Photonics Systems Group and ESI expand licence agreement towards wafer trimming

The Photonics Systems Group, a market leader in laser systems for micromaterial processing, is expanding its licence agreement with ESI, a manufacturer of laser-based micromanufacturing systems and component test systems. In addition to the exclusive licence rights to the circuit trim product range, the Group also holds the patents for the production, service and support of the wafer trimming systems from November 1st, 2020.

The Photonics Systems Group first acquired the exclusive licence rights for ESI’s circuit trim product portfolio back in February. With the signing of the addendum, the US company is now passing on its many years of experience to the Germany-based subject matter expert and is withdrawing from the market segment of laser trimming completely.

This means that all licences and rights for the production, service and support of the entire trimmer portfolio are exclusively in the hands of the Group. The aim of the expanded agreement is now to ensure worldwide service and support for the M350, LT22XX, LT31XX and LT41XX systems and to further develop the product market for the companies within the Group.

“We were keen to ensure that our existing customers received continuous consultation and support,” says John Williams, VP and General Manager of the Equipment & Systems Division at MKS Instruments. “We are pleased that the licence agreement means we can retain our many years of expertise through the Photonics Systems Group and provide our customers with high-quality support.”

“The acquisition of the already established product lines is an extremely valuable opportunity for the Group to further establish ourselves as a manufacturer of wafer and circuit trimming systems,” explains Markus Nicht, CEO of the Photonics Systems Group. “This allows us to significantly strengthen our position in comparison with the competition as an experienced, international company in the European market, and especially the US market.”
