Enhanced safety: Our sensors can monitor hoist movement, vibrations, and payload weight in real-time, preventing collisions, overloads, and equipment damage.They have the ability to alert operators of potential hazards and trigger automated safety measures.
Optimizing efficiency: Data from our sensors can be used to optimize hoist movement paths and speeds, reducing wear and tear on equipment and potentially improving throughput.
Wafer Dicing
Application:
Our sensors can monitor blade sharpness, vibration, and pressure during dicing processes, ensuring consistent wafer quality and reducing chipping or breakage.
Predictive maintenance: Our sensor data can be used to predict blade wear and schedule timely replacements, preventing damage to wafers and costly downtime.
CMP System
Application:
Monitoring the force applied to the polishing plate, head, and wafer carrier is crucial for preventing stress concentration and potential damage to the wafers. By identifying areas of excessive force, your module can help optimize the polishing process and maintain consistent quality.
Continuously monitoring the force also allows for proactive maintenance on the equipment, preventing downtime and ensuring optimal performance.
Accurately gauging the interaction between the polishing pad, slurry, and head is essential for achieving uniform and desired results. Our module’s ability to monitor these parameters can help fine-tune the process for better consistency and yield.
Analyzing the slurry performance through the sensor data can offer insights into its effectiveness and degradation, leading to optimized utilization and reduced waste.
FOUP
Application:
Temperature sensors: These sensors monitor the temperature inside the FOUP to ensure that the wafers are being stored at the correct temperature.
Humidity sensors: These sensors monitor the humidity inside the FOUP to prevent moisture from damaging the wafers.
Vibration sensors: These sensors monitor the vibration of the FOUP to detect any potential damage.
Particle sensors: These sensors monitor the level of particles inside the FOUP to ensure that the wafers are not being contaminated.
Pressure sensors: These sensors monitor the pressure inside the FOUP to ensure that the wafers are not being damaged by changes in pressure.
Light sensors: These sensors can be used to detect if the FOUP has been opened, which could allow contamination to enter.
Minimizing defects: Precise pressure and vibration monitoring can help maintain mask alignment and prevent micro-scratches, ensuring optimal yield and reducing scrap due to imperfections.
Wafer Scrubbing Process
Application:
Pressure Sensors: By monitoring the pressure applied to the wafer during scrubbing, these sensors can help prevent excessive force that could lead to cracks or breakage. Real-time adjustments can be made to maintain optimal pressure based on wafer thickness and other factors.
Benefits of Sensor Monitoring:
Reduced damage: Real-time monitoring allows for proactive adjustments to the scrubbing process, minimizing the risk of scratches, cracks, and other defects.
Improved yield: By preventing damage, sensor monitoring helps ensure higher yields of usable SiC wafers, leading to cost savings and increased efficiency.
Process optimization: Data collected from sensors can be used to optimize the scrubbing process for different types of SiC wafers and cleaning conditions, leading to improved quality and consistency.
Predictive maintenance: Sensor data can be analyzed to predict potential issues with equipment or cleaning solutions before they cause damage, allowing for preventive maintenance and downtime reduction.
