ABSTRACT:
A fuse window structure and method for forming the same for a semiconductor device with a fuse and a cutting site on the fuse, the structure having (1) a first oxide region substantially in register with the cutting site, the first oxide region having a first thickness, (2) a second oxide region substantially in register with a first land generally surrounding the cutting site, the first land generally in register with the fuse, the second region having a second thickness, and (3) a third oxide region substantially in register with a second land generally surrounding the fuse, the third region having a third thickness different than the first thickness. Different fuse window structures are formed by using etch stops with different configurations, each configuration differing with regard to coverage of the three oxide regions.
