Ingots Slicing Machine
The ingot slicing (silicon, sapphire, SiC, GaN) is the first step in chip making. High-speed saws slice the ingot into "wafers", which are then ground to a mirror smooth surface. During the ingot slicing process, it is important to stop the machine immediately, if the diamond wire breaks
The ingots are slowly lowered and cut into wafers for several hours during the sawing process. The trend is to use thinner diamond wires to minimize the cutting width and then get more wafers from a single ingot with significantly faster production speed.
If the diamond wire breaks during the ingot slicing process, it is crucial to stop the machine immediately. A Marposs acoustic sensor can be integrated inside the ingot-slicing machine to immediately stop the machine once it has detected the wire breakage, and then ease the following operation of wire replacement.
- Immediate machine stop to avoid further damages
- Fast wire breakage detection (few ms)
- Automatic sensor setup according to machine’s background noise
- Increased machine safety
