Integrated Yield Ramp

Increase Learning Rates by 2x, Reduce Ramp Time by 50%

Time-to-yield and time-to-volume are vital metrics for success when developing a new process. To achieve these goals, fast and accurate characterization of process-design integration choices is critical for determining the best options for manufacturability. Successful characterization enables much faster time-to-qualification and ramp to full-volume production.

Experience Matters

PDF Solutions has more experience solving yield and production problems than any other organization worldwide. The company has worked on more than 100 yield ramps since 1999 and has improved manufacturing yields over numerous technology nodes, including projects at 7 and 5nm nodes. With its proprietary characterization tools, expertise and unique approach, PDF Solutions helps its clients improve their process ramps and shorten their time to profitability.

Proven Tools and Methodology

PDF Solutions has developed and patented tools and methodologies over the past two decades that provide accurate process characterization, yield models, and variability reduction. For example, our Characterization Vehicle® Infrastructure identifies sources of systematic and random yield loss mechanisms much more efficiently than conventional approaches, accelerating learning rates by 200% or more.

The company has also built unique IP and gained extensive experience in the Logic/SoC, DRAM, and Flash nodes. We have a strong and proven track record of working with clients to reach target manufacturing yields faster than could be achieved by a fully in-house production ramp.

Support for Advanced Nodes and Mature Nodes

Our Integrated Yield Ramp Solution is not just for bleeding edge process nodes. Our IYR team has also helped numerous customers achieve improved learning and stability at mature process nodes. Preventing excursions and reducing manufacturing variability is a concern at every process node, not just the most advanced ones. Our team will be happy to discuss the many ways we can assist your engineering organization on your next product.
