Abstract
A compact SRAM cell and method for its fabrication are disclosed. The small size of the SRAM cell is achieved by fabricating a diode load immediately above the gate electrode of each of the cross coupled transistors of the cell. In accordance with one embodiment, the gate electrode and diode structure include, in sequence, an N-type doped polycrystalline silicon layer, an electrically conductive diffusion barrier layer, a P-type doped polycrystalline silicon layer and an N-type doped polycrystalline layer.
