A programmable interconnect device for use in integrated circuits comprises a first conductive layer (12), an insulating layer (14, 16, 18) over said first conductive layer, and a second conductive layer (20) over said insulating layer. There is described the application of a programming voltage to cause the formation of at least one controlled radius filament formed from at least one of said first or second conductive layers, this may have a resistance of less than 300 Ohms. Suitably, the first conductive layer may be a polysilicon and the insulating layer a silicon nitride. The invention also relates to the method of forming such a circuit element on a substrate in a CMOS or bipolar application process. |
