Abstract

Abstract A structure and method for a programming device or a fuse includes a capacitive circuit having a capacitance which is alterable. The capacitive circuit can include a first capacitor, a fuse link connected to the first capacitor and a second capacitor connected to the fuse link, wherein removing a portion of the fuse link changes the capacitance.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 65 words
A programming device comprising: a first capacitor; a fuse link connected to said first capacitor; a second capacitor connected to said fuse link, wherein removing at least a portion of said fuse link changes a capacitance of said device; and a sensing circuit operatively connected to said first capacitor and said second capacitor, said sensing circuit being adapted to detect a change in said capacitance.
Claim 2
Dependent Claim 65 words
A programming device comprising: a first capacitor; a fuse link connected to said first capacitor; a second capacitor connected to said fuse link, wherein removing at least a portion of said fuse link changes a capacitance of said device; and a sensing circuit operatively connected to said first capacitor and said second capacitor, said sensing circuit being adapted to detect a change in said capacitance.
Claim 3
Dependent Claim 47 words
The device in claim 1 , wherein said first capacitor includes a first top plate and said second capacitor includes a second top plate, wherein said first top plate, said second top plate and said fuse link are positioned in one planar conductive level within said device.
Claim 4
Dependent Claim 38 words
The device in claim 1 , further comprising an insulator over said fuse link, said fuse link having a length greater than a width of a region formed by said insulator being opened with an energy light source.
Claim 5
Dependent Claim 17 words
The device in claim 1 , wherein said first capacitor and said second capacitor comprise stacked capacitors.
Claim 6
Dependent Claim 17 words
The device in claim 1 , wherein said first capacitor and said second capacitor comprise inter-digitated capacitors.
Claim 7
Dependent Claim 19 words
The device in claim 1 , wherein said first capacitor and said second capacitor comprise parallel spiral patterned capacitors.
