Key Features and Benefits

The powerful features of the DR3000III set it apart in the precision manufacturing field:

Tension-free Application Technology: This is one of its core technological advantages. Minimizing tape tension before lamination effectively controls wafer warpage after back-side grinding, which is crucial for handling large-size, ultra-thin wafers.

Low-stress lamination control: The equipment features low-tension bonding and adhesive stress control, significantly reducing the risk of wafer pattern damage during lamination.

Wafer compatibility: While designed for 300mm wafers, it is backward compatible with 200mm wafers and supports special processes with optional features such as a heated chuck table (Max 100°C) and heated rollers (Max 60°C). Furthermore, it effectively handles bumped wafers and wafers with a certain degree of warpage.

High automation and intelligence: The equipment is equipped with:

Automated material handling: Supports front-opening wafer cassettes (FOUP) / open cassettes, with a built-in robotic arm for fully automated loading and unloading.

Precise alignment: Employs a non-contact CCD alignment system to ensure lamination accuracy.

Intelligent Monitoring: Equipped with a log file function for data traceability; tape sagging detection prevents malfunctions. An optional wafer mapping scanner enables automatic incoming material inspection.

Compliant with High Industry Standards: The equipment complies with SEMI S2/S8 safety and environmental standards and is available with optional SECS/GEM communication protocols for seamless integration into modern semiconductor factory automation systems.

User-Friendly Operation: A large touchscreen combined with a recipe function makes operation simple and intuitive. Users only need to call up the recipe for the corresponding product to automatically complete all parameter settings.

Working Principle: Before the backgrinding process, the DR3000III precisely adheres protective tape to the patterned side of the wafer using a tension-free method to prevent mechanical damage or chemical contamination to the front side of the wafer during subsequent high-speed grinding.

Application Areas: The DR3000III is primarily used in the following key areas:

Semiconductor Manufacturing: Logic chips and memory chips (DRAM, NAND Flash, etc.): Protecting the delicate circuit structure on the front side of the wafer in advanced processes. Advanced Packaging: Provides wafer protection during the increasingly larger 300mm wafer-level packaging processes (Fan-In WLP, Fan-Out WLP, etc.).

MEMS and Sensors: Protects micromechanical structures and sensor areas during back-side thinning processes.

Power Semiconductor Devices: Processes wafers for power devices such as IGBTs and MOSFETs, reducing on-resistance and improving heat dissipation through thinning.

Collaboration with Other Equipment: On semiconductor packaging lines, the DR3000III typically works in conjunction with the following equipment:

Collaboration with Film Application Equipment: Works in conjunction with the Nitto NEL-MA3000-III tape removal equipment before and after the thinning process. The DR3000III first applies protective tape to protect the wafer from damage during thinning; after thinning, the NEL-MA3000-III precisely removes the protective tape, ensuring the integrity and safety of the ultra-thin wafer throughout the process.

Collaboration with Polishing Equipment: Works closely with polishing machines as a protective step. After the wafers are coated with protective films by the DR3000III, they are then fed into a grinding machine for back-side thinning, reliably ensuring the safety and stability of the grinding process.

Overall, the Nitto DR3000III is a highly specialized, automated, and high-performance wafer protection system. Through its tension-free film lamination technology, it effectively resolves the common issues of warping and chipping encountered with large-sized wafers during the back-side thinning process. It plays a pivotal role in the semiconductor industry, serving as a critical piece of equipment for ensuring the yield and reliability of advanced chip manufacturing.
