Answering Your Questions

Frequently Asked Questions

How do laser marking and wafer sorting contribute to quality assurance in semiconductor manufacturing?

Both laser marking and wafer sorting are integral to maintaining high-quality standards in semiconductor production. Laser marking provides permanent identification of each component, enabling traceability and facilitating the tracking of products throughout their lifecycle. Wafer sorting ensures that only functional dies advance to the packaging stage, effectively filtering out defective units early in the process. Together, these processes help minimise errors, reduce waste, and ensure that only components meeting strict quality criteria reach the market.

What is wafer sorting, and what role does it play in semiconductor manufacturing?

Wafer sorting, also known as wafer testing, is a process performed during semiconductor fabrication where each die (individual chip) on a silicon wafer is electrically tested for functionality. The primary purpose of wafer sorting is to identify non-functional or defective dies before they proceed to packaging, thereby preventing the assembly of faulty components. This step is crucial for enhancing overall yield, reducing manufacturing costs, and ensuring the reliability of semiconductor devices.

What is laser marking, and why is it important in the semiconductor industry?

Laser marking is a process that uses focused laser beams to create precise, permanent marks on materials. In the semiconductor industry, this technique is essential for inscribing critical information onto wafers. The high precision of laser marking ensures that even microscopic marks are clear and readable, facilitating effective traceability and quality control throughout the manufacturing process.
