The low-k film applied to the insulating film of high-speed logic components has low mechanical strength. If ordinary blades are used for cutting, the risk of low-k film peeling will occur. This process of removing low-k film and corresponding wiring layer by laser is laser slotting process.
Compound semiconductors such as GaAs (gallium arsenide) are used in high frequency devices. When using the existing diamond blade to cut compound semiconductor, the feed speed is slow and it is difficult to obtain high productivity.With the trend of high integration, high-strength thin chip manufacturing technology based on SIP (system in package) and other technologies has become necessary.
