Semiconductor Cleaning Process

Don't miss the "end point" of chamber cleaning and don't overdo it.

A consistently clean chamber environment is essential to maximize throughput and yield. Cleaning based on uncertain time controls leads to the generation of residues and a waste of gas and time. ASTON accurately captures the exact moment of cleaning completion at the molecular level, dramatically improving process productivity.

Never miss the "endpoint" of chamber cleaning, without overdoing it.

  1. 1. Thoroughly Reduce Costs and Time with Optimal Endpoint Detection 

    It monitors reaction byproducts generated during cleaning in real-time. It precisely detects the moment residues are removed and immediately stops the process. This eliminates excessive cleaning and eradicates the waste of expensive gases and time.

  2. 2. Prevent Yield Loss Caused by Insufficient Cleaning 

    It reliably detects any insufficient cleaning, preventing contamination carry-over to the next process. By eliminating the source of particles, it contributes to maintaining high yields across the entire wafer.

  3. 3. Monitor Chamber Conditions and Apply to Predictive Maintenance

    It accumulates and analyzes data on cleaning time trends. This enables early detection of signs of chamber component degradation or anomalies, facilitating "predictive maintenance" that prevents sudden equipment downtime.

Data-driven chamber management achieves both manufacturing cost reduction and throughput maximization, elevating your factory's profitability to a new level.
