Boston University At War With Apple For GaN Patent Infringement

The university has filed a patent against the consumer electronics giant. The patent relates to a method of growing insulating monocrystalline gallium nitride thin films using MBE
On July 2nd 2013, the trustees of Boston University filed a patent infringement lawsuit against Apple, Inc. in Massachusetts District Court.



The lawsuit refers to infringement of the United States Patent 5,686,738, "Highly insulating monocrystalline gallium nitride thin films". The patent relates to a method of preparing highly insulating GaN single crystal films in a MBE growth chamber. The patent was filed by Theodore D. Moustakas, a professor at the University of Boston (BU) and was granted in November 1997.

Several sources say that Apple has used the technology in its iPhone, iPad and MacBook Air and that Boston University wants compensation and may even request halting future shipments of these devices.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
