Future trends in semiconductors
When it comes to the future of semiconductor chip development, China has set its sights on two key research focuses: enhancing integration density and reducing the size of semiconductors to a nano and micron scale. probe test Despite possessing the expertise to create top-of-the-line chips, China's industrial infrastructure for semiconductors remains lacking. As a result, although Chinese experts may have the ability to analyze and design these cutting-edge chips, they still rely on developed nations such as Europe and the United States for fundamental information on manufacturing semiconductor chips. To put it plainly, without adequate resources or materials, advancement is hindered.
In addition, as semiconductor materials continue to shrink in size, there is a growing demand for them to possess high efficiency, heat dissipation capacity, and yield requirements. Therefore, a careful approach to material management is crucial in order to ensure that only top-quality materials are utilized and can withstand the challenges they may face. This is especially evident in the production technology of semiconductor epitaxy, where students are expected to excel in designing advanced optoelectronic chips using superior semiconducting materials. wafer probing For instance, while current density may not be a major concern for semiconductor LED work, it becomes crucial when dealing with higher-power applications such as semiconductor lasers. We can observe this through examples like blue and green lasers, which have been under development for over two decades and are now being successfully commercialized in countries like Japan and the United States. However, China still faces some obstacles in this area. Our blue-green lasers struggle with limited power and resource consumption due to subpar composite product quality that cannot handle high current and voltage demands. Despite having access to valuable information from these lasers, the Japanese government refuses to share their refined epitaxy materials or advanced technology necessary for developing cutting-edge devices like 5G and 66G technologies. These issues are not isolated
A semiconductor epitaxial integration technology can also be used to fabricate semiconductor flexible devices in a simple and effective manner.
From the point of view of photoelectric integration, compound semiconductors have greater advantages than silicon-based materials, as well as better tolerances for material quality. Future semiconductor development may focus on developing compound semiconductors and integrating them with silicon-based materials epitaxially.
Computer chips based on silicon semiconductors have a limit of 2 nanometers, so the costs and volume of such chips are high. Physics hopes to reduce electron transport time by reducing the distance. By increasing electron mobility and speed, we can achieve or surpass silicon-based chip performance without the need for 2nm, resulting in simplified fabrication.
Moreover, there are also plans to investigate the potential of semiconductor materials and devices in developing fields such as quantum technology, photogenetics, and AR/VR. The utilization of semiconductor quantum dots enables advancements in various areas including single photon sources, detectors, and entangled photons. Additionally, the application of semiconductor weakly coherent light sources allows for modern biological theory to be achieved. In photogenetics, visible semiconductor light sources are imperative for regulating light exposure, while in the realm of artificial intelligence, semiconductor micro-area light sources hold significant potential for AR/VR technology.
