PDF Solutions® Launches New Design-for-Inspection™ Solution

SAN JOSE, Calif., May 24, 2016 (GLOBE NEWSWIRE) -- PDF Solutions, Inc. (Nasdaq:PDFS), the leading provider of semiconductor electrical characterization technologies, announces today the commercial availability of its Design-for–Inspection™ solution (“DFI”). DFI™ is a next-generation solution for inspection that enables non-destructive inline electrical characterization and process control. With this launch, PDF Solutions also announces that it has received orders for its DFI systems, as described below, from two foundry customers.

Industry Problem

As Moore’s Law advances and chip dimensions continue to shrink, the IC industry has introduced a variety of new, 3-D architectures, such as FinFETs, 3-D NAND, and other advanced 3-D structures, aimed at advancing chip performance. With the introduction of 3-D structures, inline electrical characterization is required for process control. Existing e-beam scanning solutions are not optimized to measure the electrical response of the wafer with the required fidelity and throughput.

Next Generation Inspection and Process Control

DFI™ solves this challenge by placing on-chip instruments with calibrated electrical responses directly in the product wafer without any die area penalty. In addition, DFI is designed to be high-throughput, enabling in-line use. The electrical measurements augment and enhance existing optical defect inspection and metrology. DFI is based on PDF Solutions’ 20 years of yield simulation software and Characterization Vehicle® test chip development. The Company’s co-design of its proprietary on-chip instruments and specialized e-beam tool enables a unique fast scanning approach that is necessary for inline measurement of product wafers.

The Design-for-Inspection™ System

PDF Solutions’ comprehensive DFI™ systems can be deployed across a variety of process nodes. To date, on-chip DFI instruments have been placed in customers’ designs at the 28 nanometer (nm) through 7 nm foundry logic process nodes. The proprietary solution includes software for the design of on-chip instruments, custom e-beam measurement hardware, and additional software to measure and analyze the electrical output.

  • The Company’s on-chip characterization instruments are developed using PDF’s FIRE™ software to analyze customers’ product layouts along with additional proprietary design software. These DFI instruments are based on PDF’s Characterization Vehicle (CV) technology and are designed to be placed in test chips, scribe lines, or in product die, without any area penalty, and to exhibit specific electrical responses.
  • The Company’s eProbe™ 150 series e-beam tools are designed to measure the electrical response of the DFI instruments. This new measure, which PDF Solutions calls an Electrical Response Index, allows for more precise inline characterization of design-process interactions.
  • Exensio-DFI software, a part of PDF Solutions’ Exensio™ Big Data analytics platform, is designed to enable the analysis of the billions of measurements collected from the DFI instruments using the eProbe™.

Multiple Customer Orders and First System Deployed at a Major Foundry

The Company also announces today that it has received orders for DFI systems from two logic foundry customers, the first of which, including the first generation eProbe 150 tool, has already been deployed at one of these customers. The second DFI system is scheduled to be deployed at the second customer later this year. These systems will be used for technology development, volume ramp, and new product introductions at the 10nm process node and below.

“Advances in Moore’s Law require many new technological innovations and a new process control paradigm is one of the key requirements,” said John Kibarian, Chief Executive Officer of PDF Solutions. “Design-for-Inspection is a significant first step on this journey, providing the next generation of characterization, inspection, and process control.”

About PDF Solutions

PDF Solutions enables customers to reduce the time to market of integrated circuits (“ICs”), lower the cost of IC design and manufacturing and improve profitability. The Company has developed proprietary products and provides services that target the entire Process Life Cycle, which is a term used to mean the time from technology development and the design of an IC to volume manufacturing of that IC to product assembly and test.

PDF Solutions’ products and services consist of proprietary test structures and electrical test systems, physical intellectual property, enterprise platform software and professional services. The Company’s Characterization Vehicle® (CV®) electrical test chip infrastructure provides core modeling capabilities, and is used by more leading manufacturers than any other test chips in the industry. The Design-for-Inspection™ (DFI™) solution extends the Company’s electrical characterization technologies into the e-beam measurement of extremely dense test structures, or DFI cells, across an entire fabrication process. Proprietary Template™ layout patterns for standard cell libraries optimize area, performance, and manufacturability for designing IC products. The Exensio™ platform for big data unlocks relevant, actionable information buried in wafer fabrication, process control and test data. The Exensio platform is available either on-premise or via software as a service (SaaS).

Headquartered in San Jose, Calif., PDF Solutions operates worldwide with additional offices in Canada, China, France, Germany, Italy, Japan, Korea, and Taiwan.
