Abstract
In a static memory cell including first and second drive MOS transistors, first and second MOS transfer transistors and first and second load elements, the drain of the first drive MOS transistor and the source of the first transfer MOS transistor are formed by a first impurity region in a semiconductor substrate, and the drain of the second drive MOS transistor and the source of the second transfer MOS transistor are formed by a second impurity region in the semiconductor substrate. Also, a first metal silicide layer is formed on the first impurity region and the gate of the second drive MOS transistor, and a second metal silicide layer is formed on the second impurity region and the gate of the the drive MOS transistor. Further, the first and second load elements are formed on the first and second metal silicide layers, respectively.
