Laser Marking
Semiconductor Laser Marking is a precise, non-contact method used to engrave or mark identifying information, such as serial numbers, QR codes, logos, or other data, onto semiconductor wafers, components, and packages. This process is crucial for tracking, quality control, and traceability across manufacturing and distribution.
Integra Technologies recently acquired a CSM2000 Wafer Level CSP Marker to expand our WLCSP offering. The CSM2000 is the fully automated wafer-level laser marking system for the backside of a wafer.
Take a look at some of our most frequently asked questions:
Q: Does Integra have an automated systems for wafer-level laser marking?
A: Yes, the CSM2000 which has automation for 150mm and 200mm wafers
Q: Does the CSM2000 have automated wafer alignment?
A: Yes, the system has a high accuracy twin arm robot for increasing the system WPH (wafer per hour). Also, it minimizes the wafer alignment time by optimizing the wafer pre-alignment system.
Q: What are the key features of laser marking?
A: Some of the key features include:
- Precision and Accuracy - Laser marking can create extremely detailed, small markings without damaging the delicate structure of the semiconductor components. This is essential as components become more compact.
- Non-Contact Process - Since lasers do not physically touch the surface, the risk of contamination or mechanical damage is significantly minimized, which is critical in a cleanroom environment.
- Permanence and Durability - The markings are resistant to wear, high temperatures, and other environmental factors, ensuring long-lasting traceability through various stages of the semiconductor lifecycle.
- Adaptability for Various Materials - Laser marking can be used on a range of materials, including silicon, metals, and ceramics, commonly found in semiconductor manufacturing.
Q: How does the CSM2000 maintain position accuracy?
A: CSM2000 has a very high marking position accuracy by using AGC (Automation Grid Calibration) which compensates the marking position distortion. The CSM2000 uses the latest galvanometer and guarantees the marking position repeatability. Built-in galvanometer checking system detects thermal drift of scanner and prevents the many laser problems may cause by it.
Q: Is the CSM2000 system accurate even after long use?
A: Yes, the CSM2000 has the APC (automatic power compensator). Using this function can be maintained until the end of the diode's lifetime.
Q: Can the SST 5100 be used at different temperatures?
A: Yes, the system allows for heating up to 500°C and cooling in an inert gas environment from vacuum levels below 50 millitorrs to pressures up to 40 psig
