Method of protecting circuits using integrated array fuse elements and process for fabrication

In one exemplary embodiment, a detector of electromagnetic radiation includes: a substrate; at least one layer of semiconductor material formed on the substrate, said at least one layer of semiconductor material defining a radiation absorbing and detecting region; an electrical contact configured to couple said region to a readout circuit; and a fuse coupled between the region and the electrical contact. In another exemplary embodiment, a fusible link between a first component and a second component is provided and includes: a fuse with an undercut located underneath at least a portion of the fuse; a first contact coupling the first component to the fuse; and a second contact coupling the second component to the fuse, wherein the undercut is disposed between the first contact and the second contact. In another exemplary embodiment, a fusible link includes a fuse having a layer of material having a negative temperature coefficient of resistance.
