The TEL CELLESTA™-i MD wafer cleaner is an advanced single wafer cleaning system developed for semiconductor manufacturing processes requiring high cleanliness, excellent process control, and stable wafer yield performance.
Designed for 300mm wafer production, the CELLESTA™-i MD supports advanced semiconductor manufacturing where particle removal, surface contamination control, and pattern protection are critical factors affecting device performance and reliability.
As semiconductor technology continues moving toward smaller process nodes and more complex device structures, wafer cleaning has become one of the most important processes in semiconductor fabrication. Advanced cleaning equipment must remove contamination while protecting delicate wafer patterns.
What is TEL CELLESTA™-i MD Wafer Cleaner?
The TEL CELLESTA™-i MD is a single wafer cleaning system used in front-end semiconductor manufacturing. Unlike batch cleaning equipment that processes multiple wafers simultaneously, single wafer cleaning provides individual wafer process control with improved cleaning uniformity and repeatability.
The system is designed for advanced semiconductor processes where even microscopic particles or surface residues can negatively impact device performance and production yield.
Typical applications include logic semiconductor manufacturing, memory production, and advanced wafer processes requiring precise contamination control.
Why Semiconductor Wafer Cleaning is Critical
During semiconductor fabrication, wafers experience hundreds of process steps including lithography, etching, deposition, and implantation. These processes can introduce different types of contamination.
Particle contamination
Organic residues
Metal contamination
Chemical residues
Etching by-products
Without effective cleaning, contamination may cause electrical defects, reduced yield, device reliability problems, and shortened product lifetime.
TEL CELLESTA™-i MD Key Technologies
300mm Single Wafer Processing
The CELLESTA™-i MD is designed for 300mm wafer manufacturing environments. Single wafer processing allows precise control of chemical exposure, cleaning conditions, and drying performance.
Advanced Particle Removal
The system provides high-performance particle removal while minimizing damage to sensitive semiconductor structures. This capability is important for advanced devices with smaller geometries and complex patterns.
Pattern Collapse Prevention Technology
As semiconductor patterns become smaller, wafer drying becomes increasingly challenging. Excessive surface tension during drying can damage fine structures.
The CELLESTA™-i MD incorporates advanced drying technology to reduce pattern collapse risks and support next-generation semiconductor manufacturing.
