Why Semiconductor Manufacturers Use Laser Dicing Technology
Traditional semiconductor wafer dicing mainly relies on diamond blade cutting. While blade dicing remains widely used, advanced semiconductor materials create new challenges because of their hardness, brittleness, and sensitivity to mechanical stress.
Laser dicing provides several advantages:
Lower mechanical stress
Reduced chipping and cracking
Narrower cutting width
Better die strength
Suitable for fragile semiconductor materials
This makes laser processing increasingly important for next-generation semiconductor applications including electric vehicle power devices, RF components, MEMS, and advanced packaging.
ASMPT ALSI LASER1205 Multi-Beam Laser Technology
Multi-Beam Laser Processing
The key technology of LASER1205 is ASMPT ALSI's multi-beam laser processing technology.
The system uses a Diffractive Optical Element (DOE) to divide the laser beam into multiple smaller beams. This allows multiple areas of the wafer to be processed simultaneously.
The multi-beam structure improves productivity while maintaining excellent cutting quality.
Low Heat Affected Zone (HAZ)
Heat generation is a critical issue during laser semiconductor processing.
Excessive thermal impact can affect semiconductor performance and reduce die reliability.
LASER1205 is designed to minimize the Heat Affected Zone (HAZ), supporting high-quality wafer separation for sensitive semiconductor devices.
ASMPT specifies typical LASER1205 performance values including positioning accuracy below 1.5 μm, cutting width below 12 μm, and low HAZ performance depending on process configuration. :contentReference[oaicite:1]{index=1}
