New materials and chip options in the 5G era

As 5G technology continues to evolve, smartphones are following suit, with even Apple, which has been the slowest to update its hardware facilities, launching 5G phones this year. According to the latest data from Strategy Analytics, 5G smartphone shipments are forecast to reach 234 million units in 2020, accounting for 20% of the overall number of smartphones sold. Compared to 18.6 million units in 2019, the number of 5G smartphone shipments in 2020 has increased by nearly 12 times as much, and it is believed that 5G phones will become mainstream in the next few years with the full rollout of 5G infrastructure.
In addition to cell phones, 5G also brings profound changes in the Internet of Things, artificial intelligence, and cloud data. The further development of intelligence and automation cannot be achieved without the support of related hardware and materials.
I. New materials in the 5G era
5G has high capacity, ultra-high speed, low latency and other characteristics, so it can be widely used in the Internet of Things, artificial intelligence and cloud data, etc. Some analysis shows that the 5G signal is 11.2 times faster than the 4G signal, reaching 8Gbps, and the download speed can even reach 1.58GB/s, which is as fast as copying materials to the computer with a USB flash drive.
5G network its information dissemination is through microwave millimeter fluctuations, so for the material to put forward higher requirements. Here are some examples.
For power switches, motors, electromagnetic shielding materials, etc. for soft and hard porcelain materials put forward higher requirements; for power switches, motors, electromagnetic shielding materials, etc. for soft and hard porcelain materials put forward higher requirements for signal sources need better semiconductor materials; for microwave devices, isolators, etc. for microwave magnetic materials put forward higher requirements.
For soft magnetic composite materials, in recent years, the country is paying attention to the research and development in this field. Because soft magnetic materials have high frequency permeability, low loss hood characteristics, which is in line with the 5G era of high frequency, high stability, high consumption of material needs, SMC materials are representatives of soft magnetic composites, the future has a good market.
At present, the semiconductor has developed from the traditional silicon material to now use high performance silicon carbide and gallium nitride, bringing the frequency band to 100GHZ and power over kilowatt, which can fully meet the demand for semiconductor materials in 5G era.
5G millimeter level electromagnetic wave penetration is strong and attenuation is poor, so the requirements for electromagnetic shielding materials are very high. The current solution given by the market is to achieve electromagnetic shielding through the application of conductive materials. For example, through the use of conductive cloth, conductive adhesive, conductive foam, conductive coating, conductive shielding tape, wave-absorbing materials, etc., through the conductive materials to achieve shielding signal.
Second, the choice of chips in the 5G era
No matter in any era, the chip is the core component. Once the are using Moore's law 0 and 1 computing storage of semiconductors as materials, future chips may perhaps use open source chips, biochips, spin chips, quantum chips, photonic chips, etc..
Hitachi first made in 1989 in the laboratory Lee FinFET, and chip development to the potential of DRAM technology is about to run out, perhaps in about 2025 will begin to use carbon nanotube materials to get rid of the silicon chip monopoly. In the next decade perhaps the semiconductor will use photons instead of electrons to achieve higher and wider broadband; and then perhaps after the introduction of quantum computing, such as 90% of the photon bits mixed with 10 quantum bits, which may be somewhat pie-in-the-sky, but the technology update in the accelerated, counter-push the researchers to innovate, how the future, worth all expectations.
