A SILICIDE AGGLOMERATION FUSE DEVICE

摘要

A fusible link device disposed on a semiconductor substrate for providing discretionary electrical connections. The fusible link device of the invention includes a silicide layer and a polysilicon layer formed on the silicide layer and has a first un-programmed resistance. The silicide layer agglomerates to form an electrical discontinuity in response to a predetermined programming potential being applied across the suicide layer, such that the resistance of the fusible link device can be selectively increased to a second programmed resistance.
