Tudor Brown, one of the founding team at processor IP licensor Arm Ltd. has taken an advisor position at microLED startup Poro Technologies Ltd. (Cambridge, England).

Brown served in many senior roles at Arm including COO, CTO and engineering director before he left in May 2012. Since then he has taken on a number of technology company directorships.  

Porotech was founded in April 2018 by Tongtong Zhu, CEO, and Yingjun Liu, CTO and Professor Rachel Oliver, chief scientific officer, to develop microLEDs based on gallium-nitride.

The company has a wet chemistry method of creating a porous buffer zone benefit the surface of a GaN layer. After the porosity is introduced it is possible to create natively emissive red, yellow, green, and blue diodes. Having all colours available in a single wafer should provide an advantage in creating microLED displays (see CEO interview: Porotech’s Zhu on the porosity advantage).

Asian experience

Brown has a great deal of experience in southeast Asia and Greater China where much of the display industry is now based.

Last month Brown resigned as a director of Chinese foundry chipmaker Semiconductor Manufacturing International Corp. (SMIC) after nine years. He remains on the boards of Lenovo, Garrison Technology Ltd., Marvell Semiconductor and Ceres Power Holding Ltd.
