Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A semiconductor device including a static random access memory (SRAM), comprising:
a first SRAM array comprising a first plurality of bit cells arranged in a matrix;
a second SRAM array comprising a second plurality of bit cells arranged in a matrix;
a plurality of abutting dummy cells disposed between the first SRAM array and the second SRAM array,
wherein:
each of the plurality of abutting dummy cells comprises:

a plurality of dummy gate electrode layers having a length extending along a first direction; and
a plurality of dummy contacts having a length extending along the first direction parallel to the dummy gate electrode layers,

wherein at least one of the plurality of dummy contacts extends, in the first direction, continuously across the plurality of abutting dummy cells; and
a first-type well continuously extending from the first SRAM array to the second SRAM array.
