Wafer-level coating is a specialized process designed for automated dispensing of die attach adhesives directly on whole wafers, which are then cured into die attach films in subsequent procedures.

FUNSONIC ultrasonic coating technology for semiconductor wafers is well-matched to wafer coating applications. It delivers outstanding performance in processing throughput, precise film thickness regulation and excellent material layer uniformity. After thermal curing or UV curing followed by wafer dicing, thermocompression bonding is adopted to realize chip interconnection. This process yields uniform adhesive fillets and well-defined tiny fillet radii.

When deploying ultrasonic wafer coating technology, key spray parameters including ultrasonic frequency, traverse speed and target coating thickness must be optimized based on actual adhesive materials and technical specifications. In addition, material characteristics exert notable influence on final spraying results. Critical indices such as adhesive viscosity, surface tension and solvent volatility should be fully evaluated during material selection.

 

1. Photosensitive Layer Coating
For lithography processes, ultrasonic coating technology achieves even deposition of photoresist to guarantee high-precision pattern transfer.
2. Protective Coating
Anti-corrosion and anti-scratch protective films are applied on wafers to improve their mechanical durability.
3. Functional Coating
For customized application scenarios, functional coatings with designated electrical or optical performance can be deposited onto wafer surfaces.
