Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
59 words
An integrated circuit fuse link, including: a fuse portion capable of generating heat in response to an applied current; and an exothermic charge positioned adjacent to the fuse portion for blowing the fuse portion, the exothermic charge including exposed photoresist and explosive material, the explosive material being capable of detonating in response to heat generated by the fuse portion.
Claim 2
Dependent Claim
59 words
An integrated circuit fuse link, including: a fuse portion capable of generating heat in response to an applied current; and an exothermic charge positioned adjacent to the fuse portion for blowing the fuse portion, the exothermic charge including exposed photoresist and explosive material, the explosive material being capable of detonating in response to heat generated by the fuse portion.
Claim 3
Dependent Claim
14 words
The integrated circuit fuse link of claim 1, wherein the explosive material includes nitrocellulose.
Claim 4
Dependent Claim
16 words
The integrated circuit fuse link of claim 1, wherein the explosive material includes cellulose acetate buterate.
Claim 5
Dependent Claim
40 words
The integrated circuit fuse link of claim 1, wherein the explosive material detonates in response to heat from the fuse portion that is generated by the fuse portion at a temperature less than the melting temperature of the fuse portion.
