Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
An insulating package for mounting one of different kinds of semiconductor chip thereon, comprising: a first area formed in a central area of a ceramic body, and assigned to said different kinds of semiconductor chip, said first area comprising a rectangular recess; a second area provided on said ceramic body, and extending along a periphery of said rectangular recess so as to be contiguous to said first area; and a plurality of conductive stitches formed on said second area, and divided into a first group shared between said different kinds of semiconductor chip for forming electrical paths between said one of different kinds of semiconductor chip and an external electrical component and second groups provided on both sides of said first group and selectively used for said different kinds of semiconductor chip so as to form other electrical paths between said one of different kinds of semiconductor chip and said external electrical component.
Claim 2
Dependent Claim
153 words
An insulating package for mounting one of different kinds of semiconductor chip thereon, comprising: a first area formed in a central area of a ceramic body, and assigned to said different kinds of semiconductor chip, said first area comprising a rectangular recess; a second area provided on said ceramic body, and extending along a periphery of said rectangular recess so as to be contiguous to said first area; and a plurality of conductive stitches formed on said second area, and divided into a first group shared between said different kinds of semiconductor chip for forming electrical paths between said one of different kinds of semiconductor chip and an external electrical component and second groups provided on both sides of said first group and selectively used for said different kinds of semiconductor chip so as to form other electrical paths between said one of different kinds of semiconductor chip and said external electrical component.
Claim 3
Dependent Claim
117 words
The insulating package as set forth in claim 1, in which said first group is positioned in a central portion of one of four sub-areas of said second area opposite to one of four edges forming said periphery, and said second groups includes first and second side groups provided on both first side areas of said central portion and third and fourth side groups provided on both second side areas of said first side areas, said first and second side groups being electrically connected to said third and fourth side groups, respectively, so as to selectively use said first and second side groups and said third and fourth side groups for said different kinds of semiconductor chips.
Claim 4
Dependent Claim
47 words
The insulating package as set forth in claim 2, further comprising three sets of conductive stitches respectively provided in three of said four sub-areas, and each set of conductive stitches is similar to said plurality of conductive stitches divided into said first group and said second groups.
Claim 5
Dependent Claim
46 words
The insulating package as set forth in claim 2, in which said first group and one of said first and second side groups and said third and fourth side groups are connected by conductive bonding wires to said one of said different kinds of semiconductor chip.
