Claim Text:
1. A method comprising: forming a dielectric layer over a portion of a Static Random Access Memory (SRAM) cell, wherein the SRAM cell comprises: forming and patterning a first mask layer over the dielectric layer, wherein the forming and the patterning of the first mask layer includes: thereafter, forming a second mask layer over the dielectric layer; etching the dielectric layer using the first mask layer and the second mask layer in combination as an etching mask, wherein a first contact opening and a second contact opening are formed in the dielectric layer from the opening in the etched first mask layer; wherein the first contact opening extends over and exposes both the first source/drain fin and the third source/drain fin; forming a first discrete contact plug in the first contact opening electrically connected to the first source/drain fin and the third source/drain fin; and forming a second discrete contact plug in the second contact opening connected to the second source/drain fin.
