Abstract
A method for fabricating a static random access memory (SRAM) includes the steps of forming a first fin-shaped structure for a first pull-down (PD) transistor on a substrate, forming a second fin-shaped structure for a second PD transistor on the substrate, forming a third fin-shaped structure for a first pass gate (PG) transistor on the substrate, and forming a fourth fin-shaped structure for a second PG transistor on the substrate. Preferably, the first fin-shaped structure and the second fin-shaped structure include a first recess therebetween and the third fin-shaped structure and the fourth fin-shaped structure include no recess therebetween.
