Patent ID: 8847301

Claim:
A semiconductor device comprising: a substrate; a first word gate formed over the substrate; a second word gate, formed over the substrate, which extends parallel to the first word gate; a first control gate formed at a lateral side facing the second word gate in the first word gate; a second control gate formed at a lateral side facing the first word gate in the second word gate; a first connection portion and a second connection portion, formed over the substrate, which connect the first control gate and the second control gate, and are separated from each other; and at least one diffusion layer, formed in a region located between the first connection portion and the second connection portion in the substrate, which extends from the first control gate to the second control gate, wherein the first control gate includes a first disconnection portion between the first connection portion and the diffusion layer closest to the first connection portion, the second control gate includes a second disconnection portion between the second connection portion and the diffusion layer closest to the second connection portion, the first word gate is not disconnected in a portion overlapping the first disconnection portion, and the second word gate is not disconnected in a portion overlapping the second disconnection portion.
