, ELECTRONIC ELEMENT SEALING STRUCTURE, AND MANUFACTURE OF ELECTRONIC ELEMENT SEALING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide electromagnetic shielding effect by providing a base or cap of an electronic element sealing package with a magnetism by dispersing a magnetic metal powder in a ceramic material. ;SOLUTION: Related to an electronic element sealing package 10, a cap 12 formed by extruding a metal material is covered on a base 11 of a ceramic material, to seal an electronic element 16. A magnetic metal powder is diffused in the ceramic used as the material of the base 11 to provide a magnetism, thus the base 11 playing a role for electromagnetic shielding. Thus, nothing affects on the electronic element 16 sealed inside the electronic element sealing package 10, and even when the electronic element 16 sealed inside generates a strong electromagnetic wave, the electromagnetic wave is prevented from leaking outside.;COPYRIGHT: (C)2000,JPO
