Electrical Fuse Having Resistor Materials Of Different Thermal Stability |
摘要 |
An electrical fuse has a substrate and a resistor. The resistor has a first area and a second area embedded in the first area. The first area is formed of a first material and the second area is formed of a second material having a lower thermal stability than that of the first material. Because of the different thermal stabilities, the second area is more likely to rupture when a programming voltage is applied. The eFuse provides increased reliability and enables lower programming voltages to be used.
