Semiconductor device
First Claim
1. A semiconductor device, comprising:
- a substrate; and
a first electrical fuse and a second electrical fuse provided over said substrate, wherein said first electrical fuse comprises;
a first upper layer wire and a first lower layer wire formed in different wire layers; and
a via for connecting said first upper layer wire and said first lower layer wire, wherein said second electrical fuse comprises;
a second upper layer wire and a second lower layer wire formed in different wire layers; and
a via for connecting said second upper layer wire and said second lower layer wire,wherein the semiconductor device comprises a connection portion, formed in an intermediate layer disposed between the first upper layer wire and the second lower layer wire, for connecting said first upper layer wire of said first electrical fuse to said second lower layer wire of said second electrical fuse, andwherein said first electrical fuse and said second electrical fuse are connected in series via said connection portion.

Abstract
A semiconductor device has a semiconductor substrate and a first electrical fuse and a second electrical fuse, which are provided on the semiconductor substrate. The first electrical fuse has a first upper layer wire and a first lower layer wire formed in different wire layers, and a via for connecting the first upper layer wire to the first lower layer wire. The second electrical fuse has a second upper layer wire and a second lower layer wire formed in different wire layers, and a via for connecting the second upper layer wire to the second lower layer wire. The semiconductor device has a connection portion for connecting the above described first upper layer wire of the first electrical fuse to the second lower layer wire of the second electrical fuse. The connection portion connects the first electrical fuse and the second electrical fuse in series.
