Nova and imec Developed Innovative Scatterometry Approach for Self-Aligned Quadruple Patterning (SAQP) Process Control

SAN JOSE, California, February 22, 2016 /PRNewswire/ --

    Nano-electronics research center imec and Nova Measuring Instruments (Nasdaq: NVMI), a
leading innovator and key provider of metrology solutions for advanced process control
used in semiconductor manufacturing, announced today at the SPIE advanced lithography
conference that they are jointly developing an innovative scatterometry approach to enable
SAQP process control. The initial results will be presented during the conference.  

    As 193nm immersion lithography is reaching its optical resolution limit using single
exposure, advanced multipatterning concepts are studied to reach lower nodes. Targeting
the N7 node, self-aligned quadruple patterning (SAQP) is an advanced patterning approach
that uses pitch splitting to extend the capability of double patterning (SADP) 193nm
immersion lithography. Nova and imec jointly developed an approach based on scatterometry
technology to determine the main contributors to the CD (critical dimension) variation
between different populations of lines and spaces. Using parallel interpretation of
multiple scatterometry targets with slightly variable pitches, the researchers revealed
that scatterometry is capable of measuring different space populations, and the developed
metrology solutions can be utilized to monitor and control each process step of SAQP
patterning.

    "Collaborating with Nova has enabled us to develop a method to improve process control
in SAQP for the most advanced nodes," said An Steegen, senior vice president process
technology at imec. "Such collaboration is helping the entire semiconductor industry to
lower risks and shorten the time to market for the next generation technologies by
delivering innovative metrology solutions for the key process control challenges ahead."

    "We are excited with the opportunity to collaborate with imec, join its Affiliation
Program and demonstrate the value of our optical CD for early R&D stages," said Dr. Shay
Wolfling, Nova's CTO. "We believe that the growing process challenges arising from the
advance technology nodes require close partnership between research centers, customers and
vendors and this is part of Nova's stated long-term strategy. Such collaboration with imec,
early in the development cycle, allows us to align our technology roadmap accordingly and
contribute to our customers' success."
