Laser wafer trimming and fusing
Our sophisticated solutions are used from sensor production to highly complex mixed-signal circuits, proving their outstanding performance in 24/7 operation every day with our blue-chip customers around the globe.
How does wafer trimming work?
Our systems have been successfully trimming circuits at wafer level for decades, offering maximum flexibility for a wide range of production requirements. They can be equipped with various chuck materials and laser sources to achieve optimal results on the wafer. In addition to being used for offline fusing (also known as memory repair), the systems can be connected to external test systems via the ATI (Advanced Tester Interface). Equipped with an SECS/GEM interface and fully automated, the systems enable seamless integration into any production environment.

What Is wafer trimming/wafer fusing used for?
In the manufacturing of modern mixed-signal devices, the precise use of laser technology enables real-time modification of electrical circuit properties. Test systems are either connected directly to the trim system to measure the circuits in real-time and fine-tune them using lasers (“Wafer Trim”), or pre-created fuse maps from offline testers are used to optimize the circuits based on the test results (“Wafer Fusing”).
These processes not only improve the accuracy of the circuits but also provide a cost-effective alternative to conventional e-fusing by reducing production costs and enhancing the quality of the end products.
