| titleOfInvention | Integrated circuit package |
| abstract | Packages suitable for integrated circuits comprise A. A CERAMIC SUPPORTING ELEMENT OF PREDETERMINED OUTSIDE DIMENSIONS CONSISTING ESSENTIALLY OF FROM ABOUT 35 PERCENT TO ABOUT 45 PERCENT ALUMINUM OXIDE AND THE REMAINDER AN APPROPRIATE SEALING GLASS, THE ELEMENT HAS A SUBSTANTIALLY FLAT LOWER EXTERNAL SURFACE AND AN INTERNAL SEALING SURFACE WITH A SUBSTANTIALLY CENTRALLY LOCATED INDENTATION, B. AN ELECTRICALLY CONDUCTIVE ELEMENT COMPRISING A FRAME PORTION EXTENDING AROUND THE PERIMETER OF THE PACKAGE AND EXTERNAL TO THE CERAMIC SUPPORTING ELEMENT, A CENTRAL PAD PORTION IN THE INDENTATION OF THE SEALING SURFACE OF THE CERAMIC SUPPORTING ELEMENT, AND A PLURALITY OF ELECTRICALLY CONDUCTIVE LEADS EXTENDING INWARDLY FROM THE FRAME PORTION TOWARD THE CENTRAL PAD PORTION AND HAVING AT LEAST ONE LEAD CONNECTED TO THE PAD PORTION AND A MAJOR PORTION OF THE LOWER SURFACE OF THE LEADS IN CONTACT WITH THE SEALING SURFACE OF THE CERAMIC SUPPORTING ELEMENT, C. A CERAMIC SEALING ELEMENT CONSISTING ESSENTIALLY OF FROM ABOUT 20 TO ABOUT 30 PERCENT BY WEIGHT OF ALUMINUM OXIDE AND THE REMAINDER ESSENTIALLY AN APPROPRIATE SEALING GLASS, THE SEALING ELEMENT COVERS A SUBSTANTIAL PORTION OF THE ELECTRICALLY CONDUCTIVE ELEMENT HAVING OUTSIDE DIMENSIONS SUBSTANTIALLY THE SAME AS THE OUTSIDE DIMENSION OF THE CERAMIC SUPPORTING ELEMENT AND CONTAINING AN ACCESS PORT TO THE CENTRAL PAD, THE PORT HAVING PREDETERMINED DIMENSIONS, A LOWER SEALING SURFACE THAT FORMS A SEAL OVER A SUBSTANTIAL PORTION OF THE LEADS AND TO THE SEALING SURFACE OF THE SUPPORTING ELEMENT AND AN UPPER SUBSTANTIALLY FLAT EXTERNAL SURFACE, D. A METALLIC WASHER HAVING AN INSIDE CONFIGURATION SUBSTANTIALLY THE SAME AS THE ACCESS PORT AND IN ALIGNMENT THEREWITH AND THE LOWER SURFACE OF THE WASHER ADHERED TO THE EXTERNAL SURFACE OF THE SEALING ELEMENT. |
