FormFactor Introduces High Throughput Panel Metrology and


FRT MicroProf® PT Automates Measurement to Reduce Processing Costs on Panels up to 600mm x 600mm

LIVERMORE, Calif., May 31, 2023 (GLOBE NEWSWIRE) — FormFactor, Inc. (NASDAQ:FORM), a leading semiconductor test and measurement supplier, today introduced the FRT MicroProf® PT, a new semiconductor metrology and inspection tool for rectangular panels up to 600mm containing 4-5X more dies compared to a 300mm wafer. With full automation and hybrid metrology capabilities, a single system can perform multiple types of 3D measurements and defect detection on the large format panels, supporting heterogenous integration of chiplets used in advanced package technologies such as fan-out panel-level packaging (FoPLP).

FoPLP and other advanced package techniques stack several semiconductor dies into a single heterogeneous package using connection elements such as microbumps, TSVs (through-silicon vias), and interposers. In device development, the new MicroProf PT with SurfaceSens™ technology incorporates a variety of high-precision sensor options to measure the shape of these inter-die connections, as well as thickness, roughness and other characteristics of the film and metal layers that make up each device. Fully integrating into factory floor automation with SECS/GEM protocols, the tool can also deliver essential defect inspection data for process control and yield improvement.

The MicroProf PT is the latest addition to FormFactor’s Advanced Packaging metrology product family, complementing its established wafer-level packaging product, the MicroProf AP. Its key features include:
