Position Title: CV Design EngineerPosition Location: Taipei, TaiwanRelocation: Not AvailableTravel Req: up to 50% to Customer SitesPDF Solutions, Inc. (NASDAQ: PDFS) is a leading provider of yield improvement technologies, services, systems and analytics for the IC manufacturing process life cycle. Headquartered in San Jose, Calif., PDF Solutions operates worldwide with additional offices in China, Europe, Japan, Korea and Taiwan. Position Summary: PDF is seeking an experienced Design Engineer to join the DFI team, to help define the Design For Inspection®IP. The Design Engineer will need extensive hands on experience in understanding and recreating fail modes and Root Cause Issues along with building VCI layouts.Responsibilities:

• Understand target process fail modes and root causes and be able to probe client/team for information required to simulate the fail mode.
• Understand and comprehend design rules. Using design rules to make test structures robust vs. unwanted fail modes and be able to make educated decisions on which rules can be violated and which cannot
• Build Design-of-Experiments (DOE) for VCi cell designs.
• Plan out DOE from design perspective (what is possible in design space) o maximize sensitivity o isolate fail mode by planning out DOE from process perspective (what are the limits of the process before defects are generated) o Determine key design attributes to vary by planning out DOE for analyst (know the expected signals) ▪ Add factors to make DOE easy to understand ▪ Add factors to make DOE easy to analyze and enter experiment into REC
• Build VCi cell layouts, while making cell designs which isolate the target fail mode and are as robust as possible
• Invent creative solutions to work around design rule limitations and able to modify bitcells to make a test structures relevant to detecting the target failmode and verify cells and fix DRC, LVS and ERC issues. CV Design Engineer
• Provide feedback on tool performance and help to specify new tools by creating specs to help make VCi design work more efficient and higher quality.

Qualifications and Skills

• Master’s degree or higher in Engineering or related field
• Familiarity with semiconductor processing and key fail modes for 28nm, 20nm, 14nm, and/or 10nm technologies
• Familiarity with design rules and understanding the link between design rules and process issues
• Familiarity with yield-related test structures like via chains, snakes, combs and testing techniques for these test structures
• Experience navigating semiconductor designs using basic CAD tools (Calibre, Cadence etc.)
• Experience using the UNIX operating system
• Excellent written and oral communication skills
• Excellent time and project management skills
• Highly professional, self-motivated and self-managed

Preferred Skills/Experience

• (Strongly desirable) Experience using PDF’s CV design environment (REC, blender, runbatch, etc.)
• (Strongly desirable) Experience using DRC and LVS verification tools
• Familiarity with standard cell designs to help create product-like test structures
• Experience with SRAM bit cells, esp. how to modify bitcell to make a test structure which is still relevant to detecting the target failmode
• Experience with voltage contrast measurement tools
