Project to advance VCSEL high volume supply chain


IQE plc, a global supplier of advanced semiconductor wafer products and services, has joined a new consortium to establish a pan-European supply chain capability for the high volume production of vertical cavity surface emitting lasers (VCSELs) for infrared illumination, data communications, gesture recognition and industrial heating applications.


The aim of the programme is to establish a European based production capability to bring VCSEL manufacturing to a level comparable to LED and CMOS manufacturing.


By bringing together existing high volume production facilities at IQE, along with key end users, the consortium will deliver an end-to-end production supply chain offering signifi cant reduction in the cost-per-function for VCSEL devices by reducing GaAs processing costs whilst increasing device performance.


VCSELs are key enabling technologies for a wide range of applications where demand is proliferating rapidly as this advanced laser becomes the device of choice for many high volume applications including:


 Gesture recognition, for gaming and non-contact navigation (e.g. TV, smartphone, tablet)


 Depth imaging for 3D vision, using ‘time of fl ight (ToF)’ technology, driving next wave of handset innovation for must have new phones


 Production line heating automation: signifi cant operating effi ciencies can be achieved using VCSEL technology with applications requiring tens of millions of devices


 Low energy optical storage and fast switching in high capacity data centres, servers and ultra-high speed computing


 High speed datacoms, including Active Optical Cables (AOC)


 Ultra-High Density magnetic Storage using Heat Assisted Magnetic Recording (HAMR)


 Illumination for IR cameras for security, safety, night vision


 Other industrial heating applications including paint curing and commercial print shops


 Cosmetics and healthcare including hair removal, antiwrinkle, blemish reduction


IQE has demonstrated advances in VCSEL technology including an established 100mm VCSEL process which has been enhanced by the recent launch of its new 150mm VCSEL wafer products for high volume applications, announced in March 2014.


The Euro 23million VCSEL Pilot Line for IR Illumination, Datacom and Power Applications (VIDaP) programme, whose partners include IQE, Philips, STMicroelectronics, Sick and Sidel, will receive funding under the European Commission’s ENIAC program with IQE receiving signifi cant support from the Welsh Government.


New 650V normally-off GaN transistor family


GAN SYSTEMS, a developer of gallium nitride power switching semiconductors, has announced fi ve new normally-off 650V GaN transistors optimised for high speed system design.


The new 650V enhancement mode parts feature a reverse current capability, zero reverse recovery charge and source-sense for optimal high speed design. RoHS compliant, the devices are delivered in GaN Systems’ near chipscale, embedded GaNPXpackage which eliminates wire bonds thereby minimising inductance. This package also optimises thermal performance and is extremely compact.


Girvan Patterson, President of GaN Systems comments:”With these new 650V parts as well as our recently- announced 100V family, GaN Systems offers a very wide range of parts which are available for are sampling now. Applications include high speed DC-DC converters, resonant converters, AC motor drives, inverters, battery chargersand switched mode power supplies.”


The GS66502P, GS66504P, GS66506P and GS66508P are respectively 8.5A/165mΩ, 17A/82mΩ, 25A/55mΩ and 34A/41mΩ parts, while the GS43106L is a 30A/60mΩ cascode.
