Chinese patent for JPSA

JPSA awarded laser scribing patent in China


J. P. Sercel Associates Inc., (JPSA) have announced that China P.R. has awarded a patent to JPSA covering the unique laser scribing technology used by JPSA Laser.  The same process has been previously patented by JPSA in the USA, Taiwan, Korea, and Japan.


JPSA’s patented scribing technology permits an industry-leading 2.5um kerf, which provides more die per wafer, higher throughput, less debris, minimized heat affected zone (HAZ), and faster return on investment (ROI). The ChromaDice system significantly increases throughput and yield.



In announcing the new China P.R. patent, Jeffrey Sercel, JPSA’s Chief Technology Officer, said, “This patent protects our growing presence in China’s laser scribing market.  JPSA has long been in the forefront of advancing new laser techniques for LED and semiconductor manufacturing, and we look forward to providing more of our high precision laser systems to manufacturers in China and throughout the world.”

Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
