IQE’s subsidiary NanoGaN purchases quasi photonic crystal patents from Luxtaltek, complementing nano-imprint lithography capability
Epiwafer foundry and substrate maker IQE plc of Cardiff, Wales, UK says that its subsidiary NanoGaN Ltd has (in exchange for a one-off payment of $0.5m) secured the purchase and assignment of a portfolio of 54 patents from LED epiwafer and chip maker Luxtaltek Corp of Miaoli County, Taiwan, spanning a range of novel technologies and applications based mainly on quasi photonic crystals (QPC).
The advanced materials technology complements the IQE’s organic development of nano-imprint lithography (NIL) and broadens the potential application of NIL beyond IQE’s current focus on advanced distributed feedback (DFB) lasers. The patents acquired have applications in optical components including vertical-cavity surface-emitting lasers (VCSELs) and edge-emitting lasers, modulators, silicon photonics, fiber-optic systems, micro-LED displays, image sensors including diffractive optical elements (DOE) and biosensors.
IQE’s board believes that, due to its existing in-house NIL capability, the firm is well positioned to commercialize the new technology.
“Over the last few years, IQE has developed an exciting and strong IP portfolio which, coupled with the expertise and manufacturing capability to commercialize these new materials technologies, has uniquely positioned IQE as the clear global leader in providing advanced compound semiconductor technology solutions,” says IQE’s chief executive Dr Drew Nelson. “This significant addition to our IP portfolio provides the group with additional competitive advantages that will secure our entry and maintain our leadership across a range of new and emerging technology applications, and offer our customers access to a unique portfolio of materials expertise,” he adds.
