PDF Solutions

Developer of solutions for accelerating yield ramp in fabs.


PDF Solutions develops yield-improvement technologies and services for the manufacturing process lifecycle.

The company’s focus is accelerating fab yield ramp, electrical characterization for production control, and big data analytics software for fabless, foundry, test and assembly production control and monitoring.

Electrical characterization is becoming increasingly important because traditional optical inspection cannot see defects that are buried in finFETs and other 3D structures. Moreover, at 16/14nm and beyond, overlay alignment accuracy is moving beyond the resolution of optical systems, which makes it difficult to maintain high yield.
