Abstract :
The effects of arsenic implants, which form the lower and the upper n+ contact regions of the vertical polycrystalline silicon resistor, on memory switching have been investigated. It is shown that switching in devices without the lower n+ contact is initiated due to Joule heating, whereas in devices without the upper n+ contact, it is electronic in nature. These resistors are suitable for applications in high density `fuse-programmable´ memory technology
