Future of sustainable electronics
WE CONTRIBUTE TO GLOBAL ENVIRONMENTAL SUSTAINABILITY BY IMPROVING THE POWER EFFICIENCY OF KEY SEMICONDUCTOR COMPONENTS AND OPTIMIZING THEIR MANUFACTURING PROCESS
Identified as one of the Key Enabling Technologies by the EU in 2020, compound semiconductors are expected to replace silicon in a variety of devices
Recent developments in compound semiconductors application as high-efficiency power devices, light emitters, and sensing devices demonstrate their undeniable positive impact on energy efficiency and the environment.
Consumer electronics such as TVs, computers, smartphones, wearables, and other consumer devices contribute to almost two-thirds of ICTs total power consumption globally. The number of these devices is rapidly growing and is projected to reach 30.9 billion units worldwide by 2025. All of these contain multiple compound semiconductor components - the main source of power consumption.
Smartphones alone are estimated to consume up to 11000 GWh of energy per year. Lion's share of it is caused by various components based on semiconductors. With Kontrox, power consumption can be drastically reduced by transforming properties of semiconductor materials and enabling mass adoption of greener technologies such as microLED.
Over 50% of global ICT energy consumption is caused by consumer devices; almost all of them contain a display - component with enormous power consumption.
GREENER DISPLAY TECHNOLOGY
Displays are accountable for lion's share of energy consumption in the majority of consumer electronic devices; e.g. in smartphones, display takes up to 50% of device’s total power usage.
Replacing the existing OLED and LCD display would enable enormous energy savings. Advanced miniLED technology could be the key; it demonstrates unprecedentedly low levels of power consumption - 40% less than OLED and up to 90% less than LCD. If all existing OLED and LCD displays are replaced with microLED, energy savings could account for up to 360TWh /year the equivalent to all renewable energy produced in the EU in 2019.
Despite its highly promising energy efficiency properties, microLED technology has been presenting certain preventing it from being adopted on a mass level. These challenges can be overcome with Kontrox, which not only improves energy efficiency but also boosts illumination and performance uniformity of the microLED chips.
Sources of energy consumption within the global Information & Communication industry:
RF power amplifiers 35-40%
Sensing and recognition devices 1-3%
Applied to various semiconductor components used in an average smartphone Kontrox can reduce device's power consumption by up to 35 %
If all existing OLED and LCD displays are replaced with microLED, energy savings could account for up to 360TWh /year - the equivalent to all renewable energy produced in the EU in 2019
WASTE MATERIAL REDUCTION
Semiconductor manufacturing processes involve multiple manufacturing stages and hundreds of generic materials to achieve the final product. Thus, the industry generates significant quantities of spent solvents, liquids containing metals, and other (hazardous) waste.
The amount of waste is directly linked to manufacturing yields that are largely affected by the number of material or dimensional non-uniformities. Simply put – the higher the yield is, the waste is produced.
Kontox has proven to transform material surfaces into almost defect-free crystalline layers, thus improving material homogeneity and significantly improving manufacturing yields. This leads to “cleaner” production process with less waste.
