For wafer bond quality inspection.
For qualification of bond quality after pre-bonding, the IR-inspection
system gives first information on the bond quality via a stored image.
A uniform illumination system and an IR sensitive CCD camera are the main
components of the IR-inspection station. Video frame grabbing technology
displays the camera image on the process monitor. The image of each wafer
can be optionally stored on hard disk drive as graphic file.
Features
- IR inspection station for quality control
- Automatic image acquisition of all bonded wafer pairs
- High sensitivity given by high resolution IR-CCD-camera
