Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 74 words
A gate array device comprising: a collection of semiconductor elements; fusible links interconnecting the collection of semiconductor elements into an inoperably connected gate array device; and an insulation layer disposed over said collection of semiconductor elements and having discrete apertures overlying said fusible links, said collection of semiconductor elements being interconnected for converting the inoperable gate array device into a selected operable electronic function upon the fusing of predetermined ones of the fusible links.
Claim 2
Dependent Claim 74 words
A gate array device comprising: a collection of semiconductor elements; fusible links interconnecting the collection of semiconductor elements into an inoperably connected gate array device; and an insulation layer disposed over said collection of semiconductor elements and having discrete apertures overlying said fusible links, said collection of semiconductor elements being interconnected for converting the inoperable gate array device into a selected operable electronic function upon the fusing of predetermined ones of the fusible links.
Claim 3
Dependent Claim 20 words
A gate array device according to claim 1 and wherein said semiconductor elements comprise transistors formed on a silicon substrate.
Claim 4
Dependent Claim 53 words
A gate array device according to claim 1 and wherein said fusible links comprise a first plurality of connection links operative to provide a plurality of connections between individual semiconductor elements to define functional groupings thereof and a second plurality of connection links operative to provide a plurality of connections between functional groupings.
Claim 5
Dependent Claim 33 words
A gate array device according to claim 2 and wherein said gate array device includes a least two metal layers and fusible links formed on each of said at least two metal layers.
