FSM launches Ultra Fast 3D Inspection system at Semicon West.

The UltraFast 3D Inspection and Metrology system is a high throughput system that measures the height of all (100%) micro-features on a wafer surface such as micro bumps, Copper nails, Cu pillars, redistribution layer (RDL) bumps, and others.

Instead of time consuming scanning or measuring one micro feature at a time, our technology employs simultaneous area measurement of all features in the footprint of the measurement beam. The beam can be several mm by several mm sized and captures all features regardless of pitch. In case of high density I/O chips this can be hundreds to thousands of features in a single field of view.
Applications are manifold. It enables rapid 100% height measurement of all features on a wafer. Analysis features include height maps across the wafer or dies, as well as co-planarity determination. In parallel to the height information optional defect inspection can be employed. This makes the FSM 3D inspection and metrology system a powerful tool for advanced 2.5D/3D packaging process. It can be used for yield improvement, incoming and outgoing quality control.
