KONTROX™ ENABLES UNPRECEDENTED PERFORMANCE OF III-V BASED DEVICES IN MULTIPLE FIELDS OF APPLICATIONS
COMPOUND SEMICONDUCTORS HAVE BEEN IDENTIFIED AS ONE OF THE SIX KEY ENABLING TECHNOLOGIES CRUCIAL FOR FUTURE INDUSTRIAL DEVELOPMENT.
AS A RESULT, THEY WILL PLAY A CRUCIAL ROLE IN ENABLING FURTHER INDUSTRIAL AND TECHNOLOGICAL DEVELOPMENT:
Optoelectronic devices are used to source, detect, and control light; they play a major role in a vast number of applications such as telecommunications, monitoring, and sensing, LIDAR, or industrial manufacturing equipment. Examples of these devices are LEDs, image sensors, IR detectors, communication lasers, to name a few. All these devices are made of compound semiconductor materials...
Technical specifications for optoelectronic devices are becoming more challenging, dictated by the demanding use cases from technology trends. For example, thanks to the expansion of IoT and the deployment of 5G networks the amounts of data exchange are growing exponentially increasing the requirements for communication devices, lasers, and receivers. In autonomous vehicles, manufacturers strive to minimize any risk of failure in LIDAR systems which are commonly using optoelectronic devices like detectors or lasers. The highest reliability of these devices must be ensured, leaving no room for defective components.
Optoelectronics applications problems and performance limitations arise from high concentrations of defects in the interfaces between the materials used to create the chips. Technologies to solve these issues are essential for the industry to follow and meet market demands.
Digital developments and environmental issues have driven the technical specifications for these devices when for instance, country governments are pushing for energy efficiency improvements, reduction of CO2 emissions and increasing sales of new power electronic systems”. As an example, the EV/HEV segment is driven technologically by CO2 emission reduction targets, higher efficiency requirements, or less dependency on the oil industry. The EV/HEV sector is revolutionizing the power electronics industry from market and business perspectives, as well as from technology innovations where GaN is gaining importance thanks to its properties such as higher band gaps, lower conduction losses, and higher electron mobility. These properties enable to reduce the size, and thus the weight of the components and their passives since the switching frequency can be increased while having overall fewer losses, thus making the system more efficient.
Power electronics developments, unlike other ‘More than Moore’ areas, are application-driven rather than technology-driven...
The number of wireless devices expands from mobile phones to the rapidly emerging Internet of Things (IoT). 5G as a standard continues to advance data speeds for mobile video and fixed wireless devices, while also providing connectivity for the massive number of IoT devices and the soon coming vast fleet of interconnected vehicles....
5G devices will exist in an environment that includes more complexity, more components (particularly filters), more performance demands, smaller size, and lower cost components, as well as dual connectivity between cellular and WiFi networks. RF front-end designs for all wireless products are driven by cost, power efficiency, and available space within the unit. They must be small, highly efficient, and able to be manufactured in large quantities to meet fast-growing global demand.
This will only be achieved by implementing novel production technologies capable of improving the quality of the interfaces in the transistor-based devices based on III/V materials such as GaAs or GaN.
Concentrated Photovoltaics is another application where performance is the key, aiming at efficiency levels >40% compared to ~20% of traditional solar cells. These levels can only be reached using multijunction cells of III-V compound semiconductor materials...
These multijunction cells absorb different wavelengths of sunlight in different layers, allowing them to capture more energy from the sun. However, their manufacturing is very expensive, due to which the use of these devices is limited to military or space applications.
Cost reduction will widen the scope of application
Minimizing the defects and increasing the quality of the interfaces not only will increase the efficiency, but help reduce the costs as the yield will be increased resulting in wider usage in a variety of applications.
