Abstract:
A semiconductor device includes a semiconductor substrate having a fuse region and an interconnection region, a first insulating layer formed in the fuse region and the interconnection region, a fuse pattern formed on the first insulating layer in the fuse region, the fuse pattern including a first conductive pattern and a first capping pattern, an interconnection pattern formed on the first insulating layer in the interconnection region, including a second conductive pattern and a second capping pattern, and having a thickness greater than the thickness of the fuse pattern, and a second insulating layer formed on the first insulating layer and covering the fuse pattern.
Abstract:
Provided is a fuse structure of a semiconductor device. The fuse structure may include an insulating layer pattern structure, a fuse and a protecting layer pattern. The insulating layer pattern structure may be formed on a substrate. The insulating layer pattern structure may have an opening. The fuse may be formed in the opening. The protecting layer pattern may be formed in the opening of the insulating layer pattern structure to cover the fuse.
Abstract:
A reference wafer for calibrating a laser and a camera and checking laser accuracy and spot size. The reference wafer may include a light absorption layer on a semiconductor substrate and a light reflection layer pattern on the light absorption layer. The light reflection layer pattern may include a first pattern for checking the laser accuracy and spot size and a second pattern for calibrating the laser and camera. A first anti-reflective layer may be introduced between the light absorption layer and the semiconductor substrate, and a second anti-reflective layer may be introduced between the light absorption layer and the light reflection layer pattern.
