- 7. A ceramic package as claimed in claim 5, additionally comprising one or more additional ceramic members having said recess portion, flange portion and metallized layers, said additional ceramic members being secured to one of the first two ceramic members in a manner to enclose an electronic component in each of said additional ceramic members, and being in electrical contact with the metallized layers of at least one of the first and second ceramic members through a through-hole in the bottom surface of at least one of the first and second ceramic members.
- 8. A ceramic package comprising a single monolithic ceramic sheet formed into a primary ceramic body having a recess portion therein with a flange portion disposed at the edge of said recess portion, at least one metallized chip member on an inner bottom surface of the recess portion for mounting an electronic device thereon, and a plurality of metallized layers extending from the inner bottom surface to the flange portion thereof and comprising a conductive path to connect the electronic device to external circuits, further comprising a plurality of metallized conductive layers provided on an outer bottom surface of the ceramic body and a plurality of through-holes extended through the bottom surface, the metallized conductive layers being electrically connected to the metallized layers on the inner bottom surface through the through-holes and a second ceramic body of a size smaller than the bottom surface of the primary ceramic body, said second ceramic body also having a recess portion with a flange portion extending outward from the edge of its recess portion, and at least one metallized chip member on the inner bottom surface of the recess portion of the second ceramic member for mounting an electronic device thereon, and a plurality of metallized layers extending from the inner bottom surface of the second ceramic member to the flange portion thereof, comprising a conductive path to connect the electronic device to external circuits, said second ceramic member being mounted on the outer bottom surface of the primary ceramic member with the metallized layers of the two ceramic members being connected through at least one of the through-holes in the bottom surface of the primary ceramic member.
- 9. A ceramic package comprising a single monolithic ceramic sheet formed into a primary ceramic body having a recess portion therein with a flange portion disposed at the edge of said recess portion, at least one metallized chip member on an inner bottom surface of the recess portion for mounting an electronic device thereon, and a plurality of metallized layers extending from the inner bottom surface to the flange portion thereof and comprising a conductive path to connect the electronic device to external circuits, further comprising a plurality of metallized conductive layers provided on an outer bottom surface of the ceramic body and a plurality of through-holes extended through the bottom surface, the metallized conductive layers being electrically connected to the metallized layers on the inner bottom surface through the through-holes and a second ceramic body of a size smaller than the bottom surface of the primary ceramic body, said second ceramic body also having a recess portion with a flange portion extending outward from the edge of its recess portion, and at least one metallized chip member on an inner bottom surface of the recess portion of the second ceramic member for mounting an electronic device thereon, and a plurality of metallized layers extending from the inner bottom surface of the second ceramic member to the flange portion thereof, comprising a conductive path to connect the electronic device to external circuits, said second ceramic member being mounted on the outer bottom surface of the primary ceramic member with the metallized layers of the two ceramic members being connected through at least one of the through-holes in the bottom surface of the primary ceramic member, and one or more additional ceramic members having said recess portion, flange portion and metallized layers, said additional ceramic members being secured to one of the first two ceramic members in a manner to enclose an electronic component in each of said additional ceramic members, and being in electrical contact with the metallized layers of at least one of the first and second ceramic members through a through-hole in the bottom surface of at least one of the first and second ceramic members.
