Freshfields advises FormFactor on expansion in silicon photonics testing
Dec 23 2025

Global law firm Freshfields has advised FormFactor, Inc. (NASDAQ: FORM), a leading semiconductor test and measurement supplier, on its acquisition of Keystone Photonics.

Keystone Photonics is a Germany-based technology company and a pioneer in optical probing technology for silicon photonics (SiPh) and co-packaged optics (CPO) wafer testing. These technologies are key for next-generation data centers powering AI and high-performance computing – accelerating data communications to handle massive information loads with dramatically lower power consumption.

According to the press release issued by FormFactor, the acquisition strengthens its position at the forefront of this explosive growth, extending its integrated test system leadership for advanced semiconductor packaging and leveraging its unique lab-to-fab position as SiPh and CPO manufacturers leap from concept to high-volume production.

The Freshfields team worked closely with the inhouse team at FormFactor led by Alan Chan (Chief Legal Officer) and Judy Lai (Deputy General Counsel), and consisted of:

Lead: Partner Lars Meyer (Berlin/Frankfurt), Principal Associates Daniel Roggenkemper (Frankfurt) and Alexander Schramm (Berlin, all Corporate/M&A)

Partners: Alexander Schwahn (Tax), Judith Römer (Employment Law, both Hamburg), Merit Olthoff (Antitrust, Brussels), Calise Cheng (Corporate/M&A, Silicon Valley)

Counsel: Philipp Lehmann (Commercial/IP, Hamburg), Uwe Salaschek (Antitrust/ Foreign Direct Investment), Laura Frühauf (Corporate/M&A, both Berlin), Björn Junior (Tax, Hamburg)

Principal Associate: Severin Pretzel (Employment, Hamburg)

Associates: Fabienne Gieshoidt (Tax, Hamburg), Johann von Pestalozza (Berlin), Lukas Goetz (Brussels, both Antitrust/ Foreign Direct Investment), Elvan Böninger (Corporate/M&A, Berlin), Philipp Valanto (Commercial/IP, Hamburg), Kevin Meehan (Corporate/M&A, New York)
