Increasing demand for LEDs contributes to the growth of the 3D stacking market
The market of LED has increased in recent times because of increasing demand due to its numerous advantages, such as energy efficiency and better performance than traditional lighting systems. LED is being used in various industries like automotive, construction, and lighting. Through 3Dd stacking technology LED size can be reduced and also made more efficient. 3D stacking allows LED manufacturers to maximize the output and reduce the surface area.
According to IEA, in 2022, LED demand increased along with its lighting efficiency. While countries across the globe have started to replace incandescent lamps with LED lighting, it is expected that it will replace them very soon. As per the report, about 50% of the global LED sales are from residential lighting.
According to global residential LED lighting sales by technology in the Net Zero Scenario in 2020 is 43.3% which further increased to 50.5% in 2022.
3D stacking technology used in LED manufacturing allows the manufacturer to make it more efficient and to reduce its size without affecting its output.
Design complexity hampers the growth of the market
3D stacking is used to reduce the size of the product and increase its efficiency, but sometimes it tends to increase the complexity of the design, which in turn requires more expertise to understand. Also, this technology makes the cost of the product much higher than it used to be before the usage of this technology. Thus, apart from having numerous benefits that help in the growth of the market, there are also some factors that hamper the growth of the market.
The 3D stacking market is segmented based on different types
The 3D stacking market is segmented based on different types into logic ICs, imaging & optoelectronics, memory devices, MEMS/Sensors, LEDs, and others. Logic ICs are integrated circuits found in microprocessors and microcontrollers. This allows for denser transistor integration and shorter connection lengths.
3D stacking technology helps in improving optoelectronic systems by combining different sensors into one and reducing their size without affecting their functionality. 3D stacking is also used in the making of memory devices because, due to this technology size of the memory devices can be reduced, and also their capacity can be increased. It also enhances the memory density and reduces the latency.
Microelectromechanical systems (MEMS) and sensors are used in various industries such as automotive, consumer electronics, and healthcare. 3D stacking helps in reducing their size and also helps in integrating them with other semiconductor components.
