Semi Automatic Room Temperature Wafer Bonding Machine for 2 to 12 Inch Wafer Processing

The Semi Automatic Room Temperature Wafer Bonding Machine is a high-precision system for wafer-level and chip-level bonding. By combining mechanical pressure with in situ surface activation technology, it enables permanent bonding at room temperature (20–30°C) without adhesives or high temperature processing. This minimizes thermal stress and material deformation, making it ideal for heat-sensitive and heterogeneous materials. The machine supports wafer sizes from 2 inch to 12 inch and is suitable for research, pilot production, and small to medium scale manufacturing.
